Step 3: Adding Support Files to a Project
The next step in creating a project is to add the appropriate support files to
the file
Sine_gen.pjt
.
•
In the
CCS window
, go to
Project
and then select
Add Files to
Project
.
•
In the window that appears, click on the folder next to where it says
Look In:
Browse to folder where you stored the support files created
earlier. You should be able to see the file
C6xdskinit.c
. Notice that
the
Files of type
field is
C source code.
•
Click on
C6xdskinit.c
and then click on
Open
.
•
Repeat this process two more times, adding the files
vectors_11.asm
and
C6xdsk.cmd
to the project file
Sine_gen.pjt
.
•
For field, select
Files of type
, select
asm Source Files (*.a*)
.
•
Click on
vectors_11.asm
and then click on
Open
.
•
For field, select
Files of type
, select
Linker Command File (*.cmd)
.
•
Click on
C6xdsk.cmd
and then click on
Open
. You have now created
your project file
c:\ti\myprojects\Sine_ gen.pjt
.
The C source code file contains functions for initializing the DSP and
peripherals. The
vectors
file contains information about what interrupts (if
any) will be used and gives the linker information about resetting the CPU.
This file needs to appear in the first block of program memory. The linker
command file (
C6xdsk.cmd
) tells the linker how the
vectors
file and the
internal, external, and flash memory are to be organized in memory.
In addition, it specifies what parts of the program are to be stored in
internal memory and what parts are to be stored in the external memory. In
general, the program instructions and local and global variables will be
stored in internal (random access) memory or IRAM.
Step 4: Adding Appropriate Libraries to a Project
In addition to the support files that you have been given, there are precom-
piled files from TI that need to be included with your project. For this project,
you need a run-time support library (
rts6701.lib
), which your support files
will use to run the DSK, and a
gel
(general extension language) file
(
dsk6211_6711.gel
) to initialize the DSK. The
gel
file was automatically
included when the project file
Sine_gen.pjt
was created, but the
RTS
(run-
time support) library must be included in the same manner used to include
the previous files.

Go to
Project
and then select
Add Files to Project
.
•
For
Files of type
, select
Object and Library Files (*.o*,*.l*)
.
