Post by thread:PICSTART 16B Problem

I am unable to program a 16C84 with my picstart programmer. The symptom is that the configuration bits seem to be set wrong. Putting in a new, never used before chip, setting the device type to 16c84 and doing a read returns a configuration of Osc - LP, WDT - Off, PuT - Off, and CP - on, zeros in all memory locations, an ID of zero, and a checksum of FC00. I didn't turn on the code protect - honest. I didn't even program this chip. Trying to program the configuration bits only with XT, WDT off, PuT on, CP off, returns LP, Off, Off, and On as before. I'm using the cable supplied with the programmer, about 6' in length, and a 100 MHz 486. Switching off Turbo doesn't make any difference (but I don't know if it really changes the speed either). I still need HELP. Thanks, John-
