If I generate the McBSP frame sync, and clock internally, can I simulate the McBSP? I have set up DMA to service the McBSP, but aside from feeding DXR one or two words, it just sits there without advancing. I do not see the status bits of the SPCR changing, so my guess is that

Can i use McBSP for interfacing of stereo signal (left and right channels) i.e. I2S. if yes, then how? I want to connect to ADC with McBSP. how can i pick up signal from two McBSP. As clock to both ADC is same. I want to get signal from both ADCs with different input signals. How can i get data from two McBSP without losing data from any McBSP. if i choose interrupt, will i get data from two Mc...

Hi All, I am using the DSK6455 which includes two MCBSP port and these two MCBSP port of 6455 can be use as a SPI interface. In my system I use both MCBSP port to interface with ADC/DAC so there is no free MCBSP port. As I need another port to interface with a MCU which require a data rate at about 30Mb/s, so I decided to use the SPI interface. Since there is no free MCBSP port in my sys...
