摘要
介绍了一种通过SPI接口对编解码器传送控制命令的方法,设计了基于SPI总线的WM8510控制算法,并通过实验验证了算法的有效性。使用SPI接口的编解码器控制方法特别适合于有SPI接口、无I2C接口的系统。
The new method of controlling codec based on SPI bus is introduced. The algorithm of controlling WM8510 based on SPI bus is proposed and experimental results show that the algorithm can be applied to controlling WM8510 successsfully. The method of controlling codec based SPI bus is suitable for the system with SPI interface and without I2C interface.
