yes.
Which button column and Which button row?
tanks for your answer.

Is OK, but in this arrange will result in ~185x45 mm board, difficult to fit inside a "joystick":

Here a more compact 6x6 matrix: 94x40 mm - PCB easy to do with toner method (1 mm trails) and less bridges (blue):

Yes, if want I can send the files (.PDF) for Laser print, or Gerber files to order the PCB in some online shop.*

Laser metod - or better "Toner transfer method" is: https://www.youtube.com/watch?v=bk6WJpGyc4I

* Can be the fast and cheaper option, e.g.if you dont have all tools needed do make the PCB, e.g. 0,8mm drill for make holes, a Dremel... bu less fun.

I use Sprint Layout, simple but easy.

This USB controller, the MJoy8 - "Gran Papa" of MMJoy2, I DIY with toner transfer method.

In the picture are receiving firmware.

But try draw with Fritzing, they have PCB make service: http://fritzing.org/services/

You find several others online, and very cheap ones in China.



Yes, but are penalty in board size, thehe above matrix with pins for fit a Arduino PRO Micro, increase the board size considerable:

You can save some space using double side layout, but this add complication to draw and specially for make - not impossible but much more difficult for DIY.

If size is issue, there option to use Shift Register board with CD4021B instead matrix, each handle 8 buttons connection, fo 32 buttons will be needed four.

The guy sold this boards ready to use, if I understand correct one board include all options.

BTW - In this drawing how wire a matrix (4x2) without use PCB.

LOL. MMJOy2 "pirate".

Including CD4021 Shift Register board and TLE5010.

The matrix looks OK, for TLE5010 plug you need connection for SCK pin.

Teensy++2.0 support with 6x6 matrix - 105x58 mm:

EDIT - See revised layout below.

Highlighted connection for analog axis (up) and TLE5010/11 (down) - not sure about this connection (if SPI-CS is MOSI?)...

Based on this text, shared connections for TLE5010/11

GEN
MISO
SCK
Gnd
+5V

Individual (F4, 5....) pins - that can be used for analog axis input.

CS

In the above arrange you can connect analog axis in 3 pins from left.
Or digital (TLE5010/11) using all 6 pins - if pins used in Teensy++2.0 are correct.



The pins header and diode in the above matrix, diode can be assembled on vertical (bellow) - or used SMD diode, or horizontal (up), or combine both options - for this need change in layout (not finished).
Blue are bridge on back side of board. All this optimized for DIY methods. For double layer, SMD, the layout can be more compact.

Edit - Think that now are correct:

Is a resistor (1k), for replace the 5 eliminated in TLE5010 board.
But if you get TLE5010 board assembled with resistors, dont need add this in matrix.

OK, can be used diode and resistor SMD (0805) or pass through:



BTW - I try drawing with Fritizing, but this thing is PITA! In Sprint Layout is like draw in MS Paint.

Looks OK and compact. Just invert the matrix pins vertically or the USB cable end above some pins connection.

Good idea in use diodes as jumpers, save some solder.

Cooper background fill is good for DIY, because mean less area to corrode.

For make in PCB shop don't matter - and some can optimize the layout before make.

Yes, now make or order - draw this is addictive, you can end wasting time drawing and not building (me).

Based on this drawing for encoder diode are pointed for pins (contrary for buttons):

A bit confuse what are row and what are column in the drawing - seems "to the next..." are inverted.

Hi all,

I have set up a Pro micro with an 8x8 button matrix (not all connected yet) and when I press the button it is also recognized by MMJoy2 (numbers turn red in the tool).
Where I now have the problem is to do use it in a game (DCS/War Thunder). Do I have to assign a "Key" to each button (in the field "H/W button") or should it be recognized as Vjoy_btn_xyz?

Btw: Great work so far!

8x8 matrix = 64 buttons

Windows and games see only 32 (DInput limit).

In Windows Game Controler (type: joy.cpl in start box) you should see and test the buttons up to 32.

For butons above #32 you need use keymapper (press button to send key press for games), eg. Joy2Key, XPadder, SVMapper, Autohotkey...

Thanks everyone!
Thanks to this forum I built a throttle with 20 buttons using a pro-micro and MMjoy2.

I'm not going to upload pictures, though, because those are my frist weldings

Edit

Troll,

I think you can find the answer with practical tests.

Cariddi,

That post need pictures.

Yes, the first time is need install the COM drivers - for the next MMJoy2's is not needed.

Help tick the field "Auto-start upload firmware when COM port is active" due the 8 seconds that this port remain open.

Hello everyone. I have a question, I will redesign the joystick and thought was put into one of the sticks a dial axis as the link:

http://es.aliexpress.com/item/Free-Shipping-2PCS-LOT-Dual-axis-XY-Joystick-Module/2016825722.html

And use the axis as buttons. Mmjoy recognizes me well, I assign axis 1 and 2 and in the section axis button to select these axes. My question is on the percentage to be put?.

If you are referring to "Axis to button" and assuming that you goal is use this mini-stick as 4 way "HAT".

Try - for example - 0 to 45% of axis X press button 1 and 55 to 100% press button 2.

The 45 and 55% value will define how much is need move the mini-stick for press the button. Test with different values.

Same in Y axis.

Sorry is axis to button (the traslator software) i try with 0%-40% 60%-100% but the button is like always press. i think that maybe select the button like encoder? not?

Many thanks
