Hi,

The Swan can soon be programmed in Rust. The following pull-requests are still necessary:

- [Add stm32l4r5 by gauteh · Pull Request #703 · stm32-rs/stm32-rs · GitHub](https://github.com/stm32-rs/stm32-rs/pull/703)
- [Add support for stm32l4r5 by gauteh · Pull Request #292 · stm32-rs/stm32l4xx-hal · GitHub](https://github.com/stm32-rs/stm32l4xx-hal/pull/292)

with these two applied the following quick-start should work:

- [GitHub - gauteh/swan-stm32l4r5-quickstart: Rust quickstart for the Blues Swan (STM32L4R5)](https://github.com/gauteh/swan-stm32l4r5-quickstart)

for instance some [blinking and RTT printing](https://github.com/gauteh/swan-stm32l4r5-quickstart/blob/main/src/main.rs) or using [both I2C1 and I2C3](https://github.com/gauteh/swan-stm32l4r5-quickstart/blob/main/src/bin/i2c.rs), I2C3 is available without the Swan Carrier on pins A3 and D11.

The STM32L4 series already has a HAL, and it is now a matter of adapting and adding the R5 to devices to make it fully working.

You can even use RTT with the st-link probe through [probe-run](https://github.com/knurling-rs/probe-run). So if you also got the st-link from the blues shop you are ready to `cargo run` the project and watch RTT output on your machine.

([announcement tweet](https://twitter.com/gauteh/status/1497865381276434432))

I’ll post here when the pull request have been merged (hopefully). There is already a [Rust driver for the notecard](https://github.com/gauteh/notecard-rs) ([thread](https://discuss.blues.com/t/a-rust-driver-for-the-notecard/447)].

Regards, Gaute

This is awesome, @gauteh! I look forward to taking this for a spin.
