Holy &h!t! It worked!

Thank you, mega_mozg_13
Testing now...

nice update! I give it a test, and accidentally found that in the device name input, the new version can only accept 10 characters, the previous version(1119) can accept 20?

BTW, if I just want to use 5 buttons, how should I configure it? still need a button matrix? Pls help, mega_mozg_13

Thank your effort!

Yes, again 10 chars, "curves" eats a lot configuration values.


still need.best solution for few buttons

Hi,
If I understand the workings correctly you should be able to connect 1 of the BC pins to one side of all 5 switches (daisy chained), then connect the other pin on each switch to one of the BR pins (one wire for each).

That should be the simplest way of getting 5 switches working.

Hope this helps.

Does anyone have the color code for the matrix of the CH fighterstick?

You might try PM'ing 531 Ghost. He's done some very impressive mods to various CH Products devices.

Mega_mozg, I would like to thank you for all your work on the MMJoy project. Here is my contribution to the thread: my finished custom throttle for Star Citizen

Here are a couple images of the F-15 stick I reworked, also with MMjoy2






To-do list: Write up worklog for project

Nice!

I think it is safe to say that more pics, and your upcoming worklog, will be welcomed!

Euphoria, funtastic!!!
how many axis and buttons are used?


also, this is pot or encoder?

Hi Euphoria,

Wow !!
that is a very impressive throttle.

how do you make it?

Thank you for the compliments, everyone. I owe a big thanks to mega_mozg for his firmware. Without MMjoy2 I would have been forced to purchase controller boards, where I prefer to DIY anything I can.

Mega_mozg,

The F-15E Talon stick was purchased from Goodwill for very cheap. I stripped the PCB inside the handle of it's traces and rewired everything. I also replaced all the buttons with high quality snap-action switches (except for the Castle and China HAT switches). The knob you outlined in the picture is indeed a rotary encoder. The encoder itself is mounted further inside the stick, and I used a shaft from a broken potentiometer to attach. I will include more build pictures in my worklog (pending). The stick only uses two axes, but I have followed DocFlyer's hall sensor mod to perform the conversion on mine. I used Allegro A1326 hall sensors. Board used is one of your mmjoy2 designs with M32U4 AVR, and latest firmware with curves (I LOVE the curves, THANK YOU!)

The throttle started out as a lid for a VERY old metal filing box (probably from 1960-70s era). The base has something like 62 buttons all together, which I have split as two joysticks using the firmware. There are 8 toggle switches and three rotary encoders on the base. The base uses a single axis with hall sensor for the throttle slide. (I will have more pictures of the actuator when I finish the worklog). The handle is from a HORI playstation2 controller system. I also rebuilt the joystick from that kit (was my first mmjoy project.) The handle has it's own M32U4 controller built inside the box on the left side, connected with DIY USB coiled cable (making the coiled cables isn't very hard to do). The handle also has three rotary encoders. Alltogether, the throttle shows up in Windows as three controllers, every axis showing 12bit resolution (thanks to your autocalibration feature in the firmware). I will try to get my worklog drafted this week and hosted on my website.

EDIT: I forgot to mention that I also have a set of Thrustmaster RCS pedals, which I have also totally modified with toe brakes, a robust centering mechanism, and also uses MMjoy2 via M32U4 chip

EDIT #2: I also forgot to mention that the trigger is a dual-stage. It has two switches and very different feels for both actions

thanks for your great work


maybe a bug, 20150121 version on teensy2 the D0 pin for button matrix not work


and the curves apply to the raw value or calibrated value?



and two suggest

make a manual calibration setting, auto calibration always get wrong center position

more detail zoom rate between 1 to 2 (1.2 1.4 1.6 etc.

zeg33,


thanks, I check this later.


1) read raw from ADC
2) calibrate
3) invert
4) curve
5) zoom/stop/trim
6) filter(smooth)


center position watching for first 3 seconds after start work. minimum and maximum raw and correct watch always.
a have plans to do saving calibration to eeprom.


sorry, don't understand you.

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?

er... I mean the zoom divisor, minvalue is 2 now



btw

the indicator on curve setting graph is raw value

there integer value, not real. "0" or "1" have no sense, so "2" and more.


yes, this right, you a see raw value and setup correct curve for this state raw.

curve apply after calibrate and invert, so I think the graph should show calibrated value ?

in my experience even set divisor to 2 is a bit too much, allow float point value (or add a multiplier?) will be better ...

Mega_mozg, I like the idea of going back to single controller w/64 buttons. Perhaps keep the old version available for those who want more than 8 axes.

Side note: I have been writing up my worklog and will post a link to it very soon.
