Spent a few weeks bringing up an I3C target driver for NXP MCXA in Rust/embassy. Three gotchas each took a day to diagnose and a line to fix — a 4× slow clock, a FIFO race, and a sneaky Stop that wrecked my framing. Wrote it up to make sure I never fall for these again 👇 balbi.sh/posts/i3c-ta...

I'm biased because I helped write part of it (and @balbi.sh has continued adding even more info!), but I think the `embassy-mcxa`'s DEVGUIDE is probably one of the better references now for "how embassy HALs work and how to write a good one", if that's what you're in to. github.com/embassy-rs/e...

Hi everyone, I wote a few more (personal) ideas on how I'm using Pico de Gallo for crate examples. These are personal opinions, not prescriptive in any way. balbi.sh/posts/exampl...

More metapacs, that's exactly what we need. Hopefully an embassy HAL can be built on top of this work :-) Amazing.

Write embedded drivers without the MCU in your dev loop. Pico de Gallo turns a Pi Pico 2 into a USB-attached I²C/SPI/UART/GPIO/ADC/1-Wire bridge, so your driver is just a cargo run binary talking to real silicon from your laptop. Build one for your chip → balbi.sh/posts/writin...
