You call 120MHz lowly? I call that luxury! I am working on a product where we're running an M4 way below 1MHz. And our hardware guys have me counting bytes in software...
FreeRTOS is a pretty good fit for this situation. I am only disappointed that newlib is so ridiculously huge in comparison. Some functions in there are twice the size of FreeRTOS.
- joezydeco 9y agoI typically wouldn't, since I grew up working on 1MHz 8-bit cores. But working with some of these tiny M0 and M3s, there's nothing slower than 60-120MHz now.
- gmueckl 9y agoWell, these parts can almost always go much slower than that if you need to save power. Our hardware engineers want to because they reall, really, really do not want to provide the extra few uA for an extra half MHz or a few extra bytes of Flash. Which means I am stuck counting bytes and cycles like it is 1980 all over again. Not saying this isn't fun, but don't tell my boss ;).
