Creating Your First Audio Application from Scratch

This tutorial provides information on how to create an audio project using MPLAB Harmony 3 and the SAM E70 Xplained Ultra board. It starts with a blank MPLAB® project and finishes with an audio application that is a subset of the audio_tone application.

To keep the application as simple as possible, no graphics or other UI are included. It simply outputs a 1000 Hz sine wave over the I2S interface at 48,000 samples/sec. The sine tone is generated internally using math functions (no audio inputs).
