摘要
讨论了在WinCE5.0操作系统下,基于AT91SAM9260 ARM平台,控制WM8731音频芯片的音频驱动设计,在驱动设计中利用AT91SAM9260的SPI和SSC实现对WM8731的控制和音频数据传输,并在驱动中设立多缓冲有效地提高了语音数据的实时处理,设计的驱动器可以支持同时录放音,并在实际应用中取得了很好的效果.
This paper describes the design of the audio driver WM8731 under the WinCE5.0 operating system and based on AT91SAM9260.The SPI and SSC of AT91SAM9260 are used to control WM8731 and transport audio data flow.More buffers are built to improve the real-time processing of audio data effectively.The driver can support recording and playing audio data at the same time and performs well in real applications.
