esp-node

Based on ESP IDF examples in the Public Domain. Uses generated MAVLink headers, under terms of MIT license.

Hardware

Developed for ESP32-S3-ETH board from Waveshare.

The ADC channels are set to 12 dB attenuation, so they accept the signal up to 2.45 V.

Building

Tested on Linux Ubuntu 24.04 with Docker:

docker run -it -v ~/workspace-local/esp32-projects:/project --device=/dev/ttyACM0 espressif/idf
cd /project/esp-node
idf.py set-target esp32s3
idf.py menuconfig  # defaults are set up for ESP32-S3-ETH already
idf.py build
idf.py flash

The log level can be adjusted in menuconfig -> "Component config" -> "Log" -> "Log level" -> "Default log verbosity".

Roadmap

• Measure sensor position with ADC
• Calibrate sensor measurement with MAVLink parameters
• Persist configuration in flash
