It's model 96. The PC is a laptop running NT. Software is picallw. There is a hardware check built in the software for pic16's and kit number 96. attached is my asm file. I don't understand what you mean by if the address >0 Thanks. Erik ------- I assume that the programmer is a commercial one, i.e. you bought it? Usually those errors either mean there is a wiring problem somewhere (or a timing issue with software originally designed for older computers) or (if the address > 0) the hex file (or config word inside it) is wrong for the PIC you are programming. Erase/blank always appears to work (it doesn't need to verify it). I struggled with this for a while with the NOPPP (search on google for it :) until I got all the wiring sorted and delayed the program a bit. Is there any kind of test mode for your programmer device? Regards, Dennis > Thanks > > Erik -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
