Hi, I am programming the codec AD50 onboard the C5402DSKplus now. I could write to the codec registers correctly by a series of primary and secondary communications. With diffrent control words, I could change the gains and the sampling rate. However, once t

Hi all, I'm developing with TMS320C5416 DSP and TLV320AIC12 codec. 16 bits samples at 8000 Hz sampling frecuency, are received into a buffer. When this buffer is full,I code it through G.729 ITU codec and then I decode it. But, when I write the decoded buff

hie i'm developing a spectrum analyser on a tms320c5x using the fft algorithim.now i'm trying to analyse a frequecy range of around 4khz thats about 8khz of sampling rate for speech. i want to get data from say a microphone (the chip has an RCA jack for "mikes")into memory space for processing by the fft codewhich i made (digital stage) and t

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 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 am using the AIC10 EVM piggy pack on a C5402 DSK for an audio project. I get a tone on the speaker (DAC output) at the sampling frequency, i.e. if I sample at 8 kHz, I hear an annoying 8 kHz tone on the speakers, or if I sample at 5 kHz, I get a 5 kHz tone. Can anyone hel

Hi All, I am trying to set up an ADC to interface with my DSP and I was wondering-- what is keeping me from "underclocking" the ADC? It's specified sampling rate is 65 MSPS, but I clock it at 50 MSPS, so I can clock it with the DSP unit, rather than setting up a cloc

Dear all I have a problem with DSPlib for tms320VC5416 chip. I use POWER function from dsplib library to calculate the sum of sqrs of an input array. It was ok until I add ST-BUS support to the project. I get input data from ulaw codecs with sampling rate of 8000 sample per second. Because ST-BUS consists of 32 channels, it interrupts my chip 256000 times in a second. But adding ST-BU...

Hi   I am using TIs DM 270 EVM for an audio application.i.e for audio recording.   and I am facing some problem while sampling audio .unknown value is sampled if no input is there and it is coming as mechine like sound (small amount in the left head phone).   Does any one know how to configure the ADC and McBSP
