Phew, just updated the firmware on the PCB, everything went fine. Next stupid question: how do I configure Gamepad Mode? If I try to bind the inputs in Emulation Station it says “Gamepad detected”, however if I hit a Button to configure the controls the picade is still recognized as a keyboard. I guess I have to transmit your serial config string, what´s the best way to do that? I fiddled about with the arduino IDE and found a function “serial monitor”. Just send the string via the IDE to the PCB? Or should I use the Python script mentioned at New 2.x Configurable Keyboard/Gamepad Firmware ? Sorry for the questions, but this is Python / Arduino is terra incognita to me and I don´t want to brick the PCB ;-) …
