Hi everyone, I am working on DSK5416 and CCS. I'm doing real-time using DMA and McBSP to communicate with the codec. I'm working with 16 bits words and with DSP/BIOS configuration. I would like to know if the problem that I have is coming from data alignment. After interruption (full buffer: 1024 words of 16 bits) I use the following function: Interrupt function(){ int i=0,maxisync,maxica...

Hi all, I tried to use source code available in spra836 document (i2c bus on mcbsp port) on my TMS320c5416 DSK. In this documents I understood that all funtions (init_gpio,i2c_init etc...) are C callable. Someone tried to call these function in a simple C source code ? I tried it, but when I call for example init_gpio, the function seems works good, but at the exit I don't eturn at the correct...

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

I'm trying to set up the bsp for an 8-bit, n-word frame transfer syncronized with the frame sync signal. At the end of the n-word frame I want the interrupt to fire. Ive set up an external pin to toggle inside the interrupt. It continues to fire but randomly and not every frame. Below is my register setup. MCBSP_Config bspConfig = { MCBSP_SPCR1_RMK (

Hi All, I have some query about serial port(McBsp) of C5410. Is it necessary to be clock present always in case of external clock and external frame syncronization signal when serial port is in standard mode. I want to receive data from SPI port by standard serial port. Clock

Hi, my question is possibly a very simple one: Where does the CLKS pin get its clock from? In "Sample Rate Register 2" bit 13 i can choose to derive the sample rate generator clock from CPU clock or from CLKS pin. Where CLKS is an external clock. But where exactly is this external clock from? In "Reference Set Volume
