Before we can load the binary into the PIC24 processor we must connect the programmer to the Chameleon PIC as
shown in Figure 15.43. Notice that it requires use of the extra male right angle pin connector. This is needed to interface
the female PICkit 2 ICD interface to the female Chameleon PIC programming port.
Referring to Figure 15.43 the first step is to insert the right angle header into the PICkit 2. Next insert the complete
assembly into the 6-pin (not the 8-pin Propeller port) PIC24 programming header. When you insert the PICkit 2 into the
Chameleon PIC the PICkit 2 will not lay flush on the board, instead it will be propped up at an angle, this is fine. Make
sure the white arrow is facing away from the Propeller chip and is closer to the experimenter board region as shown in
Figure 15.43. The other end of the PICkit 2 is connected to a USB cable that is attached to any free USB port on the PC
that is running MPLAB IDE.
Now we need to tell MPLAB that we will be using the PICkit 2 as our primary programming device. To select the PICkit 2
choose the menu item located under <ProgrammerSelect ProgrammerPICkit 2> as can be seen in Figure 15.44.

NOTE
Depending on the length of the right angle header you may need to bend out the right angle
header so that instead of it being a nice 90° angle you might need it to be a 45° angle. This way
the PICkit 2 will clear the PS2 connector that it overlaps. You can bend each individual pin with a
needle nose pliers.
Also you may find it easier to reverse the right angle header so that the PICkit 2 overlaps the PIC
processor instead of the PS2 connector. When doing this make sure to turn the PICkit 2 upside
down so that the white arrow remains closest to the experimenters board area.
