This is the 12th changelog for Knurling-rs, our push to sustainably build better tooling for developing and debugging Rust software for embedded systems. Knurling-rs includes a suite of tools that make it easier to develop, log, debug, and test your embedded Rust libraries and applications!

Knurling-rs is supported by our sponsors on GitHub. If you're interested in seeing more projects like this, consider becoming a sponsor today!

New knurling-sessions content

Since the last changelog we have added content covering how to display CO2 sensor data on the ePaper display.

Sponsors can check the new content in the Display Sensor Data section of knurling-books (check this sponsors dashboard thread for credentials and discussions)

Community

In this section, we highlight some community work to integrate knurling crates and content in other parts of the Rust ecosystem.

• Matt ported the air monitor we have been developing in the knurling-sessions from the reference nRF52840 development board to a STM32F401 dev board.

Great job Matt!
