Drive SSD1327 I2C grayscale OLED with Nano RP2040 Connect (in Arduino framework), using "Adafruit SSD1327" library.


The following video show installing "Adafruit SSD1327" library in Arduino IDE 1.8.19, run on Nano RP2040 Connect (in Arduino framework) to drive my no brand 1.5" 128x128 SSD1327 I2C grayscale OLED.


The pins used for I2C on the Nano RP2040 Connect are the following:
SDA - A4
SCL - A5
(ref: https://docs.arduino.cc/tutorials/nano-rp2040-connect/rp2040-01-technical-reference)

Check using i2c_scanner, the SSD1327 OLED's I2C address is 0x3C.

boochow/MicroPython-ST7735 is a modified version of GuyCarver's ST7735.py ST7735 TFT LCD driver , for micropython-esp32. This video show steps to prepare boochow/MicroPython-ST7735 driver and font files. Tested on  Espressif ESP32-C3-DevKitM-1 running MicroPython v1.19.1, to display on  1.8 inch 128x160 ST7735 SPI TFT .
