Sorry for such "noobish" question but I've tried to help my son with learning PIC programming. I load some simple asm source into MPLAB and pressed "make and program device main project". IDE build source and shot it into PIC12F629, program started, LED's were flashing as they should by source... everyone happy.
I'm an old school guy and have no idea about erasing... We tried same routine again and then we discover that we have to erase PIC to do it again?
How? (PICKIT2 programmer)
