摘要
SPI接口是一种同步串行通信接口。为了使数据正常进行传输,有时有必要模拟出SPI串口。针对单片机PIC16F884与显示驱动芯片HT1621,提出了软件模拟SPI接口方法,详细阐述了两者之间通信方法的实现过程,提高了系统性能和编程灵活性,减少了误码率。
SPI interface is a synchronous serial communication interface.It s sometimes necessary to simulate SPI for normal datas transmission.In this paper,a SPI interface method with software simulation is mentioned between MCU PIC16F884 and display driver chip HT1621,and between which the implementation process of communication methods is detailed illustrated to improve the system performance and programming flexibility and reduce the error rate.
