Hi Karl, I wondered if you have the wiring diagram from the FMC to the Ardunio Keyestudio board?
I looked at your video but it doesn't show what pins go where on the board. I am using a circuit board as below and I'm planning to connect individual wires to the 40-pin IDE connector at the rear of the board, and then onto the Arduino board. I am aware that I will have to check each circuit line that runs back to the IDE connector, but I then don't know which wires that would go to the Arduino. Thanks, Karl.
