串行通信和并行通信 在硬件通信里,一般有两种通信方式:串行通信(Serial Communication)和并行通信(Parallel Communication)。这两种通信方式的区别从字面理解也很简单:串行就是数据一个接一个的发送;并行就是所有数据都同时发出。 但由于并行通信在线路成本和同步困难方面的问题使其在实际应用上面远不如串口通信来得广泛。
Serial communication is simply a way to transfer data. The data will be sent sequentially, one bit at a time (1 byte = 8 bits), contrary to parallel communication, where many bits are sent at the same time.UART protocolMore specifically, when you use Serial with Arduino and Raspberry Pi...

A standard Arduino has a single hardware serial port, but serial communication is also possible using software libraries to emulate additional ports (communication channels) to provide connectivity to more than one device. Software serial requires a lot of help from the Arduino controller to send and...
Serial方法是Arduino编程语言中的一个函数,用于与计算机或其他设备进行串行通信。它允许Arduino板与外部设备通过串行通信接口(如USB、UART等)进行数据交换。 Serial方法可以...
在RPI Pico开发板中,内置有USB的IP和物理驱动,这个USB可以配置为串口(CDC,Communication Device Class,USB的一个应用的分类,表示用于通讯的设备,可能是串口,也可能是USB网卡等), HardwareSerial 就没有办法把这类新设备包含进去了。因此,提供了一个新的类 UART 对HardwareSerial 进行了继承封装,兼顾CDC或普通的UART...
This example works only with boards with more than one serial like Arduino Mega, Due, Zero etc. 这个示例仅在有多于一个串口的板子上可以运行,例如:Arduino Mega、Due、Zero 等。 The circuit: 电路连接 - any serial device attached to Serial port 1 ...
At any given time only the master will be able to initiate the communication. Since there is more than one slave in the bus, the master has to refer to each slave using a different address. When addressed only the slave with that particular address will reply back with the information whil...
Arduino has an incredibly simple and convenient serial communication library that enables you to transmit data over serial with only two lines of code! The Arduino serial library will be useful throughout these tutorials as it provides an easy way to display the result of your Arduino’s ...
