What microcontollers are easy to use in a prototype?
I would like to be able to plug it right in to a breadboard.
It should also have a built-in A/D converter.
Practically all of the 8-bit PICs (10,12,16,18 series) are available in
DIP packages, and a fair number of the 16-bit (24,30,33)
Hmm; searching on Farnell ... I get 224 results for the various 8-bit
series, 12 for the PIC24 and 37 for the PIC30/33. Those are all
flash-based with ADC.
For the various Atmel chips with the same requirements (DIP, ADC, flash),
I see 57 results.
So there's no shortage of options. Choosing the right part is a matter of
the amount of RAM/ROM, clock speed, and which peripherals you need.
