一文搞懂SPI通信协议

SPI 的英文全称为 Serial Peripheral Interface，顾名思义为串行外设接口。SPI 是一种同步串行通信接口规范，主要应用于嵌入式系统中的短距离通信。该接口由摩托罗拉在20世纪80年代中期开发，后发展成了行业规范。 SPI 是一种高速的、全双工的、同步的通信总线 ...

SPI、DSPI、QSPI技术对比

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 ...

Serial Peripheral Interface. SPI, these three letters denote everything you asked for

Electronics is everywhere, especially these days. Many times, as frequent users, we do not even notice a “paradigm change” in the things we use on regular basis. We use a fridge, but we do not care ...
