STM8 controllers

STM8 may be among the cheapest small microcontrollers. I haven't seen the use since it's easy enough to get (AVR and) ARM to cover just about any use case. I've still considered having a few just for completeness' sake. Now, that SDCC has support, it seems worth a look.

One interesting thing that this architecture might offer is the easily available debugging support (compatible with stm32 to some extent). Usable software for that is probably still missing, though.

I'll gather some notes here.



Libraries, docs

Some header files would be welcome. Libraries, maybe. It's a pretty tight fit for anything like an OS.
