SCL是时钟引脚,SDA是数据引脚。 SPI通信需要3个引脚或者4个引脚:CS SCK MOSI MISO。SPI通信芯片的引脚名称不一定都是这几个名称,可能还有会别的名称,但是意思是一样的,例如MOSI引脚的意思是“主机输出从机输入”,某个SPI接口的芯片就有可能会写成SDI,因为这个SPI器件是作为从机的,所以它的SDI的意思就是“从机...
I2C通信中使用两个信号线SDA、SCL，分别为数据线和时钟线。SPI通信中使用4根信号线MISI、MISO、SCLK、SS，分别为数据输入、数据输出、时钟和使能端，NC表示空脚。
TEST-EN: 检测使能；MOSI：多出单入；SDA：串行数据（总线）；MISO：多入单出；你是？
