Useful Commands

These are pretty specific to my setup, but with a bit of research this could work for you.

Compile and Upload Locally

With the root of this repo as the working dir:

arduino-cli compile --warnings all -t --fqbn esp8266:esp8266:d1_mini:CpuFrequency=80,UploadSpeed=921600,FlashSize=4M3M esp8266-dmx/ -p /dev/ttyUSB0 \ && ~/.arduino15/packages/esp8266/tools/esptool/0.4.9/esptool -vv -cd nodemcu -cb 921600 -cp "/dev/ttyUSB0" -ca 0x00000 -cf "esp8266-dmx/build/esp8266.esp8266.d1_mini/esp8266-dmx.ino.bin"

NOTE: The above command takes forever, waiting at Waiting for upload port.... Not sure why.

Compile and Upload OTA to Controller

With IP defined and with the root of this repo as the working dir:

arduino-cli compile --warnings all -t --fqbn sp8266:esp8266:d1_mini:CpuFrequency=80,UploadSpeed=921600,FlashSize=4M3M esp8266-dmx/ -p /dev/ttyUSB0 -t \ && util/espota.py -d -i $IP -f esp8266-dmx/build/esp8266.esp8266.d1_mini/esp8266-dmx.ino.bin

Find IP of Controller

Remotely

Requires installation of avahi-utils on Debian.

avahi-browse -ptr "_arduino._tcp" | egrep ^= | cut -d\; -f4,8,9

With Physical Access

The device prints it's IP over serial upon connection.

Monitor Serial

This requires being plugged in (duh).

screen /dev/ttyUSB0 115200

Notes

  • Install pyserial in a Python venv and run arduino-cli and arduino from it.
  • Some random async webserver stuff has to be manually installed (it's not installable through the Arduino IDE package manager)
