A 4x4 switch matrix is connected to PORT0. Bits 0-3 are programmed as input while bits 4-7 are programmed as output and programmed LOW. Bits 0-3 read HIGH because of internal pull up resistors. Eight LEDs are connected to PORT1 to display the status of PORT0. They will display the ...
If you want to create a ONE panel matrix with an arbitrary resolution, use theintegration/ArduinoFw/tpm2serialfirmware If you want to create multiple 8x8 panels, use theintegration/ArduinoFw/pixelinvaders/neoLedWS2801Spifirmware. This firmware is based on the fastspi2 library and can handle diff...
