SAI module for TDM communication using eDMA

Hello everybody,

 

I have an application where we need to receive 8 audio channels via TDM format. For this purpose, I am using the SAI module. For improving the performance, I want also to use the eDMA of the device.

 

The problem is that with the SDK I have not been able to receive anything, it always stops after the first transfer.

What I have tried is to follow the example in the SDK's API, but it is using DMA (not eDMA), and I haven't managed to get it working.

 

Does somebody have some working example?

 

I am using a Kinetis K64 device.

 

Thank you in advance,

Ruben
