| Abstract: | UDA1341 supports the IIS bus data format, which is able to operate under three work modes. normal transfers, DMA, and transmission/receipt. The paper discusses the driver of UDA1341 on ARMLinux with a focus on the design of the buffering device as well as the playing and recording of audio data. The development of the driver is thereby completed through the realization of its functions. |
