2.5.3

Build the Project

Select

Project>Build All.

Observe the progress of the build in the Output window.

When BUILD SUCCEEDED displays you are ready to program the device.

Program the dsPIC30F4011device (

Programmer>Program)

2.5.4

Run the Application

From the

Programmer menu, select Release from Reset to enable code

exectution

On the board, turn off the M ALL switch in S2.

As the code begins executing, note that the operation is identical to what you

observed out-of-the-box (see Section 2.4.3 “Observe Sample Application”)

2.6

IN-CIRCUIT DEBUGGING PROCESS

MPLAB IDE lets you run, halt and step the program. It lets you set breakpoints to

examine the code at specific locations or on occurrence of specific events. It also lets

you examine the contents of the RAM and registers. The MPLAB ICD 2 allows you to

run the application on the dsPICDEM 2 while monitoring it in MPLAB IDE on your PC.

The examination process requires that three changes be made to the sample

application setup.

• The dsPIC30F4011 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 dsPIC30F 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 dsPIC30F device that were

specified in MPLAB IDE.

2.6.1

Select MPLAB ICD 2 as Debugger

To change MPLAB ICD 2 from a programmer to a debugger for a dsPIC30F4011

device:

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 2-7.

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.

Program 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.

Note:

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.
