BUILDING THE CODE

In this project, building the code consists of assembling the Eg1_BlinkLed.s file to

create an object file Eg1_BlinkLed.o and then linking the object file to create the

Eg1_BlinkLed.hex

and Eg1_BlinkLed.cof output files. The HEX file contains the

data necessary to program the device, and the .cof file contains additional information

that lets you debug the code at the source code level.

Before building, there are settings required to tell MPLAB IDE where to find the include

files and to reserve space for the extra debug code when the MPLAB ICD 2 is used.

The following line is near the top of the Eg1_BlinkLed.s file:

.include "p30f6014a.inc"

This line causes a standard include file to be used. Microchip provides these files with

all the Special Function Register (SFR) labels already defined for convenience.

To build the code, select Build Options>Project from the Project menu. The Build

Options dialog displays (see Figure 2-7).
