Analog I/O Example For The NXP LPC55S69-EVK

 I recently wrote some DSP code for the excellent NXP LPC55S69-EVK.

The standard audio I/O example for the LPC55S69-EVK implements a very simple piece of code to read in an array of audio data from the stereo codec and then write it back. It does not show how to access that data or process it using background DSP functions.

I have written an example that uses interrupts, ping-pong buffers and background tasks to apply DSP functions to the real-time audio datastream.

The example can be downloaded from:
