homepage Forums Technology Flight Sim Pit Builders MMJoy/MMjoy2 - Set your own USB controller with a cheap Arduino

Hi Guys,

With the latest mmjoy, testing under Joy-tester:



I have just noticed that both my X and Y axis, even after calibration,
both of them, after a while, can not reach their maximum output.


X axis value on the Joystick axes page:
middle 2068
low 380
high 3696

Y axis value on the Joystick axes page:
middle 2057
low 216
high 3960

I am using Auto calibration with center for both axis.
And I am not moving my joystick for the first 3 seconds since I plug the USB / reset.

I am using Allegro A1302 Hall Sensor.

Do you know what is wrong here?
Is this a bug?

Icannot see the pictures but the values seem to be good for 10 bits resolution what is the problem?

the problem is:
if you look at the pictures carefully,
the value should reach the lowest and highest maximum number: 0 and 4096.

it does when I move the joystick in the beginning,
just after calibrating,


but after just a few moves,

the lowest and highest value start to diminish for some unknown reason.

If I unplug and replug the usb or restart, then calibrating it,
it is good again,
but after I move the stick some more, then the value start to diminish again.

Is this a bug?
I hope mega_mozg can clarify this.

Hi to all.

Does anybody use special functions "Stop" and "Trim" a have plans to remove it.

I do not use these functions. Thanks for all your work

BTW - The idea of these function is:

ZOOM (or ZOOM out) - when a joystick button is pressed the related axis response is divided by a choose number, reducing the in game movement, can be useful for precise set a laser over target to lock.

STOP - when a button is pressed the axis stop to respond to joystick handle movement and retain the last position, the idea maybe is useful for helicopter trim (Ka-50 Black Shark). There a issue when the button is released the axis cursor will jump for the actual joystick handle position...

Probable anyone is using this.

Good morning , again I thank Mega for their work, but I have trouble getting my arduino pro micro recognize the components.

I'm trying to mmjoy2 20150121 and for example when I connect a potentiometer (eg throttle ) Arduino promicro recognize the change of voltage but within joystick configuration in Windows does not recognize it . The same happens with connecting a button with a diode to a row and column.

I think my problem (besides my little knowledge in electronics) is not assigned the port / cannel or communes and row properly. I have looked at all the pictures I have printed the pdf with the legend does not work , you can help me .

Upload a picture of how I think the names of the connectors are assigned within the mmjoy2 :


For example if I want to connect a potentiometer as in the picture , I understand that corresponds to F4


And both mmjoy2 would have to be like this:



its ok? i dont know what happens

thanks

Pins


Labels hepls to you (print and glue to the back side "promicro")

here

also, I don't see any USB at device list.
here USB list with joystick (also keyboard and mouse)

many thanks

i´m working and i take the pictures with the promicro disconected

at home will try this

thanks again

Maybe you have write the MMjoy2 firware - what make the PRO Micro a USB HID device - but after don't define the
"joystick" (Axis, buttons, HATS, PID/VID, name...) in Configurador and "Save set to device", then un-plug
and plug again to Windows recognize and show in Control Panel - Game Devices.

IS there any suggested card to do the conversion of a ch fighterstick keeping the original matrix of the stick handle?
Thanks in advance

Any USB card will work if you "decode" how is the matrix in the stick handle, (if 4 x 5, 2 x 10, 3 x 7 ...) to hook the wires coming from handle to board lines and collumns according - this if not needed diodes, what is difficult to happen...

Or are not a firmware that recognize "PnP" the original CH matrix - like the MMJoy one that recognize the Tm Cougar/F22PRO* or Cobra M5 shifters circuit, or the Hempstick that recognize the Cougar/Warthog shifters.

I these cases (CH) I use the simple "brute force" method - Dremel the orignal PCB trials in HAT support and do my own matrix.

* Need some alteration in wires.

I would like to avoid to cut the traces and keep the original pcb by just reconnecting the cables to the newq card

This guy did what you want - plug and play the cable that coming from joystick grip - for Suncom F-15.
But do do this need developer and assembly a new PCB and firmware.

http://theseger.com/projects/2014/04/converting-old-joysticks/

I have totally rewired 2 CH joysticks.
First the Flightstick + Pro Throttle and Pedal.

then later, Combatstick, on this one I add two 4-way hat switches,
so that it becames "Fighterstick"

Also I have changed all the pots into HALL sensors.

True, it is rather time-consuming
but actually it is not that hard.
And the result is very satisfying.

@Sokol1 and Tirta, first of all thanks.

I alaready rewired (and hall modified) an f16 flcs + tqs combo, I undestand that the mmjoy is the same procedure of using a BU card, it was a lot time consuming, i'd rather avoid doing it again that way (where possible).
BTW does somenone know the color code of the F22pro/f16 flcs 5 wire cabling to compare it to the cougar one?
I've got a ch combo an TM f16 flcs an f22 pro and a tqs and a suncom F15 sfs + eagle that i d' like to convert and put in use in so i need to optimize time as much as possible.

Many thanks in advance.

new supported digital angle sensor TLE5010/TLE5011.



PCB 42mm*13mm

PCB 30mm*10mm

pros : low cost (3$) + high accuracy + minimum size + low noise + digital
cons : 6 wires interface(4 wires can shared with another SPI sensors) + need to make PCB board

Defender Combra M5 with "promicro" + TLE5010

WOW

Hi mega_mozg,

Thanks for the update.
Is this digital angle sensor TLE5010/TLE5011 better than HALL sensor?
more accurate?

@Sokol1 or anyone who knows that.
IS this the correct colo r code of the TM f16 flcs:

brown wire as +5V, green as ground, orange as clock, red as enable, and yellow as serial data out.

Is the same for the F22 pro?

@Mega mega_mozg_13 will this work with the settings used for the coufar or the VKB cobra defender pinout?

Thanks again inadvance
