MicroPython/CircuitPython, enter bootloader programmatically, without BOOT button.

MicroPython/CircuitPython, enter bootloader programmatically, without BOOT button. (Tested on Raspberry Pi Pico)


In case the Raspberry Pi Pico is flashed MicroPython: 
import machine
machine.bootloader()
In case of CircuitPython: 
import microcontroller
microcontroller.on_next_reset(microcontroller.RunMode.BOOTLOADER)
microcontroller.reset()

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 .
