Note that all the folders containing the programs and support files in the accom-
panying topic CD should be transferred to the subdirectory
myprojects
. Change
the properties of all the files included so that they are not read-only (all the folders
can be highlighted to change the properties of their contents at once).
1.3.2 Useful Types of Files
You will be working with a number of files with different extensions. They include:
1.
file.pjt:
to create and build a project named file
2.
file.c:
C source program
3.
file.asm:
assembly source program created by the user, by the C compiler,
or by the linear optimizer
4.
file.sa:
linear assembly source program. The linear optimizer uses
file.sa
as input to produce an assembly program
file.asm
5.
file.h:
header support file
6.
file.lib:
library file,
such as the run-time support library file
rts6700.lib
7.
file.cmd:
linker command file that maps sections to memory
8.
file.obj:
object file created by the assembler
9.
file.out:
executable file created by the linker to be loaded and run on the
C6713 processor
10.
file.cdb:
configuration file when using DSP/BIOS
1.4 QUICK TEST OF DSK
1.
On power, a program
post.c
(Power On Self Test), stored in onboard flash
memory, uses the board support library (BSL) to test the DSK. It tests the
internal, external, and flash memories, the two multichannel buffered serial
ports (McBSP), direct memory access (DMA), the onboard codec, and the
LEDs. If all tests are successful, all four LEDs blink three times and stop (with
all LEDs on). During the testing of the codec, a 1-kHz tone is generated for
1 sec.
2.
Launch CCS from the icon on the desktop. A USB enumeration process takes
place. Then CCS will be opened and the LEDs will turn off. Press GEL

Quick Test. The Quick Test can be used for confirmation of
correct operation and installation. The following message is then displayed:

This assumes that the four dip switches (0, 1, 2, 3) are all in the up position. Change
the switches to (1110)

so that the first three switches (0, 1, 2) are up and press the
