The FastTrack PIC circuit board can either be used with "Raw" 12F629 /12F675 PICs or Genie/PICAXE 08 / 08M2 "Bootstrapped" PICs.
(For correct operation, please note, PICAXE/Genie devices require an additional 10K resistor to be connected between I.C.legs 2 and 8.)
PROGRAMMING PINS:
Pin 0 (I.C. leg 7) - Output Pin
Pin 1 (I.C. leg 6) -
Input: Analogue or Digital Pin (from input stage of the FastTrack pcb)
Pin 2 (I.C. leg 5) - Digital Input or Output Pin
Pin 3 (I.C. leg 4) - Digital Input Pin
Pin 4 (I.C. leg 3) - Output Pin (to transistor buffer and output stage(s) of the FastTrack pcb)
If Pins 0,2 are used as outputs: Connect components via a 1K series resistor and make the PIC's R value = 220 Ohms to obtain up to 18mA from the zener supply. The black square dot on the circuit board indicates the position of I.C. leg 1.
