Implementation of SPI and driver for CC2430 and C8051F120

The SPI bus is a sort of synchronized serial peripheral interface, it causes microcontroller unit (MCU) to carry on the communication with each kind of peripheral by the serial mode to exchange the information. The paper introduces the procedure of delivering the information from the CC2430 with wireless transceiver function interface to the C8051F120 by serial peripherals interface. The work also shows the connection request of hardware and the method of the realization for the driver. It provides a solution for the communication of CC2430 and C8051F120.
