ItsyBitsy and OLED problem

by crimsonchain on Sun Jul 05, 2020 12:06 pm

I'm trying to get the sample code for an OLED working. I'm using the Adafruit ItsyBitsy 32u4 - 3V 8MHz board and a Monochrome 1.3" 128x64 OLED graphic display - STEMMA QT / Qwiic. I also have the lipo back pack on it if that makes a difference.

The problem I am having is the screen will show the Adafruit logo for half a second then go blank.
The example code, ssd1306_128x64_spi, is stock except for some pin changes

Code: Select all | TOGGLE FULL SIZE
#define OLED_MOSI   MOSI
#define OLED_CLK    SCK
#define OLED_DC     MISO
#define OLED_CS     12
#define OLED_RESET  13


Some one please tell me where my dumb is located so I can sort it out.
