Getting Started with Micro-Python

MicroPython is a lean and efficient implementation of the Python 3 programming language that includes a small subset of the Python standard library and is optimized to run on micro-controllers and in constrained environments. You can find out more here. You can download the firmware from this location.

For convenience, this is a link to an ESP32 binary: esp32-20180924-v1.9.4-575-g6ea6c7cc9.bin

You will need (available right here). If you are putting MicroPython on for the first time then you should first erase the entire flash using: --chip esp32 erase_flash

Program your board using the program, and put the firmware starting at address 0x1000. For example: --chip esp32 --port /dev/ttyUSB1 write_flash -z 0x1000 esp32-20180511-v1.9.4.bin
