rp2040 Temperatures

A wip project to read temperatures on a rp2040 and publish readings to mqtt.

Projects

  • cmd-cli: Send COBS encoded commands across a serial connection. Used to configure the microcontroller.
  • controller: Code running on the rp2040. Because of limitations in cargo, it is not part of the workspace.
  • mqtt-protocol: Very simple implementation of just enough of MQTT to publish data. There was no MQTT crate that compiles for the rp2040.
  • serial-comm: Implementation of a (too) simple serial protocol, leveraging COBS.

Take a look at the controller subproject to run stuff.
