dsPICDEM 80-PIN STARTER DEVELOPMENT BOARD DEMONSTRATION
PROGRAM
PROGRAM
The dsPICDEM 80-Pin Starter Development Board is supplied with a pre-loaded
demonstration program that exercises principal CPU functions and peripheral options
that allow interaction with the program as follows:
• Demonstrates interrupt handling by using switches S1 and S2 to blink LEDs RD4
demonstration program that exercises principal CPU functions and peripheral options
that allow interaction with the program as follows:
• Demonstrates interrupt handling by using switches S1 and S2 to blink LEDs RD4
and RD5, respectively.
• Demonstrates digital-to-analog conversion by generating an audio tone on LINE
OUT.
• Demonstrates analog-to-digital conversion by adjusting Potentiometer RP2 and
transmitting the resulting digital value to the HyperTerminal on a PC.
Refer to Chapter 3. “Demonstration Program Operation” for details on the
