UBC104 Embedded Systems Typical Quote “Personally I started with PICs and have not looked into the other ones much. Motorola's 68HC family is often used for somewhat more complex tasks than PICs, but tends to be more difficult to buy. The smaller AVR's are much like the PICs in price and performance. Hence PIC-or-AVR debates tend to be very hot. There are so many 8051 clones around that it is difficult to say something in general about this family.” Quote from Wouter Olaf van Ooijen
