Abstract: This paper presents the application of SPI to the interface between the wireless RF
processor and the ARM microprocessor (AT91RM9200), and describes the connection of the
CC2420 and AT91RM9200 as well as its driver. The connection method is also applicable to the other wireless RF processor and microprocessor that have the functions of SPI. The serial
communication between CC2420 and AT91RM9200 based on the SPI also provides a solution
for the hardware node of wireless sensor network.
Key words: embedded Linux; SPI; driver; AT91RM9200; CC2420
