BUILDING THE CODE
In this project, building the code consists of assembling the SMPS_PID_Controls.s
and isr_traps.s files to create their respective object files, SMPS_PID_Controls.o
and isr_traps.o, and then linking the object files to create the DualBuck.hex and
DualBuck.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 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 SMPS_PID_Controls.s file:
.include "p30f2020.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, as shown in Figure 3-8.
