I have a setup with two RA8875 on an Arduino Mega that is working very well. However - and I hardly dare writing it: as soon as I connect a third RA8875 to the setup (again: same SCK/MISO/MOSI as on the other two, separate CS/RST), I run into the same problem ... the initialization fails ... RA8875 not found.
Has anyone encountered that as well?
Does anyone have an explanation?
