In order to meet the demands of wireless data transmission, as well as to resolve the lack of nRF24L01 driver based on Linux, the driver of nRF24L01 is designed based on Linux.nRF24L01 exchanges data with external controller through SPI interface. Firstly,we drive nRF24L01 by using GPIO to simulate the SPI timing to achieve the SPI read and write operation. Secondly, the design of the system is provided, and the hardware interface and software process is disserted and carry on the detailed elaboration to the key functions. Lastly it achieves nRF24L01's wireless transmisson and test to verify the correctness of the driver based on the embedded microprocessor S3C6410.
