Hi mega_mozg

Thanks for updating mmjoy2 with curves.

However, I am rather confused in setting it.
Can you give me some direction?

With hall sensor, it seems that my center is not really the center.

This is my center (vertical black line):

Can I move it slightly to the left, so it can be really centered?


this is my extreme left position:



and my extreme right position:


As you can see my left/right extreme positions are still somewhere in the middle,
can I move it to the edge?

And there are zoom, stop, trim, divisor, and reduction.
What number should I put in it?

And there are DZ low, center, high, dynamical.
What are these for?

Please advise.

PS. for me, 8 axis, 4 hats, 64 buttons is enough.

Tirta, try setting Auto Calibration to without center and try again. This worked for me

Tirta zoom, stop, trim are not additional parameters for the accuracy of the axis.
This are special functions which you can map to a button. The stop function would ignore the movement of the axis as along as the button is pressed.

one controller - one joystick - 8 axis, 4 hats, 64 buttons?



I would like to use 9 axis, would you be able to leave an old version available to do that?

Hi Euphoria & Red_Yeti,

Thanks for the replies.

The most important thing that I would like to know is how to really center my center.
The curve will be useless if my joystick center position is not in the center.

I hope mega_mozg can explain how to do it,
since this feature has not been explained in the readme.

Auto Calibration with center helps to you. when you connect to USB first 3 seconds DONT MOVE stick - firmware watch for "center" position.

use old(current) version without updates as long as you wish =)

Thanks mega_mozg.
I will try it.

Is DZ dead zone?
what is dynamical DZ?

Is it possible to set up MMJoy for collective controls with 2 sticks? This is how I want the controls to end up:



If MMJoy can't be set up like that, I'm planning on getting another arduino to change the signals.

Mechanically link the controls. That's how it's done in the real thing. smile

I think doing it in SW would be a lot simpler, and leave room for my legs between the sticks...

You're not going to be able to do it in software at all - not realistically.

The cyclic and anti-torque pedals should be interconnected under the cockpit floor. The collective can share a common axle that runs behind the seats. A little magic with some bevel gears will even sync the twist throttle on the collective if that's how your sim is configured.

I'm using hall effect sensors, so it would be as easy as averaging the voltages to get pitch and taking the difference to get yaw. I'd just have to rescale the pitch/yaw ranges because yaw would eat into my range for pitch or vice versa. same way for roll and heave. I've heard it's easy to set up with TARGET, but I've only got the arduinos.

You'll be better off in the long run tying the controls mechanically.

Yes I agree with that.Plus having mechanical means you can have the pots in a lot more convenient place for maintenance instead of diving head first into the middle of the pit.

Hello

First of all congratulations to MEGA_Mogz by Mmjoy project that I find amazing , I 'm hoping reach parts order online to start my project to make my own HOTAS joystick.

But I have several questions: between the buttons I've gotten have some illuminated with a small led inside, for push buttons i want to leave the led always on, but for switches would it be possible that Mmjoy configurator can on or off the led when press the button? As this affect the button matrix?.

My other question is about the analog axes , i thought to use potentiometer for the four axes that I want, but in the pictures I've seen that most people use hall sensors are they better ? more accurate maybe? ¿ they consume more than 5 V usb provide?

Thanks for this post which is being helpful.

MMJoy LED controller is not for illuminate switch's, but for game output, eg monitor if landing gear is down, and depend on game output (so will work in some, not in others).

To use LED on you project, due limitation on USB cable amperage the ideal wold by use a independent power source for LED's, so the illuminated LED's can be always on (and toggled off if desired), and for toggle switchs if you use DPDT (duple circuit switch) switchs, one pole send the command for game, other turn on/off the LED.

You can use potentiometers in you project, there's not wrong with then - IF are good quality ones (what joysticks manufactures rarely use, so the potentiometers joystick "bad" fame).

CONS - Good potentiometers will cost more than DIY HALL sensors assembly* (look at Bourns, Spectrol, Alps... prices).

Probable you dont find for buy potentiometers with 60 degrees turn range used in joysticks (are custom made for joystick manufactures), most of you find is 270 degrees, this limit axis theoretical resolution because if you dont turn the potentiometer the expected 270 degrees you dont varies the voltage from 0 to 5 volts.

You can use gears to turn more the pot', but this make the assembly complicated and induce backslash.

Potentiometers wear with use and start cause spikes (The "high end" - at time - Cougar or G-940 can tell the history).

HALL (of similar sensor) advantages is his low cost cost* and easiness for use the axis full resolution (or varies from 0 to 5 volts).

CONS - Difficult to set the middle position relative to magnets due the his low size, making DIY assembly trickly.

* Low cost for sensor only - HALL sensor assembled like potentiometer, e.g. the ones used in automotive industry is expensive (~80$).

Many thanks Sokol1

Upon receipt of all materials shall begin testing, I have thought several Alps potentiometers used in the throttle or rudder , the issue of concern led me less , now I 'm circling like making structure for the x and y axes

Hi Guys,

After using arduino leonardo for only about 3 months with no problem,
suddenly yesterday I found some of my joystick buttons do not work,
after further examination, I find the culprit is pin D0,
all the buttons that connected to this pin do not work.

first I thought might be bad connection or broken wires,
but I can not find it.

then I substitute D0 with another pin,
all the buttons work again.

so there must be something broken with this pin,
however, I can not find it.

I guess the quality of these arduino leonardo - chinese clone is not very good.
Anybody has similar experiences?

latest version bug report for mega_mozg:

your bootloader button on your joysetup.exe does not work,

I have to use reset button on the arduino board,
or connect "reset" pin and "ground" pin
to get to bootloader.

but this works only if I use win7,
with xp I can not get to bootloader,
no matter how many times I press the reset button.
