I am trying to make the Sparkfun Flexible Grayscale OLED work not only on an Arduino Uno (there it works like a charm), but also on the Arduino Uno Wifi Rev2. I have understood that the Rev2 is entirely different from the Uno as it uses a different microchip and that the SPI signals are available only on the Rev2's ICSP header rather than on D11-13 as it is the case on the Uno.
So I cabled SCLK from the display to SCK (ICSP-3) and SDIN from the display to MOSI (ICSP-4). Everything else (i.e. CS, RES, GND and VIN) I left unchanged like on the Arduino Uno, also in the code.
Nothing works. Is there anything else I have to change in the wiring or in the code, especially when initializing the display?
//Initialize the display with the follow pin connections
SSD1320 flexibleOLED(10, 9); //10 = CS, 9 = RES
Or in the SSD1320_OLED.h library used for the Flexible Grayscale OLED in connection with the SPI.h library?
