Hi, Can anyone suggest the simplest connection of PIC16F628A? I bought PIC16F628A to play with it and learn programming. I used one schematic but when I try to use it with PICkit3, it says: PICkit 3 detected Connecting to PICkit 3... Firmware Suite Version...... 01.26.81 Firmware type......................Midrange PICkit 3 Connected.Target Detected Target Device ID (00000000) does not match expected DeviceID (00001120). so I am not sure if the PIC is faulty or the schematic is faulty. Is 3.6V as power supply enough? Thanks L. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
