Arduino Mega switch matrix DCS BIOS

[filthymanc]

Hi all,

I am in the process of building a switch panel for the FA-18. I've got all the bits and pieces and am trying to understand what I need to do to get it working.

 

I want 60 switch/button inputs, and want to do it on 3 matrix 4 columns 5 rows.

 

I tried to test this on a smaller scale and realised that I can't even get a simple matrix to work.

I've been referring to the DCS BIOS control reference page, and see the matrix2pos/3pos commands.

 

I've totally confused myself and would love it if someone could point me in the right direction.

 

This is my first attempt at anything like this and I don't want to give up!

Also, I'm using Arduino Mega, breadboard, diodes, switches and pushbuttons.

I've planned my circuit and I know what switches I want where on matrix.
