Use your Esp32 to play and control music from a bluetooth audio source.

• Esp32: either use a dev kit or design your pcb (mine will come soon!)
• KY-040 rotary encoder
• ILI9488 3.5" TFT display. There's 2 version of this display: with and without touch screen. This project does not use the touch screen.

The project is still in progress, but this is what it looks like so far:

Instal the Expressif IDF framework or just make your life easier and just use the espressif/idf docker image.

docker run --rm -v $PWD:/project -w /project -u $UID -e HOME=/tmp -it espressif/idf idf.py set-target esp32

docker run --rm -v $PWD:/project -w /project -u $UID -e HOME=/tmp -it espressif/idf idf.py menuconfig

In this step you can choose your configuration, like the preferred pinout. For the default configuration and pinout look below.

docker run --rm -v $PWD:/project -w /project -u $UID -e HOME=/tmp -it espressif/idf idf.py build

docker run --rm -v $PWD:/project -w /project -e HOME=/tmp --privileged -it espressif/idf idf.py -p /dev/ttyUSB0 flash monitor

Note: you need to give the container permission to access the Esp device.
