Reposting with [PIC] tag so more people will see it. ----- Original Message ----- From: "Ken Ouellette" hello, I just bought the easyProg board from http://www.embedinc.com/easyprog/ I bought the PCB board from thm and ordered the parts form digikey but I had many parts here. The circuit voltage seems to corespond to the data sheets of embedinc. My problem is the oscillation, I and no 20Mhz oscillation. I took the chip Pic16F648 and put itin a bread board with a 20Mhz crystal, capacitor and I still dont get any oscillation. 1- Do I need to program that chip? 2- Is oscillation from that Pic necessesary to burn a chip ? thank you Ken -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
