Steps to setup library on Arduino IDE, to display on 1.12" 128x128 SH1107 SPI OLED with RP2040. Tested on WeAct RP2040 (16MB) . Run example, using suitable constructor and run. Library: Install U8g2 in Arduino IDE Library Manager.  U8g2 is a library for monochrome displays, version 2. Connection: Raspberry Pi Pico pre-defines SPI pins in Arduino are: SPI_MOSI:      19 SPI_MISO:      16 (not use) SPI_SCK:         18 Connection between RP2040 and SH1107 SPI OLED SH1107 RP2040 ================== GND GND VCC 3V3 SCL GP18 SDA GP19 RES GP20 DC GP21 CS GP22 Example: Open Examples > U8g2 > full_buffer > GraphicsTest In my test, Use one of the constructors: U8G2_SH1107_PIMORONI_128X128_F_4W_HW_SPI u8g2(U8G2_R0, /* cs=*/ 22, /* dc=*/ 21, /* reset=*/ 20); //U8G2_SH1107_SEEED_128X128_F_4W_HW_SPI u8g2(U8G2_R0, /* cs=*/ 22, /* dc=*/ 21, /* reset=*/...
