Update: MMjoy2 USB 2.0

What is MMjoy2?

A free firmware developed by Mega_Mozg13 for make USB joystick controller using specific versions of Arduino/Teensy prototype boards, without need to assembly circuit boards or write computer code or deal with Arduino "sketches".

Solder tools and skill is need to assembly pins in some Arduino boards, as well to attach potentiometer, sensor, buttons as in any joystick.

Hardware needed: ~5$ Arduino PRO Micro (ATMEGA32U4) clone (or ~20$ Sparkfun/Teensy versions). Other supported boards linked bellow. Sample:



IMPORTANT - Arduino PRO MICRO with ATMEGA43u4, 16 MHZ, 5V.

Firmware : MMjoy2 - is loaded in Arduino board through a USB cable with MMJoy2 JoySetup software:

Tutorial for firmware upload - by Geneb(F15SIM): http://www.geneb.org/mmjoy2/pro-micro-instructions.pdf

Sample of firmware upload, using Teensy 2.0+: http://forum.il2sturmovik.com/topic/18379-teensy-20-mmjoy2-firmware-joystick-controller

Features (latest firmware):

Buttons: Up to 128 - Notice that 128 buttons was possible in some boards only due pinout limitations, see in links bellow.
Buttons connection require use of Diode Matrix or Shift Register circuits. Sample o DIY Shift Register board, by Debolesis (ED forum).

Encoder - up to 6, adjustable "click" times

Axis: Up to 8 axis using the internal 10 bits (1024 points) ADC or up to 8 axis using 12 bits (4096 position) using external ADC MCP3201, 3202, 3204, 3208 (the last digit indicates supported axis number)

Inputs (axis) in analog mode:

Conventional potentiometer, Linear type (B code), 1k to 100k, ideally use 10k.

HALL sensor: Radiometric linear, example Honeywell SS495A1, Allegro A1324

Inputs in digital mode:

TLE5010/5011, KMA200, KMZ60 + MCP3202 magnetic resistence sensors.

* TLE5010/11 has internal ADC 14 bits.

8 way PoV HAT.

Special functions:

- "Shift" (mode) function, allow a physical button press a virtual button if "shift" are ON.
- Compatibility with shift registers used in F-22 PRO, Cougar, Warthog and Cobra M-5 grips, making use this grips "plug-and-play".
- "Joystick" name, VID, PID defined be user as desired, allowing use several MMjoy2 in the same computer.

If you want configure MMJoy as "2 axis and 1(or 0) button joystick" you can.

Update December 2015:



Compatible Arduino boards - should use ATMEGA32u4, ST90USB646, ST90USB1286 m/c (16 MHZ, 5V):

Original topic about MMjoy -now obsolete:



Sokol1

If you want to use the Teensy++ 2.0 board, you can use GenericHID: http://generichid.sourceforge.net/

g.

Gene,

I know some other firmware for use Arduino (like Teensy) boards as joystick controller.
But since MMjoy do the same and more, is configurable, and develop by simmers is (my)
natural choince..

Sokol1

Sokol, what do you do to keep the noise down? I had my Teensy3/Arudino Uno hooked up my supposedly high quality pots, but the outputs jitter... They don't show any jitters with BU0836x or UHID.

Does MMJoy use some special filters? Better, if there is a way to port it over to Teensy/Arduino...

I dont have experience with Teensy, only with Mjoy DIY boards (~8), with pots have no jitter, and some with HALL sensor, is need use shielded cables.

AFAIK - MMjoy firmware are ported for Teensy 2.0 - is just matter or write via USB ISP cable - but not for 3.0

Sokol1

Hi to all. I'm author of software/firmware MMJOY.


Firmware have software filtration algorithms. Have 15 steps of filtration settings.
"Filter #1" - no filtration, clear signal from sensor;
"Filter #15" - maximum filtration;


Any questions and(or) ideas are welcome!

Hi Mega, thanks for the reply! Is the filter function an average of multiple analog reads? Can the algorithm looked up somewhere? I'd like to implement my filter code for my Teensy3...

Look here: https://code.google.com/p/mmjoy/source/browse/
Folder: common_libs
File: MMJoy.c
Function: Axis_Filter()

PS: All project materials are open source.

Yep got it! Thanks! Will look through it tonight!

Does the firmware work with the Teensy++ 2.0?

g.

Not now.
But possible in future, need only a sample "Teensy++ 2.0".

I asked about the Teensy++2.0 because of the work this guy has done:
http://generichid.sourceforge.net/

The extra pins on the ++ would benefit MMJoy I think.

g.

MMJoy main idea is a simple controller for a simple joystick.
I don't want make 'fat cockpit controller' with hundreds buttons/axis/indicators.

About 'Teensy++ 2.0' I asked developers for sample/discount items, and was refused.

Hi, I have bought a Leonardo Pro Micro clone because I want to build a collective for DCS-UH1. It is detected in Windows as Arduino Leonardo and HID device, however in MMJoy-Loader it doesn´t show in the device list. I installed the driver from the JoyLoader_arduino folder, do I have to do something else before using the loader?

1) for first time - manual select from the list 'Scheme'
2) select firmware(hex) file
3) manual input COM port of Arduino.
4) click 'upload...'

Ok, thanks for your help. Now I receive a message about missing libusb0.dll. Where can I download it?

It is a part of Atmel FLIP:
FLIP 3.4.7 for Windows (Java Runtime Environement included)
After install look in Flip\usb\...

Well, still having no luck with my board. I get this message:

Connecting to programmer: .
Found programmer: Id = "¤ ""; type = &#9786;
Software Version = . ; Hardware Version = .
avrdude.exe: error: buffered memory access not supported. Maybe it isn't

Presione una tecla para continuar . . .

Any idea?

let me know one thing.
When device start bootloader on console "device management" you see "COMx port" (where 'x' maybe variable) or "ATMEGA32U4" device?(make screenshots please)

Ok, I see my mistake, I did not tried to launch Joyloader while in bootloader mode (a little difficult, you only have a few seconds after manually restarting the device). Working OK now.
I have one more question: How does the buttons matrix work ? Is it similar to Leo Bodnar's BU0836?
Thanks for your help.

8 seconds bootloader mode.


Yes.
Leo Bodnar's BU0836:

Mjoy original:

PRO Micro (clone) pinnout:


EDIT- For serial connections check Arduino PRO Micro pinout in MMjoy2 Wiki.

6 rows (BR pins) x 6 columns (BC pins) = 36 buttons and 6 analog axis input - number of axis could be increased for 8 using pins from matrix at cost of buttons number. Teensy, Arduino Micro boards has more pints for inputs.

ADC pins is axis input.

Sokol1

Wow, thank you Sokol, that's exactly what I was looking for. I am a nerd in electronics, what kind of diodes are you using in the matrix?

1N4148 or 1N4004 is fine.

Sokol1

A 1N4001 diode should work just fine.

g.

Will this work on my Arduino Micro? It runs on the ATMega32u4, but look different from the Leonardo pro micro. Also, could I use my Uno R3 to program it?

Arduino Micro
Microcontroller ATmega32u4
Operating Voltage 5V
Clock Speed 16 MHz
it is same as 'promicro', you can try.


Only if "Uno R3" support upload 'hex' files.
My "JoyLoader" software to load firmware via bootloader(Atmel FLIP/Arduino and Teensy2).

Downloads/Updates here: https://drive.google.com/folderview?id=0B2zIeYwbAIHOMFlzSkNPZ1NXV1k&usp=sharing

Mega_mozg do you mean that it would be possible to use the Uno R3 with your work....

So let me guess you upload part to the atmega 328p and then the usb comunication to the atmega16u2???? If that's true would you mean to explain for dumbs as i'm a complete begginer and also english it isn't my mother language.

If it's true I'm gonna love you!!!!!

JA, the precondition to test is:



And the answer is yes:

http://rlangoy.github.io/Arduino-Uno-Uploader-Tool/

Entonces lo prueba, hombre.

Use Mega_Mozg "JoyLoader".

Sokol1

...... then i begging to test it tomorrow... Because right now i have to much Guinness

sorry, guys.
No support to "UNO_R3" here crazy hardware "atmega16u2" + "atmega328p".
Only possible with single chip "ATmega32u4" = "Arduino Leonardo" / "Arduino Micro" and clone "Sparkfun ProMicro" .

Small test with DIY board, 1 encoder (incremental/quadrature) from mouse scroll , 1 pot 50k (CH) 1 pot 100k - no brand.



Set as trim in CloD - Fiat Br.20 - Encoder on Elevator (Profunditá)



Buttons:

On "normal" mode = act like keyboard (ON until pressed)

On "S" mode = turn ON in first press and turn OFF on second press (similar to OF-OFF toggle switch).

On "P" and R" mode = Dont get a conclusive result, some random blinks only...

Thanks for that reply mega_mozg... i was thinking about that "two chip" setup from arduino UNO

Also, which one u recommend for MMjoy 2???

E69_Jack_Aubrey,
if you want "ready for use":
"Sparkfun Arduino ProMicro" - 36 buttons + 6 axis, or "Teensy 2.0" - 64 buttons + 8 axis.

PS: now testing "Arduino Leonardo(ATmega32u4)" and results later.

There's any diference between Arduino Micro and the one you said the Sparkfun Arduino ProMicro ... the thing is that for me the less expensive one is the Arduino's one and the Sparkfun it's quite expensive (shipment mainly).

I have seen your post telling Arduino micro or sparkfun clone ....

Also i understand that it's posible to build a shield to increment the inputs????

Hi, I'm having bad response when connecting 10k and 100k pots directly to the axis pins of the Promicro. Buttons work OK. Will I have better results using the MCP3208 chip instead?

Eogund,

You did Windows > C.Panel > Game Controllers calibration process?
With ATMEGA axis stabilize only after do this 1st time.
Or use DXTweake2.

Use only pots 10 ~50k, 100k pick much noise.

Sokol1

only axis possible to increase (with MCP3202/MCP3204/MCP3208), but total no more 8.

if you want more 36 buttons, at plans make a firmware for promicro(train sim) "8*8 = 64 buttons + 2 axis (and possible add axis with MCP320x)"

make fotos, it help to find problem. picture of "JoySetup".

and today updated information of connecting axis to promicro:

Hi
any news regarding the Teensy2++ compatibility?

Hi.

I do not have "Teensy2++".
If community helps with donate (to buy it) or somebody send "Teensy2++" to me I will start work.

sorry for this position, but project non commercial and I waste a lot of money (and time too)...

Hi thx for the answer.
Where in Europe do you live? I could send you a board. Otherwise, I would also be willing to donate money.

Red_Yeti check PM.

Hi community.
What about this solution (as start) for Teensy ++ 2.0
64 buttons (8*8 matrix), and 8 Axis:


PS: my respect to Red_Yeti

That would be cool. It would work nicely with the 8 row, 4 column diode-isolated input boards I had made recently. You could daisy-chain two of them to get the 64 switch inputs.

g.

release [v20140528] support "MMJoy2.f (AT90USB1286-Teensy++2.0, USB2.0)"
not yet tested on hardware, you can try to be first tester!!!

Hi, made a short test with a 5x5 keymatrix. Works for me so far.
I'll do some other tests with encoders and axes this weekend.

Hi, could you replicate the issue with the 7 row?

Hello all

First post ever after lurking for long. I have wanted to make a cockpit/panels using Mjoy/Mjoy16 for years, just now I have both time and money.

Thank you, mega_mozg_13, for making this project and saving me from having to make a PCB.

I'm having some issues, though.

I'm using a Pro Micro clone off Ebay, Windows 7 x64, mmjoy_software[20140528_update2] and mmjoy_firmware_lufa[v20140528_update1]. In JoySetup, I'm using the values loaded after clicking on the "mjoy8" button (6 axis, 28 buttons)

First: at random intervals, anywhere from 1 to 120 minutes, the board restarts itself. Also, JoySetup doesn't update the uptime value in real time, rather it's slower.

Second: I can't make the first 4 axis change value. Axis 5 and 6 work well. I see values for all 6 axis in Sensors(Source/MCU Port/Channel) with a lot of jitter when they're not connected. But only axis 5 and 6 seem to work. In the board itself, pins A3 and A2 work well, pins A1, A0, 10 and 9 don't seem to work. Nothing happens when connected to a pot (100K) or ground.

This happens with 2 different Pro Micro boards in both my desktop and laptop PCs.

Thank you to whoever can help.

Regards

Al

arnsk98

about axis - check this picture, for "promicro" source "IntSensor" can be only 5/6/7/8/13/14:


about random restarts - try to check USB connection (maybe connect active USB HUB with self power source).

great works! make things a lot of easy for somebody not knowing electronics

Thank you, mega_mozg_13

How about this testing "Arduino Leonardo(ATmega32u4)"? working as well?

work in progress.
new idea "open hardware", you can assign MCU pins to ADC/Buttons as you like.

Great! in Leonardo board, I had to try each pin out for the Axis.

Do you have plan to add the deadzone setting in the tool?

Crosswind, not each!!

for axis use only with "ADCxx" pins (green marker).
and current version supports no more 8 axis.

Yes, yes, of cause I meant the ADC pins....

This is the result for the Channel vs Pins I got from my Leonardo board:

Axis Channel Arduino Leonardo Pin
1 ----> 5
6 ----> A2
7 ----> A1
8 ----> A0
9 ----> 4
10 ----> 12

hi boys!

here some pictures. is it easy to understand how to connect pins to pot's / buttons:

Excellent work, thanks for posting that!

g.

Very well, Thank you.

This button scheme is for connect Encoder?



Sokol1

Hi, new guy here...

Have lurked on this and other forums for quite a while, but thought I'd register just to say thanks for the MMjoy firmware - it's great and allowed me to resurrect an old CH Pro throttle with an ADB interface.



Additional buttons and rotaries, maybe a mini-stick will be added when I can work out how to add them nicely.

The only real problem I had was getting the firmware on to the Arduino, but got there first time with a USBASP programmer.

Any chance of increasing the device name to more than 10 characters?

Thanks again.

Rog99

Well done!

These gameport CH Throttles is very friendly to "update", all wires are very accessible.

Sokol1

Hi Rog99,

I want to do the same exact mod (once I get a cheap CH Pro Throttle). Well done.

For everyone else: Could someone explain why I need an extra USBasp to program the Arduino Pro Micro? According to Sparkfun, one of its features is the "On-Board micro-USB connector for programming".

If I'm right, you no longer need it.
Just the firmware, the loader an FLIP installed, i think.

But did not tested it yet.

Seems that use USB cable is a bit tricky, due restrict time to type the commands...

and since USBasp is cheap, most prefer the "easy" way.

Instructions for use USB cable and Flip (Google translated from Russian):



https://code.google.com/p/mmjoy/wiki/MMJOY2

Sokol1

Hi!
Rog99 WOW. Very good!
Lorphos NO NO NO "USBasp"!!! Use "JoyLoader" software for firmware updates.
Sokol1 Yes it encoders.

update:

thanks to Red_Yeti

Hi mega_mozg_13, you're the man!

OK, no need to buy the USBasp, instead I use JoyLoader during the 8 seconds that is it in bootloader mode, got it!

Tested today and it works as described. But had to use arduino IDE to get the right COM-Port.

First of, very, very nice job mega_mozg_13.

I'm in need of advise. I have a Leonardo, but i do not understand what the schemes are in mmjoy loader and which hex file to load to be able to support 8 axis etc. I have not found any explanation for scheme/hex void 6/36 nor YoZHeg 888. So which scheme/hex to use?

Just some more info: I downloaded the mmjoy_software[20140528_update2] and also 20140702_u1 from beta directory, but there's no leonardo option. The screenshot seems to indicate, that you used the pro micro FW for the Leonardo, is that correct? I hope there'll be a leonardo scheme/hex, if others can't be used.

Ok, i uploaded the pro micro FW to it for now. Had a little difficulties getting it programmed. So here's a little explanation for others:
1. Start MMjoy loader
2. Select scheme, crystal, and hex.
3. Go to device manager (from the device management or devmgmt-button), open ports (COM & LPT).
4. Press reset on the board, the device manager might refresh and show the com port.
5. After the 8 seconds of boot time, the com port might change, device manager refresh, as it did with me(which caused the difficulties), but you need to use the com port when in boot loader mode.
6. Type the port to port input (like COM5 for example)
7. Select bootloader type arduino
8. Press reset on the board and within the bootloader time (light doing the "heartbeat"-thing), press "upload firmware"

Also, found what the void 6/36-type is, in the wiki, MMjoy2 page, but don't know what YoZHeg 888 is.

I have a quick question, I got a digital joystick here (4 micro switches) with 4 buttons. Do I need to use the button matrix or can I just connect one button per pin directly without anything else?

No HAT?

The diode matrix is used to avoid "ghost" button press when you press three or more buttons simultaneous,
what probable you will not do.

Try using one pin from Row and one pin from Column.

Sokol1

hi to all.
mmjoy[20140909] "open hardware" release.
more inromation (russian)

hi. a have some news:


soon to release. two joysticks per one board. 8 axis/32 buttons/2 HATs per each joystick.

Hi guys, this is awesome, just what I've been looking for for a long time. Quick question. I have built a stick with 6 buttons and 5 pots, the pots are no problem, have them working on the device no problem. But the buttons are not. This is how I have them wired:



And this is the setup:



But when I press the buttons in the windows device settings nothing happens, they are not recognized. What am I doing wrong? Thanks!

Check diode orientation, on above example they are placed with strip toward ROW.

Sokol1 has right. Just swap the rows and columns in MMJoy.

Hi, new beta MMJOY2_beta_2014.10.14.rar
two joysticks for all USB 2.0 hardware (ProMicro, Arduino Leonardo/Micro, Teensy 2.0/2.0++)
more information (russian)

hi mega_mozg,
hi sokol1,

it is very nice to see you guys here.

I am excited about the new mmjoy2_beta,
so it has total 16 axis and 64 buttons?
and it only use one arduino pro micro?
is this correct?

how fast is the speed?

Tirta,

Yes, this last firmware create two "virtual" joysticks with one physical board, with 8 axis, 32 buttons each, this allows all buttons to be seen by Windows without use of keymapper's, simplifying map in games.

To be USB 2.0 the board need use ATmega32U4 like these Arduino, but you can build your own board (maybe not cost/effective if compared to Chinese ones):

https://code.google.com/p/mmjoy/wiki/MMJOY2

Sokol1

Thanks Sokol1,

However, from this picture:


at this site:
https://code.google.com/p/mmjoy/wiki/MMJOY2

I find only the old one:
6 axis (6 ADCx)
36 buttons (6 BC x 6 BR)

The new one is at mega_mozg link:
https://groups.google.com/forum/?hl=ru#!topic/mmjoy_update/Lnvn-Utj3D4

However, the connection is still not clear.
It seems that one pin is used for 2 connections?
I hope mega_mozg can clarify this.

hi to all.




for a sample see pin "A3" = [F4] AI/AE/BM it can be used as internal port ADC, OR as external SPI-ChipSelect for ADC mcp320x, OR as button matrix.
another sample see pin "TX1" = [D3] ../AE/BM there is no internal port ADC, so use as external SPI-ChipSelect for ADC mcp320x, OR as button matrix.

one pin can be used only for one function.

now only one difference between any board - is a available pins count.
Sparkfun[promicro] - total 18 pins, and 9 can be used for internal(onboard ADC) axis.
Arduino[leonardo] - total 23 pins, 11 internal axis.
Arduino[micro] - total 24 pins, 12 internal axis.
PJRC[Teensy 2.0] - total 25 pins, 12 internal axis.
JRC[Teensy 2.0 ++] - total 46 pins, 8 internal axis.

so if you want more axis, you can use SPI connected external ADC:
a) "kma200" magnetic field angle sensor + 13 bit ADC;
b) "MCP3201" 1 channel 12 bit ADC;
c) "MCP3202" 2 channels 12 bit ADC;
d) "MCP3204" 4 channels 12 bit ADC;
e) "MCP3208" 8 channels 12 bit ADC;
f) "MMSENS(MCP3202+KMZ60)" magnetic field angle sensor KMZ60 + MCP3202 12 bit ADC + trigonometric math at controller, my new project digital sensor;
SPI is a very easy to use, just connect power and ground from controller to ADC and connect SPI lines MISO/MOSI/SCK and CS(chip select). pin "CS" are individual for ADC, other pins is common for all ADC's connected.

PS: here some pictures of "MMSENS" working.

Hi mega_mozg,

Thanks for the reply.
so for pro micro, there are 18 pins.

If I use 6 for axis,
there are only 12 pins left for buttons?

so 16 axis with 64 buttons are not possible for pro micro?

Are these correct?

it is correct only if you want to use internal ADC.

but with two "mcp3208" connected to "pro micro" you can access to 16 axis(used 2 pins to "SPI-CS"), and you have 16 pins to buttons 8*8 = 64.

Hi mega_mozg,

thanks for the explanation.

do you have picture for connecting pro micro to mcp3208 to hall sensors?

look at my "ProMicro_ExtensionBoard". I use it for "Saitek x35/36". Here two mcp3208.




and special for you only promicro + mcp3208.




pins:
mcp3208.VDD = promicro.VCC
mcp3208.VREF = promicro.VCC
mcp3208.AGND = promicro.GND
mcp3208.DGND = promicro.GND
mcp3208.CLK = promicro.SCK (also "SCK" possible to share with button matrix, you can use this pin for SPI and for buttons)
mcp3208.Dout = promicro.MISO (also "MISO" possible to share with button matrix, you can use this pin for SPI and for buttons)
mcp3208.Din = promicro.MOSI (also "MOSI" possible to share with button matrix, you can use this pin for SPI and for buttons)
mcp3208.CS = any pin of promicro (this pin must used only for SPI, and it pin must be assigned at JoySetup)

and last note, if you like to use SPI and button matrix together all 3 SPI pins(MOSI/MISO/SCK) must be at one side raws or colunms. At my sample "ProMicro_ExtensionBoard" SPI shared with raws.

and connecting pot or hall to mcp3208 pins CH0-CH7, as regular ADC Pow(vcc) Gnd and out.

and guys, this SPI external ADC's you can use with any board Arduino or Teensy.

thanks mega_mozg.
I really appreciate it very much.
pictures make it very clear.

if I need only 7 axis and 42 buttons,
is 1 mcp3208 and 1 pro micro enough?

how fast is this setup compared to the first mmjoy?

Mega_mozg

I think by "how fast" Tirta mean board operations frequency, if 100, 150 MHZ, etc, relative to old ATMEGA8/16 versions.

Sokol1

hi mega_mozg,

I have looked for mcp3208 at ebay,
it seems that there are lots of versions,
here are two of them:

MCP3208-CI/P 12-bit A/D Converter IC New Microchip DIP 16
http://www.ebay.com/itm/1-PCS-MCP3208-CI...=item3a8769a5a3

MCP3208-CI/SL 12-bit A/D Converter IC New Microchip SOP-16 SMD SOP16
http://www.ebay.com/itm/1-PCS-MCP3208-CI...=item3cd878b302

which one should I use?

starting release "20140909" no more support for classic Mjoy8(atmega8) and Mjoy16(atmega16).

set "USB Poll" to "1" = 1000 Hz
2=500
4=250
and 8=125 (OS Windows limit for old mjoy8 / mjoy16).

it has many package versions:

so any of them is good to use?

"DIP" easy to solder.

thanks mega_mozg.

about the button matrix, in the new mmjoy2,
you do not specify which one is column and which one is row.

so how do you connect the buttons?

tirta
button matrix, setup as you like.

so you define which one is row and which one is column with joysetup.exe?

is there any difference between sparkfun pro micro and arduino pro micro?

http://www.ebay.com/itm/New-Pro-Micro-AT...=item20d2a4f795

or they are the same?

tirta
you eat my brain.

"mmjoy2" by default no axis and no buttons, no any fixed presets.
just setup as you like as you need.
1) open "Pins_Sparkfun[promicro].PNG" and you see a pins names(F4/D3/B6) and possible pins fuctions(AI/AE/BM).
2) think what you want, make decision, set X pins to axis, Y pins to button raw and Z pins to button column.
3) solder / setup and enjoy.

hi mega_mozg,

thanks for the explanation.

sorry I do not understand what you mean by "you eat my brain".



so if i use 8 axis with 42 buttons,
do I get faster response using mmjoy2 compared to the old mjoy16?

Tirta, x4 faster at minimum.

thanks mega_mozg,

the reason I ask for the sparkfun pro micro is the one I get from ebay:
http://www.ebay.com/itm/New-Pro-Micro-AT...i-/140972980117

does not have "sparkfun" in it.

so since I know almost nothing about electronics,
I wonder if it is the same product or not.

I have googled this, and find out that sparkfun is a brand name.
And the one from ebay is a chinese clone.

so I guess it is the same, but I am not very sure about it.

Hello.

@Mega mozg

I know its possible to use pro micros 5v to power up mcp 3208 however in your original pro micro and extension board you have used external 12v power supply converted to 5v to power up both mcp 3208.

My knowledge of electronics is limited and i can only guess why did you do that way.
Am i correct guessing that the only reason to use external power supply (stable 5v) to mcp3208 is to get highest sampling rate from the chip.

Thanks

@tirta

i am using 'ebay' pro micro and it works just fine, just make sure its pro micro and not any 'other'micro

Tirta,

This one you buy in Ebay is Chinese no brand clone of PRO-Micro (Sparkfun is only manufacturer) - work in the same way (if work... like all cheap China goods ).

Is advisable buy the in pairs... just in case.

Sokol1

hi triggahappy & sokol1,

thanks for clarifying about pro micro.
now I am going to order it

Yes it is for stable 5v.

Hi mega_mozg,

after studying and looking at your pictures and explanations, then comparing the prices at ebay:
http://www.ebay.com/itm/Leonardo-R3-Pro-...=item2ececa28e3

it seems that using arduino leonardo is better for only 6 axis & 42 buttons.

it has total 23 pins, 11 internal axis.
if I use only 6 axis, there are 17 pins left for button matrix.
so 17 is more than enough, for 42 buttons I only need 13 pins.
13 = 6+7
6 colums x 7 rows = 42 buttons.

so there is no need to add mcp3208.

is this correct?

Thanks mega_mozg

@tirta

As long as you have enough pins that long one device will do the job and you wont have to use mcp3208

I think the reason to use mcp3208 in general is not only to extend the number of axis but also to use 12bit adc instead of built in 10 bit adc.

As far as i am aware pro micro offers 10 bit internal adc (axis sensor) which offers resolution of 1024 and mcp3208 is a 12 bit adc with resolution of 4095.

thanks triggahappy.

what is the advantage using 12bit?
is it more accurate?
can you feel it when playing the game?

@tirta

That's the thing.... i don't know:P
It's only my assumption that with higher resolution you should get more precise response.
And i expect to see results while playing game.

I am rebuilding Logitech extreme 3d pro with hall sensors and belkin n52te as a throttle control with additional second pov and 2 additional axis. i need around 40 buttons and 6 axis. one way or another i need mcp3208.

I was hoping mega_mozg would shed some light on how 12bit compares to 10bit.

Since we are on the subject it would be good to know if there is significant difference in mcp3208 performance while using 4.5v instead of full 5v

Cheers

Other (theoretical) advantage is that communication between MCP3208 and the controller board is in Digital mode (binary code) instead Analog (voltage variation), what means axis less subject to external interferences (electrical/magnetic noise).

That's reminder-me that I have a old Tm F22PRO somewhere ...

hi mega_mozg,

what is the advantage using 12bit (mcp3208)?
is it more accurate compared to 10bit?

Tirta,

Probable you don't feel difference in practice, because this will be masked by joystick gimbal imperfections.

A good read about this matter (sensors) is what Milan and Slaw post in the "Battle of pedals".

Hi Sokol1,

Thanks for the link.

it seems what those guys say is mostly true,
so there is no need to use 12bit or adding mcp3208 for my purpose.

Mega_mozg, I signed up for this forum with the sole purpose of thanking you for your hard work on the mmjoy platform. I also wanted to ask you about your hall sensor and magnet arrangement. What is your usable range with the sensor/magnet orientation you use (how many steps?). I have a similar arrangement and can only get about 3000 steps

Hi, Euphoria.

What type of hall sensor you use?
By my think, 3000 steps it is very good achievement.

I purchased allegro a1324 sensors from Mouser, and my magnets are removed from tiny motors used in micro helicopter toys. They are about 5mm diameter and 15mm long, and are polarized diametrically. The hall sensor is placed at one end of the magnet with it's top facing it. I am just trying to figure out a way to get the extra ~1000 steps to get closer to full range of the MCP3208. I want to thank you again for your work. I am a stay-at-home dad and have plenty of time to tinker with projects like this.

Euphoria, I understand now.
I have test many times positions hall and magnet, and best is:

with one magnet cube(or ring);


with two flat magnets;

rotate over central pin, and minimum as possible distance between hall and magnet.

Thank you for the information, mega_mozg. Your findings are the same as my own experiments with magnet and sensor orientation. I have another question regarding rotary encoders. I have configured my encoders in mmjoy (three encoders on my throttle) and when I view the outputs thru the program "DIView", I can see the button presses registering for all three encoders. My issue is that when I turn my encoders in a game, sometimes the button presses do not register within the game. It takes sometimes 3 or 4 clicks before one button press is detected. Again, this is only while in game environment, whereas DIView sees every single click as a button press. Can you shed any light on this?

Euphoria, try to set debounce interval to minimum.

Mega_mozg,

Thank you for the reply. I have set my debounce to 1ms and still the same issue. I have done some research today that leads me to believe the issue is because of the short pulse width of the rotary encoders. Looking at the data from DIview, most of the pulses from any of my encoders last less than 20ms, more around 10-15ms. The pulses that do make it thru as a button press in game are over 40ms. I wonder if there is a way to adjust rotary encoder pulse width in the code? I will look into it some more, just wanted to share my findings with you.

Mega_Mozg - First - thanks for putting together such an incredible set of code. I've got a working Thrustmaster FCS and WCS now - for $38 total. I'm 1990s cool again, thanks to your software.

Question though - I have never been able to get the firmware loader in Joyloader to work. I've tried literally dozens of times. I have ended up flashing using the USBASP method. Would you be willing to post a YouTube Video or a walkthrough for those of us lacking the competence to make that part work?

Many thanks for all of your work!

SolderMonkey,
yes it is very very big trouble to load firmware at first time... Im searching idea to fix this.
please make more photos "Thrustmaster FCS" =)

Ok, photos. I don't have "before" shots, so some steps are missing.

I started with a $10 Thrustmaster FCS mark 1 off ebay. I think it was a Macintosh model, it had a PS2 passthrough connector on the end of it. model was KP3MACFCS.


Taking the bottom off, I removed the original circuit board. There are two ribbon cables that connect the stick to the board. I desoldered them, but I'm sure there is enough leftover to cut them at the board. There was also a 5 pin connector that would have run out to the PS2 connector and the computer, it just pulled off the board.

Remember, you're looking at the bottom of the stick. You can see the two original ribbon cables - one for the stick, one for the pots. The stick has 9 conductors and comes out of the bottom of the stick support tube in the center. The pots get 4 conductors and come in from the bottom left in this view. To connect to the PC, I just hacked a usb phone cord in two and spliced it in to the original keyboard cable, so I could keep the original stress relief. The splice is ugly, but it works.



Board views. I added one diode on the common ground and soldered the original cables straight in. The pots are just too easy, wired exactly like the common samples images earlier in this thread.






This is what the stick buttons and hat switch looked like on mine - colors all fed into the green common wire.

This is how I hooked to the pro micro.


Once again, three cheers for Mega_Mozg!

SolderMonkey, good work!!!

I save "promicro_labels.pdf" at "MMJoy/downloads" it helps with pins/ports for promicro...

i bought this on ebay
New Pro Micro ATmega32U4 5V 16MHz Replace ATmega328 Ardu.
what kind of programmer should i use?

Thanks in advance

The last firmware (Atemega32U4) is http://SimHQ.com/forum/ubbthreads.php/topics/4028164/Re:_MMJoy_-_Build_your_own_USB#Post4028164

You can load the firmware with USB cable (a bit tricky) or use USBASP cable (V 2.0).

https://code.google.com/p/mmjoy/wiki/UpdateFirmware_eng

guys, you are killing me by USBASP...

use bootloader, it easy!!!

0) connect leonardo to USB, windows ask for drivers. Use it from subfolder 'JoySetup' -> 'drivers'.
1) open "device manager" -> "LPT/COM ports". somevere will be "Arduino leonardo COMxx". warning "COMxx"!!!
2) click "reset"+"gnd" pins twice, "Arduino leonardo COMxx" - remove and windows ask for new device and drivers.
3) on "device manager" -> "LPT/COM ports". will be NEW "Arduino leonardo bootloader COMyy". warning "COMyy"!!!
!!!remember bootloader mode active only 8 sec, after leonardo automaticly reset to "Arduino leonardo"!!!
so for update firmware you need a active state "Arduino leonardo bootloader COMyy".
4) start JoySetup, manual select: chip "atmega32u4", file firmware "Firmware_lufa_[MMJOY2.ATMEGA32U4].hex", boot type "Arduino", and COM port. where "COMyy" - bootloader port number "YY".
5) again goto bootloader mode "click "reset"+"gnd" twice".
6) when field port are green it is ready to update just click "upload firmware".

Thanks to both of you.

Can the MMjoy2 work with FCC3 FSSB or other force modsof the cougar?

Bluedeath, no force feedback.

He was talking about Force Sensing, not Force Feedback.

By force mod i mean load cells / strain gauges (like FCC or FFSB or the real f16 handle) not FF.
They are direct retrofit of the cougar i was wondering if the work in the MMjoy2 too (I'm triying to ditch the origina Cougar pcb)

tensor gauge, now I understand. I do not have sensors. where to buy?

Here
Look at page 3 for the links

Thanks in advance

Bluedeath,
this is simple system like regular pot, use it as is.
or you want special features(curves) at JoySetup/Firmware?

I do not need to setup curves just ti know if the mmjoy2 works with a strain gauge modded cougar (normally i tweak curves in the simulator so is no big deal)
