| Abstract: | The Serial peripheral Interface is a sort of technology with high speed and efficiency, which makes the SPI device convenient in data communication. As the interface between kernel of operation system and hardware, the device driver is very important in embedded development. Aiming at the developing platform built on AT91RM9200 and embedded system Linux, the paper analyzes the hardware structure of AT91RM9200 and TLC2543, explains the basic programming method of SPI driver and the realization of dynamic module loading, according to the character of connecting circuit. |
| Keywords: | AT91RM9200 TLC2543 SPI driver Embedded Linux |
