The link is to an online book which is pretty cool and the target processor isn't far off (stm32f3 but my hardware guy prefers kinetis for some reason, at least we're in the same cortex land). Timely in that I was looking at a couple of weeks downtime with the new year and perhaps this can fill it productively although I'm only guardedly optimistic: It's going to be hard to supplant the nice build environment I get in the IAR product
I’ll switch to Rust for embedded once there’s a really solid USB stack. UART don’t cut it no more for talking to a computer. Seems to be in the works though!
