Thermal Camera 2 (tc2) agent P2

This is designed to be a drop-in replacement for leptond on Cacophony Project 'classic' thermal cameras. It runs on the newer 'Thermal Camera 2' hardware, and is responsible for connecting to the rp2040 CPU via SPI and reading off frames provided from the attached flir lepton module. Gathered frames are then output to either a unix domain socket on the Raspberry pi, from which they are picked up by the thermal-recorder process – or, in development mode, frames can be output via TCP socket over wifi to a local development computer for debugging purposes.

Install dependencies

rustup target add aarch64-unknown-linux-musl sudo apt-get install gcc-aarch64-linux-gnu

Build and deploy

1. Edit deploy.sh to specify the name of your development raspberry pi on your local network.
2. Run deploy.sh

Making release with updated firmware

• In tc2-firmware you will first need to.
  • Increase by 1 the FIRMWARE_VERSION in src/main.rs.
  • Merge that then make a new release.
• Back in the tc2-agent repo, update RP2040_FIRMWARE_VERSION in .github/workflows/release.yaml to match the new github release version.
• Update EXPECTED_RP2040_FIRMWARE_VERSION in src/main.rs to the new firmware version.
• Now when making a release it will grab the new firmware and pack that into the .deb file so the RP2040 can be programmed.
