F2837xD C-Code Header Files

TMS320F2837xD Microcontroller Workshop - Peripherial Registers Header Files 3 - 13

three steps needed to use the header files. The first step is to include this file directly or indirectly

in each source files.

Global Variable Definitions File

With F2837xD_GlobalVariableDefs.c included in the project all the needed variable definitions are

globally defined.

Global Variable Definitions File

F2837xD_GlobalVariableDefs.c

 Declares a global instantiation of the structure

for each peripheral

 Each structure is placed in its own section using

a DATA_SECTION pragma to allow linking to the

correct memory (see next slide)

 Add this file to your CCS project:

F2837xD_GlobalVariableDefs.c

#include "F2837xD_device.h"

…

#pragma DATA_SECTION(EPwm1Regs,“EPwm1RegsFile");

volatile struct EPWM_REGS EPwm1Regs;

…

F2837xD_GlobalVariableDefs.c

The global variable definition file declares a global instantiation of the structure for each

peripheral. Each structure is placed in its own section using a DATA_SECTION pragma to allow

linking to the correct memory. The second step for using the header files is to add

F2837xD_GlobalVariableDefs.c file to your project.
