Hi All -
I've got a PIC16F887 wired up to a programming circuit with a parallel port interface to a computer running Windows XP.
I've written some basic programming software and a hex -> PIC serial command parser and am 95.01% confident that it's working correctly.
I'm having problems sending the correct sequence of commands to the PIC to be able to read/write program and/or other memory. I believe my attempts to write the Configuration register to disable code protection at 0x2007 have failed.
Does anybody have experience programming this chip manually who would be able to advise/consult me?
This is mainly an exercise for myself to show that I can get this to work (aka 'for fun').
