- Standard Microchip ICSP Port to re-programmed the PICJazz 20PIN board using Microchip PICkit2 programmer
- Example project using PICJazz 20PIN board could be found on http://www.ermicro.com/blog
- The PICJazz 20PIN board demo program source code is include in the CDROM; this program demonstrate the capability of the PICJazz 20PIN board such as accessing the RS232 port, using the user switch, using the user analog input (trimport) and running the four 3mm blue LED.
Running the PICJazz 20PIN demonstration program
The PICJazz 20PIN Board comes preprogrammed with a demonstration program (PICJazz16F690Demo.c). To use this program, connect the PICJazz 20PIN to the battery power that comes with the board. The demo program will display the chasing light on the four blue LED (mode 0). Rotate the user trimport, labeled VR, and the chasing LED speed will change in different rate. Press the user switch, labeled S2, and now the board will blink all the LED (mode 1). Press this user switch once again will bring you to the number guessing game through the RS232 port (mode 2).
