[sdiy] PIC 16F1788 CPU bug

[Paul Schreiber]

PIC has a wider selection of parts, from 8-pin 8 bit up to 32bit 200MHz
DSPs, all with the same programmers and toolchain. They have DIPs to BGA.

But it always boils down to "comfort level" and support. Because PIC is
wider used, you have a larger support base.

But the advice is well given: ALWAYS check errata. For ALL the suppliers.
I've been bitten by STM ARM bugs as well. Microchip is not the only company
with silicon errata.
Ans in 99% of Microchip errata, they give a 'workaround' of the bug. But in
some cases, there isn't one and you have to find another "family member".
Also, PIC is about the best in keeping "footprint compatibility".

This is something that isn't often mentioned when AVR and PIC enthusiasts
argue.

Everything I've read on the subject suggests that Microchip's
microcontroller range is optimised for cheap devices, i.e. lower production
cost, while Atmel's is optimised for libre development tools, fewer bugs and
better doc, i.e. lower development costs.

Seeing as most of us deal with small runs or prototypes, that would make AVR
the logical choice. And yet PIC projects seem to outnumber AVR projects.

Am I missing something ?
