摘　　要：介绍嵌入式Linux系统的驱动原理;分析SPI协议的通信原理和微处理器S3C2440A中SPI接口的硬件结构;阐述SPI驱动程序的实现过程。The driver principle of embedded Linux system was introduced. SPI communication principle and the hardware architecture of the SPI interface in S3C2440A were also analyzed. It focused on the implementation pro- cess of the SPI driver. At last, the testing method had been given to verify the correctness of the SPI driver. The method and principle can be used for reference for research and development of embedded system.
