摘要
文章介绍了SPI总线接1：7原理，对4种工作模式进行了比较，着重分析了SPI总线的工作时序，然后提出了利用Verilog硬件描述语言实现SPI总线通信协议新方法，最后将该方法在Quartus开发环境下进行了’综合，并在FPGA器件上进行硬件实现、验证。结果证明了该设计正确，并在传输中具有良好的鲁棒性。
This paper on the analysis of the protocol using Verilog introduces the principle of SPI bus interface, SPI bus timing. And then it puts forward a hardware description language ment environment and implemented and verified and has good robustness in transmission. and compares the four work modes, focusing method of achieving SPI bus communication Finally the method is integrated in the in FPGA devices. The results show that the Quartus develop- design is correct and has good robustness in transmission.
