INTRODUCTION
The dsPICDEM 1.1 Development Board is shipped with an example program coded
into the dsPIC device. The example program exercises several of the dsPIC30F
peripherals, such as the 12-bit 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 Development Board
hardware, refer to Section 4.

DEMONSTRATION PROGRAM OPERATION
The dsPIC30F device included with your dsPICDEM 1.1 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 Section 3.6 “Board Self-Test
3.3.1
Demonstration Code Module Summary
When power is applied to the dsPICDEM 1.1 Development Board, the LCD displays
the Demo Main Menu, as shown in Figure 3-1.
