Minty JDM PIC Programmer

Step 3: Schematic

Here is the schematic for circuit.  The circuit uses power from the serial port to power the PIC microcontroller during programming.  Some USB to Serial converters do not work with this circuit because of the voltage needed on the PIC's mclr pin.  This circuit works best with on board ports or serial cards.  For the ICSP pins, they are connected to the microcontroller as follows:
1.  MCLR Pin
2.  VDD Pin(s)
3.  VSS Pin(s)
4.  PGC Clock Pin
5.  PGD Data Pin
