SPI 是英语Serial Peripheral interface的缩写，顾名思义就是串行外围设备接口。是Motorola(摩托罗拉)首先在其MC68HCXX系列处理器上定义的。 SPI，是一种高速的，全双工，同步的通信总线，并且在芯片的管脚上只占用四根线，节约了芯片的管脚，同时为PCB的布局上节省 ...

在嵌入式系统中，串行外设接口（Serial Peripheral Interface，SPI）及其扩展（如 DSPI 和 QSPI）被广泛应用于与外部设备（如传感器、存储器、LCD 控制器等）高速通信。 SPI（Serial Peripheral Interface）是一种全双工同步串行通信协议，通常由主设备（Master）和从设备（Slave ...
