i used mplab(for hex file)+ic_prog+multi-pic programmer(serial port prog;from hamradioindia.com) for programming 16f628a..
i programmed it some 30 times or so.worked fine..but now when i try to do so,it can neither read the program inside the pic(shows blank) nor can i program it(verify error).but the program inside the pic works fine when connected to a circuit(led flashes).i tried using winpic too. it says 'Vdd select failed'.also i cannot program.can anyone help me please?
