资料介绍

1 Introduction This application note is a quick start guide on how to use the I2S module as inter-IC sound bus on Kinetis, for the new users. In addition, DMA- and interrupt-based ping-pong buffer scheme is also discussed to reduce the CPU cost for processing the audio data stream. Finally, an example of playing two sine waves of different frequency on each channel is shown for reference. 2 Overview The I2S module on Kinetis has the following five basic operating modes: • Normal mode • Network mode • Gated clock mode • I2S mode • AC97 mode In this application note, only I2S (Inter-IC Sound bus specification) mode is discussed. The I2S timing is shown in Figure 1.
