My exercise on  Raspberry Pi Pico 2 (RP2350) running MicroPython v1.24.0-preview.321, to display on two  128x64 SSD1315 I2C OLED (SSD1306 compatible) , and one  128x64 SSD1306 SPI OLED . The 3rd, 4th and 5th exercises display on three OLEDs as one framebuf. In the 4th and 5th exercises, groupedOLED_class is implemented, make it easier to append OLEDs at runtime. Two I2C SSD1306 OLED share the same I2C bus with different address. Connection: Exercise code: mpyPico2_tri_oled_hello.py , a simple hello world display on 3 OLED separately. """ MicroPython/Raspberry Pi Pico 2 exercise display on three OLED, 0.96" 128x64 SSD1306 OLED - two I2C OLED share one I2C with different I2C address - and one SPI OLED.

In previous I exercised on Raspberry Pi Pico 2 /MicroPython to display on I2C SSD1306 OLED and SPI SSD1306 OLED . In this post display on both I2C and SPI SSD1306 OLED. Remark: when I test the code, base on MicroPython v1.24.0-preview.321 on Raspberry Pi Pico 2 normal RP2350 and RP2350-RISCV version. It's found something strange when running on  RP2350-RISCV version. Check the video at 4:30. - The MicroPython running in a loop, without time.sleep(). - If "Stop" on Thonny IDE clicked to stop from running, the Pico 2 will disconnected, and REPL fail. - ----- Have to reboot the Pico to re-connect. It should be a MicroPython issue, not SSD1306 issue.

Last post show how to install MicroPython ssd1306 driver on Raspberry Pi Pico 2 in Thonny, and display on 0.96 inch 128x64 SSD1315 I2C OLED (SSD1306 compatible) . Here is how to using the ssd1306 driver, display on 0.96 inch 128x64 SSD1306 SPI OLED . Connection: SPI SSD1306 OLED     Raspberry Pi Pico 2 ======================================== - D/C      GP13 - RST      GP12 - SDA      GP11 (mosi) - SCL      GP10 (sck) - VCC      3V3 - GND      GND      GP9 (dummy cs) - No connection      GP8 (miso) - No connection Notice that my SPI SSD1306 OLED is 6 pins version, no cs on board. But it's required in ssd1306 driver, so I have to assign dummy GP9 for it. Also GP8 is the SPI MISO, not use in this case. Exercise Code: mpyPico2_SSD1306_spi_hello.py , a simple exercise to say Hello. """ MicroPython/Raspb...
