I bought both Monochrome 0.96" 128x64 OLED graphic display PID: 326 and Monochrome 128x32 I2C OLED graphic display PID: 931, I plug in power and I get nothing. I have verified 5v on 326 and 3.3v on 921.I have also loaded sample software and nothing. Any advice?
UPDATE; I was able to get the 128x32 I2C OLED to work.
Do I need to change other code to get the 128x64 SPI to work? I already changed the header to #define SSD1306_128_64
