Understood, though it's $10+ in singles,
while the LPC1756 is $8.40 in
singles and the price drops faster in 100s than for the AVR.
64tqfp versus 80tqfp.
the onboard EEPROM on the 647 (for custom keyboard mappings) makes
life interesting, though.
Oh, I like ARMs too. :) But I thought we were
looking for an 8-
bit solution. My mistake. If you don't mind single-sourcing, a
PIC32MX2 might also be worth a glance. from AVR32 and PIC32 and such in favor of ARM. In the
spirit of Tony's
philosophy on having all the material on hand to fix things, I
think the
AVR32/PIC32/etc. uCs are too niche. ARM is all over the place, and the
likelihood that one could get a compiler and a programmer 10 years from
now on ARM is probably better than for some of the other families.
So how many of these things do you plan to put out? I can't imagine
that there's a huge market in keyboard-to-vintage PC converters.
Mainly I am
interested in the CBM tangent, and you'd be surprised how
many people want a PC KB on their C64/C128. But, it looks like a small
design could be re-purposed to handle lots of options.
