Welp. I keep forgetting how absurd microprocessors are now. Still... That's got to be a fun soldering job. And those are 1.8v / 3v chips, whereas if you're using USB you've got 5v input.
Does it support interrupts on the pins? Or just polling?
Also, can you give me a specific example of a specific part? Searching "STM32Fx QFP208 package" gets me... a link to your comment. Great to know that HN gets crawled, but still...

(Not that there's any reason not to for a hobby project, really...)
- TheLoneWolfling 12y agoI'm still astounded that you can pick up a chip like that for <15$ (well, ok, not including shipping). Huh. Something to consider. Thanks for the links!
