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 have a question about the McBSPs on the 5402. My problem is this. I have been given the 5402 to use for image processing. I know the sampling rate of 16kHz is too slow however i don't have the liberty of buying a new board with a better sampling rate.

I'm performing speech recognition with the 5402 DSK equipped with AD50 codecs. I need to know how to continuously sample from the microphone port on the DSK. Could someone please provide sample code or help me out with the C functions necessary to perform this continuous sampling usi

Dear friends we know that fs=f(MCLK)/2*TA*TB and fc=136.8k/TA we know also that 4<=TA<=31 2<=TB<=63 TA*TB must be integer,so if we take the minimum and maximum values of TA and TB we get at that time 2.654kHz<= fs<=648kHz from here we see that the

hi all, It is slightly different. I want to detect the 500 and 700 hz fsk signals at 600 baud. I use 8 khz sampling rate and do all the things as a buffered approach. This means I use two 8 k buffers and I process recorded buffer in the mean time recording in

Thank you Motohiko, Emerson, and the other off-line response I got about my microphone sampling question posted previously. I've got a new one for y'alls: Has anyone experienced difficulty running the audio example, not the codec or codec_eg example, including with CCS 1.11? A

Hello all, I'm building an audio processing app, and would like to use DSP/BIOS for the i/o. I'm using CCS 1.2 with the '5402 DSK. Since I'm still new to this platform, I used the audio example in the bios subdirectory as a base for my host program. Trouble is tha

Hi, I posted a message a few weeks ago about this problem but I am still having trouble with a sampling routine being interrupted causing it to miss samples. My setup is: programmed in CCS, using the onboard codec to sample from the mic port, using RTDX to transfe

hi i am receiving a signal of 2MHz and i want to give this signal to a DSP board ..but the problem is that if i dont want to loose the information than i hve to sample it at rate atleast twice the highest frequency ie 4Mhz .. But i the dsp A/D gives only 44.5khz .. Pls

Hi e'bdy, I need some help in selecting a new DSK. We are looking to buy a new DSK/EVM board to support our development work. We look for the following in the new DSK: 1. We would like the DSK to be based on 54x or 55x DSP. 2. It should support common sampling rates l

Hi, I've read past posts on this topic but I can't make the dsplib inverse fft work properly. I put it in a 360Hz sine wave @ 8kHz sampling rate. I get the desired spike in the magnitude spectrum via cbrev(*in, *out, FFTORDER/2); rfft1024(*out, 1); //my little magnituding finding function goes here so I'm sure thats

I am using DSP/BIOS with the RTDX LOG module to transfer debug messages. No stdio / breakpoints are in use. Presently the main functionality of my program is to take 64 samples from the codec and perform an FFT. The problem is that part of the way into the sampling, something

Hello to everyone, I have created a simple project that samples a sinus wave and then it calculates the FFT of the sampling data. I am using a C54x card but what I describe happens in the simulation (I have not tested it in real mode with the card yet.) The program was working but I had forgotten to bit reverse the samples for the FFT. Whether I use the cbrev function (which by the way does...

Hi I work with DSP c5410. Each McBSP is connected to codec AD73360. I am trying to operate them in Simultaneous Sampling. The sampled blocks of data are transferred to an external memory by DMA. Each executes I get a random channels that works properly. I can't manage to operat

Hi friends, I program the c5402 in C language. I see in the codec example that the sampling rates i can configure the codec are only 2kHZ-16kHz using the available function. How can I make the codec to sample at 500 Hz? Is there some other C-callable function which I
