I just purchased the “built and tested RGB Matrix backpack” and I am having issues connecting to it through the Arduino IDE.
I am using the USB to TTL serial converter.
Can you point me to a tutorial to make sure I have the right settings for the “Board” and “Serial Port” and “Programmer”
There is a section at the bottom of the page about programming it. All you need to do is select “Arduino Uno” as the board type. The Serial port selection should be the one for your serial converter cable (or board). The selection on my Arduino IDE for Programmer is “AVRISP mkll”, which is the default.
