Hello, I was wondering if you can help me, I have a c5402 DSK and I am trying to run the audio program supplied with the board (c:\ti\c5400\examples\bios\audio ). I have successfully re-written the DSS_init function to setup and enable the AD50 codec and McBSP port. The

Hello all, I'm using the C5402 DSK. When I run the codec program (example), I tried to get the output graph for the time/frequency. Although the output to the speaker is correct, I got weird signal on the graph.( I did't use the probe point since the probe point will kill the

Pegasus Byron- Please check the c54x group archives. Some time ago I posted asm source to the group that shows how to intialize the codec device on the DSK C5402 board directly, without calling CCS functions. That should give you some guidance in working with the A

HI, I am new using interupts. i am using TMS320C6711 dsk board. For communication i am using codec which is connected internally with Mcbsp0. For data transfer and all i want to use EDMA. How to use EDMA and again Mcbsp generates events (like interuptsREVT and XEVT). How

Hi, I am new to DSPs and decided to get started by using the DSK5416. I can't seem to get a single sample from the PCM3002 codec. I can use the plio but want to use the basic PCM3002 methods. e.g. >DSK5416_PCM3002_CodecHandle hCodec; >hCodec = DSK5416_

Hi, I'd like to load a PCM file to the on-board memory and then play it through the PCM3002 codec on the DSK5416. I'm stumped with trying to configure the McBSP for the frequency and bit length of the sample I've loaded. Does anyone have any pointers to how

I have the above audio codec attached to a C54 using a MCBSP to send/receive audio data. We have verified the timing on the CLKX/CLKR, FSX/FSR, and DX/DR signals with an oscope and everything matches the TLV320AIC23 spec. The AIC is programmed as MASTER so it is driving CLKX/CLKR and

Dear Group, I have tried to run the example of DAA operation on C5402 DSK. The board actually goes off-hook, but then the samples from the codec just don't come in. The question is: has anybody encountered such a problem? Could you please give me a clue? I would b

Hi, I encounter a problem with the changing the sampling rate of the onboard codec in C5402 DSK board. I try to set the sampling frequency at 16Khz... but when I test it and found out that it cut off at 4Khz instead of 8Khz.... I try to change to other sampling ra

Hi, I tried using "C intrinsics" provided for ETSI basic ops to help me optimize a speech codec performance. It has a piece of code which reads as for(i = 0; i < 10; i++) a = L_mac(a,b,c); The compiler generates the following code with -03 option

Hi, I am trying to estimate whether I can run a codec code out of extended program space of C5409(100MHz). The extended memory chip is 12ns. And the code needs to finish processing 80 16bit samples within around 1ms. I am not asking people to do calculation for me. Instead, I want t

On a related note to my c5416 current question, I am measuring a current drain of ~78mA from an TLV320AIC23 codec. Nothing is connected to its input or outputs, MIC is powered down. According to the data sheet its typical drain is 23mA when playing back or recording. Brian
