Well - as mentioned, it may be best to pick "standard" parts (did you
have a preference?). This is an issue even with C or C++; many parts,
especially from STM32, are very poorly documented. In C I am still
having issues with my controller than I can only fix by copying,
verbatim, the autogenerated code. At this point I suspect order of
hardware initialization matters where no order dependency is
documented.

This is kind of sad, because most of the popular STM32 parts are
rather old. For other manufacturers the situation can be even worse.
It is also sad because I want to try various products to see which is
best (e.g. PIC32 parts are very cheap but still performant), but my
experience as far as C goes is that all development environments and
vendor provided libraries are terrible.


Also, thank you Michael, I may be able to give an update with my
progress soon. It seems wise to iron out the initialization and
hardware setup in C first.

Without much cheer,
