I'm trying to choose a microcontroller for a pretty simple control system. It seems like there are about a million models available, so I'm hoping for some help in narrowing down my choices.
I've been using the Atmel AT89LP2052, which would be fine except that it doesn't have A/D---it only has a voltage comparator.
The device has to be easy to use in a prototype. I guess that means it should be available in a version that has through-hole pins 1/10 inch apart so I can insert it right into a breadboard.
It will have to read a voltage signal that varies from 0.5 to 4.5 VDC, and convert that to a digital signal of say 8 bits. Besides that it will need to handle a few discrete inputs and outputs.
It should be able to run on a single 5V supply.
It should have a good free compiler available.
Any recommendations offhand? Thanks.
