i.MX RT series data conversion from SPDIF to I2S

Hello,

 

I have the codes for receiving SPDIF input and I2S output on i.MX RT processors, but I'm trying to find if there's any standard or most optimized way of converting the data for i.MX RT processors. Could anyone share if there's any documents or code examples which does the conversion?

 

Best regards

Brian

There is no any internal hardware interconnection between SPDIF and SAI modules
inside i.MX RT SoCs. So, the only way to transfer audio from SPDIF to SAI is to
receive data from SPDIF, buffer them into memory and then send them to SAI
under software control, possibly, using DMA.

Best Regards,

Artur
