Hope I have this categorized right:) If not, do let me know. I have the Olimex PG4 board, with a PIC16F84A. I'm aware that the olimex board uses the serial port for power, and it will not work with a USB to serial adapter. Unfortunately, I don't have a serial port on this computer. Is it possible to power the olimex board off of a 9v adapter while programming? Or can that only be used while the chip is running? -- Paul Anderson VE3HOP wackyvorlon@gmail.com http://www.oldschoolhacker.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
