My project for dsk6711 is to build a system that do fft of a signal and
visualize graph of modulo and phase.
The core of application is done, so i have fft modulo and phase of the samples.
Now the visualization: i have some ideas:
- RS232: but how i connect it to DSK6711? There is not a port like in the
DSK5402. I know there are 2 McBsp 0 and 1. The codec use only one, McBsp0 and
the control port, how i connect tx and rx cables of 232 connector? Maybe a
Max232 for converting TTL values but, where I connect Max 232. I know there is
an addon card but I am in an University, the DSK is not mine...
-Audio out: yeah, I could send the spectrum using DAC in codec, how if would be
a sine, simply with mcbsp0_write( sample ) or something like it, in the same
Interroupt Service Routine in which i read sample and compute fft? fft is when
the array of 1024/2048/4096 samples is complete, if not i put sample with
sample=mcbsp_read() in the array, and i have thouht that during this part i can
write out my data. I've tryed this way but dsp don't run. Maybe I have
made mistake, but the code without write work well, maybe I can't read and
write from codec in the same ISR? But i have seen in many examples that is
possible, codec is full-duplex!
-LPT : the problem is that code composer use the lpt. My dreams is to eliminate
code composer, dsk can run program stored in flash? I have seen i have to use
RTDX or HSRTDX, could you say me a complete example eviroment ( host prgram and
target code to run for it) to learn how to use this? THere is not and index in
the dsk examples i feel vwry imbarassd!
I wish somebody help me replyng me. Bye!

Did you see my previous e-mail? I sent you a link of software that can talk to the DSK 6711 directly without CCS.

I haven't looked at the DirectDSP - DSK C6711 Reference Guide in a long time, so I took a look today and I agree there
should be a section in there "how to use with your DSP application". Here are some brief notes:
1) c6x11hi.out - this is the DirectDSP "talker" program. You need that one. The talker is the "DSP side" of the
board driver (other side being WinNT/WinXP driver). On C6x devices, the HPI cannot see all internal memory and/or
mem-mapped register locations, so the talker is used to give the host complete visibility.
2) tmsc6x11.out - this is a sample application DSP program. Example only.
3) You can change the Dscope32MFC.cpp file (and other .cpp files if needed) as needed, using Microsoft Visual Studio.
You can download and run your .out file (instead of tmsc6x11.out), you can change the user-interface, you can access
DSP memory as needed, etc. Look for an API "DSLoadFileProcessor" to see where application DSP code is being
downdloaded.
4) When you create your DSP application, you want modify your CCS project .cmd file to reserve a section in DSP memory
for the talker; i.e. you don't want your code, when it is downloaded, to step on the talker (which is already residing
in DSP mem, having been loaded when the driver was first opened by WinXP). On Monday, I will upload example .cmd
files to the ftp://ftp.signalogic.com/software/DirectDSP_DSK/ page, one for the talker and one for an example
application. Then you can see:
-what mem the talker uses (a small amount)
-how to reserve-out talker mem when CCS builds
your application

Hi jeff! I have reply you in the other thread where you have very gently sent me
the link, but yahoo group did not send my reply yet, It seems that every mail
must be validated by someone, and i thind that one or two of my reply did not
validated but I don't know why, I haven't say nothing of bad, or
incorrect. Misterys of the life...I wish this message arrives in time!!! So, i
have written that I don't understand how to implement that program beacuse,
for what i have understand, that program wants to load another .out in the
target.I have seen in the ftp archive that there is a source code of the host
program but sincerely i have not read a line yet. I have visited the company
site of that program, and i have understand that it's an host software
about specturm/ in time analisys of the audio signal [ that is essentially what
i have to do but creating my own code ]. But is a black box , thats works but
closed, for the target app. Could you give me some
information about that software and how can i implement it? I tell you my objectives: I'd like to caputre audio signal, do fft and vview a Bode grapfh, on the pc host. The part involving fft is done only the visualization is bringing me crazy.
Excuse me if I don't understand immediatly what you have maybe yet say to me :(
Have a good day!
