I2S with DMA using a C5535

ramesh snell
Prodigy 120 points

Hello 

I am using a C5535 (on the eZdsp) and want to use the I2S under DMA control to continuously write 512 samples of 32bit data ie 2048 Bytes to memory.

So typically, I would use two buffers to swap/alternate between so there is no lost of data. Is this possible with this chip is so, do you have code that demonstrate this requirement?

Thanks,

Ramesh

    Hi,

    Yes , it supports. But further suggest you  to look at the C5535 datasheet to confirm on all your requirements.

    There exists I2S with DMA related example in CSL package. You can try refering to "CSL_I2S_AudioCodec_DMA"  CSL example in C55XCSL-C5517-AUXPACK  - available in sprc133 .

    Hope this helps.

    Regards
