Install esptool on Windows 11


esptool is a Python-based, open-source, platform-independent utility to communicate with the ROM bootloader in Espressif chips; such ESP32, ESP32-C3, ESP32-S2, ESP32-S3...

To install esptool, Python and pip is needed, read Install Python 3 and Thonny IDE 4 on Windows 11.

To install esptool:
pip install esptool

Once esptool is installed, you can update it with:
pip install esptool --upgrade

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 .
