well. there is a particular issue with stm32sprog which has massively hindered progress over the past few weeks.
hmmm.. I live and breathe cortex. I could help when I have spare time,
it's ok joe i got this covered.
what i _could_ do with is a review on how to use libopencm3 to do "ETR"-based timer triggering instead of "Count/Compare". (TIM8_ETR instead of say TIM2_CH2). the latency on the Count/Compare is, at the speeds this is operating at, i believe, delaying things to the point where the data lines are no longer valid. the pseudo-algorithm for this is around page 300 of the reference manual.
but i'm sure with another day or two i'll get that sorted.
