Step 7: Programming the Microcontroller (PIC)
Download the HEX file provided, fire up Microchip IDE or PICKit software, and program the PIC.
*Since the battery is not connected, you need to supply the power from the programmer. You can find this in the "Options" menu.
Refer to the screen shots - I recommend setting the Vdd to 4.9V, just to be sure not to let the zener diode shunt too much current. (I never had any problems using 5V so for, but better safe than sorry.)
*** UPDATE ***
The assembler source file (wave_jt-1.1.asm.zip) is uploaded. Now you can modify the firmware to modify and/or add new functions!
