| Abstract: | This paper applied S3C2440 microprocessor and embedded Linux operating system as a development platform, designed an SPI driver based on SPI communication principle and SPI interface in S3C2440. And the paper mainly described the basic development method and implementation process. The correction of SPI driver was verified by writing simple testing codes. It is proved that the driver is stable and reliable,enabling communication in embedded system. |
