Dockerized Arduino IDE for ESP32

This is a Dockerfile for running the Arduino IDE in Linux with the ESP32 core installed as well.

I was trying to compile / run Arduino programs for ESP32 on Linux (Ubuntu), but I kept on running into issues.

I also tried using the Arduino CLI, but that was broken for the ESP32:

• arduino/arduino-cli#1450 (comment)

This Dockerfile makes it easy to run the Arduino IDE & upload programs to the ESP32.

Build the image with:

   docker build . -t esp32:latest

And run it with ./run.sh

Your board needs to be plugged in.

Further Instructions

Once the IDE is launched:

• Select "Tools > Board > ESP32 Dev Module"
• Select the right port (/dev/tty/USB0) in "Tools > Port"
• According to UMass CICS256, you should change the upload rate to 460800
  • Not sure if this is only for the board provided in CICS256
