Excuse my ignorance, because I too am a beginner in the vast field of microcontrollers... I was under the impression that the low and high range of Microchip's (regular) PICmicro line were in fact similar enough to start with any (regular) pic and migrate to another without too many problems other than peripheral addressing etc changing. Is that the case or am I on another planet? I bought a book on amazon.com called "Pic in Practice" by 'D.W. Smith', that obviously mainly covers the PIC16F84 (mister popular) and some other PICmicros' that have some other functions that the PIC16F84 does not share. I my self just used the book to get started with the real basics, on the 12F629 and the 16F684 that I got with the PICstart1 kit that got given to me for my birthday. No problems at all, and with a little help from the datasheet it all seemed to work out just great. So forgive me for not seeing the problem of finding the right PICmicro to start with. IMHO just need to start on something or rather anything to atleast get the basic feel and understanding.
