A photo of a small rocket engine being test-fired on a test bench. The engine has just started to explode and is in the middle of ripping itself apart, so a huge crack is tearing it open and revealing that the inside is full of light and fire.

I expect to post about personal projects and embedded Rust stuff, not sure about work as much of it is for customers and so not really for me to post! Here's a favourite photo from this summer testing student engines though, you don't usually get to see inside a combusting combustion chamber!

Hi, new followers! πŸ™‹β€ I help run the Rust Embedded Working Group which is probably how a lot of you found me, and I do hobby electronics too. My work involves testing rocket engines, especially instrumentation and control. I'm now getting started in astrophotography too! I was @adamgreig on Twitter.

bxCAN time-triggered communication mode not supported

The time-triggered communication mode described in the reference manual is not supported. As a result,
timestamp values are not available. The TTCM bit of the CAN_MCR register must be kept cleared (time-triggered
communication mode disabled).
Workaround
None

how it started (stm32f1, 2010)
how it's going (stm32l4+, 2020)

eventually they stopped using this IP core entirely and swapped to a new FDCAN peripheral without the errata...
