Description

To compile the project to a firmware go into the folder where the makefile live (in the Debian WSL): ~/micropython/ports/esp32

make BOARD=GENERIC FROZEN_MANIFEST=/mnt/c/workspace_local/Python/pixelParty/pixel_party_master/manifest.py

You can write the generated "firmware.bin" from the folder ~/micropython/ports/esp32/build-GENERIC write to the ESP32 with Thonny->Extras->Optionen
