INTRODUCTION
A dsPIC30F DSC device shipped with the dsPICDEM? 1.1 Plus Development Board
includes a pre-programmed demonstration program. This demonstration program
exercises several of the dsPIC30F peripherals, such as the 12-bit Analog-to-Digital
Converter (ADC) and Codec interface and several of the unique CPU features. This
chapter discusses these examples and explains the functionality they demonstrate. For
detailed information on the dsPICDEM? 1.1 Plus Development Board hardware, refer

DEMONSTRATION PROGRAM OPERATION
The dsPIC30F device included with your dsPICDEM? 1.1 Plus Development Board is
programmed to automatically initiate the demonstration code when power is applied to
the board. This code is divided into two separate modules:
? Demonstration code module
? Board self-test code module
This chapter is mostly devoted to describing the demonstration program. The end of
the chapter includes a brief summary of the board self-test code module, which has
been included on the CD as a library archive only. See 3.6 “Board Self-Test Code
