[sdiy] PIC 16F1788 CPU bug

[Pete Hartman]

What I said was "While you *can* run individual AVRs and some do, it's
not the common pattern".  Clearly you're part of the "some do".  :-)
I straddle the line--I've used an AVR with the Arduino bootloader, but
not a full blown board, to port Thomas Henry's old MTS-100 MIDI to CV
circuit, back when I was starting out in all this stuff a couple years
ago.  Not hard, but not common from what I have seen.

Regarding the oscillator, I concede that I was wrong on that point...
I did say "I haven't seen" rather than "it doesn't exist". :-).

But the idea that PIC is more expensive to develop for doesn't seem to
me to be the case, even admitting that it's wrong to say you MUST
incur those higher costs for AVR/Arduino.  I can do just as
serviceable work with MPLAB X & XC8 as I can with the Arduino IDE, for
the same cost on that side of the equation.

So: AVR doesn't have to be more expensive in parts, and PIC doesn't
have to be more expensive in tools.  Where does that leave us?

Thanks

Pete
