嵌入式 - Bit banging介绍

位操作是计算机和电子技术中使用软件而非专用硬件进行串行通信的一种技术。在位操作中，微控制器或处理器通过在软件中切换通用输入/输出（GPIO）引脚的状态来生成和读取这些引脚上的串行数据。这使得通信协议可以完全在软件中实现，而无需专门的通信硬件模块。

Bit banging is a technique used in computing and electronics to perform serial communication using software instead of dedicated hardware. In bit banging, the microcontroller or processor generates and reads the serial data on general-purpose input/output (GPIO) pins by toggling the state of the pins in software. This allows for communication protocols to be implemented purely in software without the need for specialized communication hardware modules.
