I still haven't resolved my problem with the AIC23 on the TMS320C6455EVM. After viewing the different options available, I tried to use the Data Converter Support by selecting "Codec, Serial interface -> 18-24 bit -> TLV320AIC23: 96kHz, Audio, Stereo -> Aic23_4" and then setting the AIC23 mode to USB and selecting 48/48 kHz sampling rates and insured that the Line Input is activated. In the DSP

HI EVEYONE.I am trying to implement iir filter on c6713.MY Signal has a bandwidth of 150hz.The minimum sampling rate of c6713 is 8khz.I need to sample at 1khz.This means i have to downsample it. My code is interrupt based.What i want to ask is whether i will downsample before or after filtering.Any sample code regarding downsampling would be of great help. Any response in this regard would be o...

Hi everybody, I have a simple question. I am using the DSK6711 which has an AD535 on board. The AD535 has the sampling frequency limited to 8 Khz. Does this also mean that i will be unable to play out audio through the ad535 at a higher frequency, or is it just that the input analog signal will be sampled only at 8 Khz? Thanks and regards -Sunil

Hi all I want to receive 70 MHz PM+BPSK modulated signal. Video bandwidth:138 kHz Modulation index for PM: 1.2 radian Subcarrier frequency of BPSK:65536 Hz. I have been using Matlab /Simulink and TMS320C6713 DSK. 1. I need suitable ADC daughtercard for C6713 DSK. 2. What is the sampling rate according to this spec.s? How can I calculate? I want to proof my calculation method. ...

I have seen many examples of connecting an ADC to the McBSP port where the sampling rate is controlled by a clock generated by the DSP chip. I have an application where the clock will come from an encoder connected to the shaft of a motor. I am trying to figure out if there is an efficient way to do this with the DSP architecture. I don't think it can be done using the McBSP. The s...

Hello, Im planning a 6713DSK based design and am thinking of using timer1 to create a periodic ISR to handle continuous sampling an of ADC.(Im still very new with this DSK, and so havent tried it out myself) Assuming I keep the ISR short (ie: read the ADC, toggle a GPIO, output to a DAC, some housekeeping), can someone give me a rough estimate of how fast I can expect to be able to sample ? ...

Dear All I am using c6713 dsk with CCS software. it's sampling frequency minimum 8KHz , max 99KHz & 256 FFT point. I want to process real signal 0.5Hz to 10 Hz. Is it possible to process or do FFT for this frequency band ? If not, how can i do it ... Your kind help will be highly appreciated.

I have a few questions about C6713 DSK. Is it possible to integrate a daughtercard including ADC working around 300 ksps to C6713. If yes, would you like to suggest this type of products? I am using Matlab/Simulink to obtain CCS projects. Is there any products having simulink adc/dac blocks. I want to design FM demodulator+BPSK demodulator. My IF frequency is 70 Mhz, video bandwith 138kHz...

Howdy, I'm using the audio daughter card on the 6713 DSK, which is sampling stereo 48 kHz. I believe this rate is fixed, via the jumpers on the board. I want to sample the data, but then decimate it to a lower rate, and send it back out to the daughter card. Howe

I have not used dm642 before. But want to know about its video ports. Few Q's are below. Can someone help me in them... Can it be used for video signal i\p as well o\p? i think it is for dual purpose! What is signal i\p and o\p format(RGB\YCbCr sampling rate etc)? Can we set desired frame size and frame rate?
