esp32-micropython-image-builder

Build ESP32 Micropython images with your custom code included

This repository creates two separate images:

• stable - this image is built from the most recently tagged release of MicroPython
• unstable - this image is built from the tip of the master MicroPython repository

Example Code

• Create a Dockerfile alongside your code to copy your file(s) into the image:

FROM dcmorton/esp32-micropython-image-builder:stable

COPY main.py ${MICROPYTHON}/ports/esp32/modules

WORKDIR ${MICROPYTHON}/ports/esp32

ENTRYPOINT ["make", "PYTHON=python"]

• Build the image from the Dockerfile

$ docker build -t esp32-image .

• Run docker container with above docker image

docker run -v $PWD/output:/data/micropython/ports/esp32/build-GENERIC/ esp32-image

• The firmware file will be in $PWD/output/firmware.bin.

More Examples

The esp32-dht22-upython project uses a similar Dockerfile and GitHub Action to build a firmware image and upload the image to AWS S3.
