MicroPython/ESP32-C3 + 1.8" 128x160 TFT ST7735 SPI, using boochow/MicroPython-ST7735 library.

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.

    Hi, do you know if the pin connection is the same for ESP32-S3-DevKitC-1U?
