SPI、UART、I2C通信的区别与应用

电子设备之间的通信就像人类之间的交流，双方都需要说相同的语言。在电子产品中，这些语言称为通信协议。之前有单独地分享了SPI、UART、I2C通信的文章，这篇对它们做一些对比。串行 VS 并行电子设备通过发送数据位从而实现相互交谈。位是二进制的 ...

浅谈 SPI、I2C、UART、I2S、GPIO、SDIO、CAN

总线，总线，总要陷进里面。这世界上的信号都一样，但是总线却成千上万，让人‍头疼。总的来说，总线有三种：内部总线、系统总线和外部总线。内部总线是微机内部各外围芯片与处理器之间的总线，用于芯片一级的互连；系统总线是微机中各插件板与 ...

为什么选择UART（串口）作为调试接口，而不是I2C、SPI等其他接口

协议简单：UART的协议非常简单，只需设置波特率、数据位、停止位和校验位就可以进行通信。相比之下，I2C和SPI需要处理更多的通信协议和时序要求。硬件资源少：UART通信通常只需要两根线（TX和RX），而I2C需要两根线（SCL和SDA），SPI需要至少四根线（MISO、MOSI ...
