SPI Interface and Its Application in Data Exchange
LI Xiao-wen · Communications technology · 2007
SPI is a common-use serial communication protocol,which is used for communication between MCU and peripherals.Taking the SPI interface of OMAP1612 as an example,the paper gives an account of the structure,including the port for SPI interface and register etc,and describes the SPI protocol in detail.The SPI receive/transmit process of MCU-DSP receive/transmit protocol in master mode is also given,including the simulation of the whole process with FPGA in the terminal.
