Folks I have been dubugging some software on a 6713 DSK using an FFT. I've isolated the problem down to either (a) running the interrupt driven McBSP codec at more than 24kHz sampling rate or (b) running the fast convolution in the main() function using the TI DSPLIB DSPF_sp_cfftr2_dit function with an FFT size greater than 256 points. The stack dump indicates that it's overflowed, and the...


SPI or McBSP for Waveform Generator( TI dsp F2812)

Hi I am using the TI DSP eZdspf2812 DSP as a waveform generator. It is interfaced with a microcontroller. Basically the DSP acts as an encoder, ie it accepts a finite number of bits (1s & 0s) from the microcontroller and generates a waveform corresponding to the bits. Is the GPIO good for this interface between the DSP & microcontroller? Also the waveform goes to a D/A converter. Is it bet...


McBSP as SPI slave

Hi All: I am trying to communicate between C5502 and an Atmel processor with ARM7 core. We want to do the communication using SPI protocol with ARM acting as SPI master and C5502 acting as Slave. In our design, the ARM asserts the slave-enable(SS) signal only once at the start of transmission of the frame and it stays active throughout the transmission of all words in a single frame. The...

hi all can anyone tell me what's the following CSL function have done hMcbsp1 = MCBSP_open(MCBSP_PORT1, MCBSP_OPEN_RESET); if I use folowing code to reset MCBSP1 in C5509a , my program can not generate interrupt. SPCR1_1 = 0x0000; SPCR2_1 = 0x0000; but use MCBSP_open my program interrupt well. all the other code i have not use CSL function.


How to connect AC'97 codec to ADSP-218X?

Hi all: Since AC'97 codec (such as ALC100, ALC210 from realtek) is much cheaper than AD73322 for a stereo project, I'm thinking how to connect AC'97 codec to ADSP-2185 DSP. But the serial ports of ADSP-218x is not so flexible as mcbsp of TI's, it seems very hard for it to connect to AC'97 codec. Is there any references, examples to do this job? Thanks.

Hi all, I'm writing a driver to allow me to communicate from my C6711 to the TLV320AIC23EVM Audio Codec. This communication involves writing the control registers via mcbsp1 and streaming the audio data via mcbsp0. I'm currently trying to write to the control registers on the codec but I'm not sure if I'm doing it right. I have jumped JP1 on my DSP board to connect mcbsp0 to the AIC23 daug...

hi every body, i am using 6713DSK for my project.i use AIC23 for sampling a 1khz sin wave and collect them in a buffer.i configured MCBSP for 32 bit one frame format.after sampling i shift 32 bits samples to right to just have 16 bits of left channel.then when i plot the collected samples in CCS it is not a 1khz sin wave.does anyone know what is my problem. i dont have mush time.please help me if...
