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.

guys, a have plans to remove second joystick support again, and I need your opinion: I think more functions and supported sensors better than more axis/buttons. 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?

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. 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.

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