Link:https://www.arduino.cc/en/Serial/ReadString Step 4: Serial.readString() Example Code: String a; void setup() { Serial.begin(9600); // opens serial port, sets data rate to 9600 bps } void loop() { while(Serial.available()) { a= Serial.readString();// read the incoming data ...
串口通信(Serial CommunicaTIons)的概念非常简单,串口按位(bit)发送和接收字节。串口用于ASCII码字符的传输,通信使用3根线完成,分别是地线、发送线、接收线.由于串口通信是异步的,端口能够在一根线上发送数据同时在另一根线上接收数据,其他线用于握手,但不是必须的。串口通信最重要的参数是波特率、数据位、停止位和奇偶...

Serial.println(b, DEC) 以十进制形式输出b的ASCII编码值,并同时跟随一个回车和换行符,在测试程序中DEC加与不加效果是完全一样的。 官网对Serial.read()的返回值做出如下介绍:The first byte of incoming serial data available (or -1 if no data is available). Data type: int.,翻译后为:输入的串行数据...

readBytesUntil() 将字符从串行缓冲区读取到一个数组,直到检测到终止字符,或预设的读取长度读取完毕,或者时间到了 setTimeout() 设置使用Serial.readBytesUntil() 或Serial.readBytes()时等待串口数据的最大毫秒值. 默认为1000毫秒 write() 写入二制数据到串口。发送的数据以一个字节或者一系列的字节为单位。如果...
