Usage

If you are not using a picoprobe

1. make release
2. Plug in Pico
3. cp build/release /run/media/$USER/RPI-RP2/

With picoprobe

To debug and load software via openocd

• build and install openocd from source
  • For Fedora users, run setup/build_install_openocd.sh
• Debian/Ubuntu users
  • See the Getting started with Raspberry Pi Pico for directions to build and install openocd
    

See this guide to run openocd without Root privileges

TODO

1. Configure build tags to enable/disable unused packages as needed
2. Add anemometer support

• Requires multicore support to monitor two interrupts at the same time.
  I'm looking into using the C/C++ SDK's multicore APIs and CGO to use 2nd core
  See Tinygo issue 2446

3. Setup receiver repository to store and transmit data

Inspiration

• My desire to learn more about embedded electronics and Go
