C5535 eZdsp // I2s2 + Dma1 problem

Hi TI,

I'm trying to do an applications on the eZdsp c5535 that gets audio from a guitar , manipulates it and throws it. I'm planning to do it with the help of DMA. My idea was that the audio codec will get 8x 16 bits guitar audio frames from I2S, then DMA moves to cpu, manipulation, then back to the codec with DMA 8x 16 data frames again and throw throgu I2S.

I've red a lot of examples, including csl examples, ezdsp examples... but I can't find the proper way to do that. So my question is wich would be the best way to do a project like this. I'll apreciate some examples of configuring both I2S and DMA.
