Hi, I want to implement a random number generator into my C5410 DSP. I have found code for rand routines, but I have noticed the seed of the generator is always the same, so the numbers generated are each time I begin my program the same. Is there any way to achieve a "real" random initialization, so not always the same numbers being generated? Thanks

Hello All- I need some help on figuring out how to disable the DAA on the c54cst chip. I figure it has something to do with initialization driver but I am still confused if whether or not I need to disable it hardware-wise as well.

Hi all, I am using a DMA channel with autoinitialization. I have a frame of 4 16-bit words. My question is how I have to configure the DMA and the McBSP in order to synchronize the DMA to the frame sync signal. The problem is that the McBSP gives an event every 16-bit wo
