I'm looking for a good driver example for the Codec hardware that is missing from the FRDM-K22F default factory board that is currently shipping. The SDK seems to have sai.c/sai.h files, but it would be nice if I had a complete audio I/O code project for the K22F. I'm sure one must exist somewhere at NXP since you have the hardware design, right?
Also, is there a different part number version of the K22F that has all the audio components stuffed for the Codec and connectors?
If not, then I'm trying to work through the details of which ports are used and if there is pin support to the shield connectors to design a different Codec shield board.
I see this FRDM-K22F_manifest.xml file which seems to organize the files needed for each project example in "Projects of Projects" imports. Is this a tool generated file or needs to be manually edited to add necessary files to complete the driver project lists (to add I2S capability)?
