hi, I'm trying to interface audio codec and SDcard with DSP[DM642]... SDcard is connected with MCBSP port and audio codec is connected with MCASP0.... I'm also using Video port 1 and video port 2.. In the datasheet, it is given that MCASP0's control is in videoport 0 and data is in videoport 1... My doubt is i'm using videoport 1 for video in interfacing... If i connect the MCASP...

Hi I am using the ezdsp F2812. I am thinking of purchasing Matlab's embedded target for TIC2000. My application involves using the GPIOs, SPI, McBSP, ADC as well as implementing FFT, filtering & other DSP algorithms. How helpful is this for code generation? Is it really worth buying it? I am sure someone on this group must have used it. Thanks. Vikram

Hi again everyone, I'm currently writing a driver to interface between the McBsps on my c6711DSK and the AIC23EVM Codec. Currently I am at the stage where I can do all the Control (via mcbsp1) and I can also read from the ADCs on the Codec via McBSP0. My problem though is that I cant write to the DACs, despite the fact that the the timing diagram for reading and writing to the codec via Mc...

Hi, I work with a TI DSP (C6713). I read and write data with MCBSP and EDMA (Ping Pong buffering). Now my question is how long will it take to send one Sample from the Input to the Output. The Samplefreq is 48KHz and the Buffersize 128Samples. I am not sure if the right answer is 128/48000=2.66ms or 2*128/48000=5.33ms. Thanks

Hello ! I have a big problem with the dsk TMS320C6711. I must implement a MIMO (multi antenna) system, and I don't know if it's possible to transmit data in parallel. I should send Inphase and Quadrature part of a signal to 2 antennas. I have also 4 channels. (for example 4 frames of 128 bits) I think that I must use EDMA or McBSP but I don't know very well DSPs. I hope that someone can ...

Little circuitry allows addressing, i.e. its possible to select single slave for SPI master-to-slave...
