Docker container for esp32 development

This project is meant to ease the developmet for the esp32, containing the development tools all in one docker image, keeping your system clean.

Dependencies

That's the beauty of it, you just need docker.

Ok... If you want to use the Makefile you'll actually need make.

Instructions

Plug in your esp32 module to an USB port.

Copy your project to the project folder, and run:

make shell

in this project's top directory. The docker image will be built (if it is not built yet) and you will be presented with a bash running inside the container, from there, you'll just need to build your project.

If you don't have a project, run the make shell command and simply copy one of the examples from the example folder and start from there:

cp -r ../esp-idf/examples/get-started/hello_world/* ./

for example.

Build your project with cmake

Because of timestamps and the way make stores temporary files outside the build directory, the best way to not rebuild your entire project every time you re-launch your container is to actually use cmake. When you have a shell in the environment:

Configure the project

idf.py menuconfig

Build it

idf.py build

Flash it

idf.py -p /dev/ttyUSB0 flash
