SPI（Serial Peripheral interface, 串行外设接口）是微处理控制单元(MCU)和外围IC（如传感器、ADC、DAC、驱动芯片和外部存储设备等）之间进行通信的同步串行端口，其通信速率一般可以从几千bps到几百Mbps甚至更高, 具体的SPI通信速率取决于主设备和从设备的规格和性能 ...

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首先在其MC68HCXX系列处理器上定义的。SPI接口主要应用在 EEPROM，FLASH，实时时钟，AD转换器，还有数字信号处理器和数字信号解码器之间。SPI，是一种高速的，全双工，同步的通信 ...

SPI在嵌入式系统中非常普遍。无论是芯片上的系统处理器（如ARM、MIC或Power PC等高端32位处理器）还是微控制器（如AVR、PIC等），通常包括能够以主从模式运行的SPI控制器。系统内可编程AVR控制器可以使用SPI接口编程；基于芯片或FPGA的设计有时使用SPI进行通信。
