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 three changes be made to the sample

application setup.

• The dsPIC30F3010 device must be reprogrammed to recognize the MPLAB ICD

2 as a debugger rather than as a programmer.

• MPLAB IDE must be reconfigured to specify the pins on the dsPIC30F3010

device to be used for debugging.

• The dsPICDEM 2 board must be physically reconfigured to ensure that it connects

the MPLAB ICD 2 debugger to the pins on the dsPIC30F2010 device that were

specified in MPLAB IDE.

The primary programming and debugging functions (PGC/EMUC, PGD/EMUD) on the

dsPIC30F device are multiplexed with other peripheral modules on the device used by

the sample application. Thus it is necessary to use an alternate pair of debugging pins

(EMUC1/EMUD1, EMUC2/EMUD2 or EMUC3/EMUD3) to examine the baseline code

provided in the sample application.

6.6.1

Setting Up MPLAB ICD 2 for Debugging

To change MPLAB ICD 2 from a programmer to a debugger:

From the

Debugger menu, click Select Tool>MPLAB ICD 2 to designate the

MPLAB ICD 2 as the debug tool in MPLAB IDE.

From the

Configure menu, select Configuration Bits... The Configuration Bits

window displays the current configuration settings for the device, as shown in

Figure 6-3.

Change the “Comm Channel Select” parameter to Use EMUC2 and EMUD2.

On the dsPICDEM 2 board, change the setting on switch S3 to turn on EMUC2

and EMUD2.

Remove any jumpers on headers H6 and H7.

Reprogram the dsPIC30F device (

Debugger>Program menu).

On the dsPICDEM 2 board, turn off M ALL on switch S2.

Reset the program and run it. From the

Debugger menu, select Reset>Processor

Reset. Then select Debugger>Run.
