In the YAP, if you set up the _CONFIG and _IDLOCS, they will be programmed into the PIC with the rest of the code. >Does someone out there have code for a pic that enables the pic to accept >text file commands from a serial port to program another pic. I have looked >at the YAPP, but would like to be able to send read, write command and also >programming parameters for various pic devices. > >Or, does anyone sell a pic that will do this? > >Or, is it possible to install a bootloader into a pics' memory, like the 68hc11? > > "If people don't know what you're doing, they don't know what you're doing wrong." - Sir Humphrey Appleby K.C.B
