staticd,
I do not have a dsk6713, so I can only comment on those details I see in the
code.
vectors_intr.asm
I wonder why you have defined all the labels as global, since they are never
referenced by anything.
I see a .global for _c_int11, however, that function/entry point is NOT
defined
within this file, however, because you have defined it as being within this
file, the linker does not pick it up from the RTS6700.lib library.
_c_int11 is a interrupt function in gator_kator.c, so should be .ref
_c_int11.
in file gator_kator.c
the sample rate is defined as 8k samples per second.
That is not near fast enough to recognise a 50khz signal.
You need a sample rate that is more than twice the target frequency, so the
sample rate has to be greater than 100khz.
The code probably will not be able to keep up with the sample rate due to
lack
of input and output buffering and the filter processing being performed
during
the interrupt.
BTW: the code really needs double buffering to have any chance of keeping up
with the samples.
There is, in the 'samples' sub directory of the CCS install, a program
named
"dsp_app" (or something simular) that has a complete application, properly
written for something very similar to what the code is trying to do.
The 'main()' function exits after making 3 function calls.
When the main() function exits, the program exits.
there should be a
"while(1) {;}"
loop before the closing brace of the main() function so the program does not
immediately exit.
These lines:
#include "dsk6713_aic23.h" // codec support
#include "C6713dskinit.h" // function support
are referencing part of the CCS system supplied headers.
I suspect they should be written as:
#include // codec support
#include // function support
The fir_filter.h file seems to be missing from the project.
the error messages:
"../gator_kator.c", line 23: warning #225-D: function declared implicitly
"../gator_kator.c", line 24: warning #225-D: function declared implicitly
indicate either the functions do not exist or the appropriate header file is
not
included.
The warning message:
>> WARNING: invalid version 0, defaulting to 6200
indicates that your project does not have the correct processor selected
or you
need to download/install the *.dll for the 6713 processor.
Again,
Look at the file in the samples directory of the CCS installation for how the
code should be written.
On my computer, running linux, the path to the file(s) of interest is
/home/richard/c6x/demo_app/DSK6416/CCStudio/examples/dsk6416/bsl/disk_app
Your path will be somewhat different depending on your OS and how you
installed
the CCS application.
There is plenty of other details wrong with the application, but this should
be
enough to get you moving in the right direction.
