Transferring and receiving data with C6711 DSK

Started by K. Raw October 16, 2003
Hi,
    I am not familiar with the TI c6711 DSK and I would like to record and
listen speech data. I can't find any application note that show how to get
started with a simple example.
    Can anybody point me to a pdf or any code sample that might help?
ThanX

Have you installed CCS? If you have, in the Help => Contents, is there a section called "TMS320C6711 DSK"? In that section is there an entry called "Software", with a subentry called "Examples" and a final entry called "Audio"? If so, that provides some information on an Audio example that may be of use. You could also look at: c:\ti\examples\dsk6711\bios\audio (assuming you have installed CCS onto c:\). Best Regards John McCabe To reply by email replace 'nospam' with 'assen'

god... I have worked with C6711DSK for over a year now... I implemented some audio processing using pcm3003 audio daughter card - I also designed and manufactured a daughter card with ADS8364 A2D converter - I wrote software for it... I also had to write assembly code for FIR filtration using circular buffering and "single-instruction-loop"... so - my point is - I have done "a lot" with that DSK - oh - plus - I used DSP/BIOS as well as wrote software bypassing that system... and you know what? I just recently tried to look into that "audio" example - all it does is that it copies input to output - nothing else... but the construction of it is so nasty!!! I don't advice anybody to even look at it! especially beginners! so - if you really want to begin using c6711DSK - start from something "simple" - the audio example is far from simple... also - there is this yahoo group which is very helpful: groups.yahoo.com/group/c6x good luck...

TO be honest, I hadn't looked at that example and you're right, it is a bit overcomplicated for a beginner. However a better idea would be to find a one day workshop to go on if they still run them and work through the lab exercises which includes one on audio. Mainly audio output, but there is a more complicated on on full audio in out with filtering activated via the RTDX interface. EVen if you don't go on the workshop it might be worth trying to get hold of the course materials from someone.

It's also very noisy - I was a member of that for a couple of days and half the questions asked appeared to be basic C questions! Best Regards John McCabe To reply by email replace 'nospam' with 'assen'

well... it's all true - the workshop or any other opportunity to talk to TI specialists can save you weeks or even months of exploring it on your own...

well... it's true - there are a lot of "off-topic" questions and debates, but then - after all - who ask most questions? only newbies and beginners - if you are an experienced engineer - you don't ask questions - you read the manual and you solve the problem... I'm not pretending to be the "experienced engineer", but my activity in that group is probably 95% helping people by answering their questions - well - I just like to read stuff ;-) and the groups is moderated, so it's not really that bad ;-)
Hi,

If you are beginner in C6x programming, you can study/do the labs
given in "DSP system Design: Using the TMS320C6000" by Kehatarnavaz
and Keramat. It also has an Audio Signal Processing example. But, it
requires the use of C6x EVM. Nevertheless, you can get an idea of the
issues involved.

Regards,
Nalin

That'll be "Kehtarnavaz".

Thanks for that reference! Looks interesting. Best Regards John McCabe To reply by email replace 'nospam' with 'assen'
