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.

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.

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).

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:

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:
