Does anyone know where the protocol for communicating between the PICStart and MPLAB via the serial port may be found? I've looked all over the Mchp site, and elsewhere. Is this considered to be proprietary information by Microchip? I can only find one PIC programmer, that from Newfound Electronics, that claims to be "MPLAB-compatible". Did they need a special dispensation from on high for their design? - Dan Michaels Oricom Technologies http://www.sni.net/~oricom ==========================
