Now that we have a firm understanding of how we need to configure the signals to communicate with a SPI component, let’s look at the Arduino SPI Library that will actually manage all of that signaling for us. Objectives Determine which commands are used to configure the SPI interactions Lear...

MOSI–SPI总线主机输出/ 从机输入(SPI Bus Master Output/Slave Input); MISO–SPI总线主机输入/ 从机输出(SPI Bus Master Input/Slave Output); SCLK–时钟信号,由主设备产生; CS–从设备使能信号,由主设备控制(Chip select),有的IC此pin脚叫SS。
shiftOut(dataPin, clockPin, bitOrder, value) SPI外部IO扩展函数,通常使用带SPI接口的74HC595做8个IO扩展,dataPin为数据口,clockPin为时钟口,bitOrder为数据传输方向(MSBFIRST高位在前,LSBFIRST低位在前),value表示所要传送的数据(0～255),另外还需要一个IO口做74HC595的使能控制。
