IN-CIRCUIT DEBUGGING
The sample application program is intended to illustrate how the processor and
peripheral modules handle the functionality provided on the dsPICDEM 2 Development
Board. The MPLAB ICD 2 In-Circuit Debugger was used to program the sample
application into the dsPIC30F device. You can also use the MPLAB ICD 2 In-Circuit
Debugger to examine this baseline code to determine specific applicability to your
application.
The examination process requires that the dsPIC30F3014 device be reprogrammed to
recognize the MPLAB ICD 2 debugger rather than a programmer.
10.6.1
To change MPLAB ICD 2 from a programmer to a debugger:
1. From the Debugger menu, click Select Tool>MPLAB ICD 2 to designate the
2. Reprogram the dsPIC30F device ( Debugger>Program menu).
3. Reset the program and run it. From the Debugger menu, select Reset>Processor
Figure 10-3 shows the configuration bits for this set up.

10.6.2
After the application has been reprogrammed to use the MPLAB ICD 2 as a debugger,
you can use MPLAB IDE to run, halt and step the program. You can set breakpoints to
halt the program and examine the actual code at any point. You can also examine the
contents of the RAM and registers whenever the processor is halted.
Refer to Section 2.3 “Getting Started” for an overview of the sample application.
Flowcharts illustrate each of these processes:
• Startup and initialization
• Main loop processing
• A/D conversion processing
• External interrupt processing
The dsPICDEM 2 Development Kit/Example Software/30F3014 folder
contains fully annotated code files that you can examine, compare and copy.
