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

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


DSPLIB and ST-BUS interrupts problem

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...
