For what it's worth I have just built a ATmega16-16PI development board on stripboard. I have a 12MHz crystal with the terminals 0.2 and 0.4 inches from their MCU pins and the capacitors 0.6 and 0.7 inches out from the MCU. It runs fine. -- Richard Urwin _______________________________________________ AVR-chat mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/avr-chat
