I'm developing a USB audio interface with a FRDM-K66F board and KSDK 2.x. Just reading the documentation here: http://cache.freescale.com/files/training/Enhanced-Direct-Memory-Access-Controller-Training.pdf
It includes an example for an "Audio equalizer". Is there any source code with this example? It'd be extremely useful to me in development.
Alternatively, are there any examples which show how to set up the DMA controller for USB to SAI peripheral using ping-pong buffers?
Many thanks, Don
