I am trying to program a PIC 16F628 with Winpic and a JDM2 programmer. I have previously programmed this chip successfully, but this time the software just reads 3FFF back from the programmer for every memory location. With no cable attached, it reads 0000 back.
I have previously (a year or so ago) programmed the PIC successfully, but I don't have another one to try.
Is this a broken PIC or do I have something else wrong? Winpic can successfully initialise the programmer with the serial cable attached and fails (correctly) to initialise with no cable.
I generated the hex file with the CCS compiler and the only warning is that the ";16F628" comment at the bottom of test.hex is a "strange line".
