【Abstract】 This paper introduces a design of nRF24L01 RF module driver by using SPI controller based on the S3C2440 ARM processor and embedded Linux operating system. We discuss the nRF24L01 RF module hardware circuit, and design the RF module driver by referring to the course of the char device driver development. In the end, we realize the communication between the nRF24L01 RF modules. The RF module has a wide range of applications in the field of 2.45G wireless communication.更多还原
