DCS-Bios and Arduino Nano

[Marty62]

Hi Folks

I am in the process of building the left control console for AH64 and I am having issues with the warning lights.

I am running a Leo Bodinar BU0836X switch controller which has all the switch and potentiometer from the console connected to it and this works fine as it is seen simply as a USB Joystick so to speak.

I have an Arduino Nano set up to drive the leds that are mounted in the switches to show their status.

The Nano is definitely connecting to DCS as it flashes as it should  when in game and flying 

I initially tried using the direct code reference as sown on the first page with no success then added some additional code to try and set the required digital pins as outputs

I think there are couple of issues here:

1. My Arduino Code is wrong ( most likely )

2. I cannot use only the respective LED codes without the respective switch also being written into the code

Would really appreciate some assistance in diagnosing my issue

Regards Martin

Is your port connected? You must run the bios program for the board to receive data from the game.

The code looks ok.

Check DCS bios installation in Saved Games\DCS.xxx\Scripts\DCS-BIOS

And the connect-serial-port.cmd with correct port
