readBytesUntil() readString() readStringUntil() setTimeout() write() serialEvent() 库函数详解 if (Serial) Description 指示串行口是否准备好 Indicates if the specified Serial port is ready. On 32u4 based boards (Leonardo, Yùn, ecc) , if (Serial) indicates wether or not the USB CDC serial...
The readline() function will read all bytes until a newline character is detected. If we just printed what we received we would see b’Hello from Arduino!\r\n’. You receive bytes when you read from Serial, and you have to convert (decode) those bytes into the appropriate data type. ...
硬件串口通信(UART)——HardwareSerial 类库 除了常见的函数外,另外比较常用的 peek() 功能:返回1字节的数据,但不会从接受缓冲区删除数据,与read()函数不同,read()函数读取该函数后,会从接受缓冲区删除该数据。 write() 功能:输出数据到串口。以字节形式输出到串口,它与print()的区别在于:当使用print()发送一...

“The nature of hardware device interfaces like these is that there is typically no guarantee your data will arrive in a single read(). If you expect 16 bytes of data, you need to read(), successively, until you have received all 16. If you want to read until there is a newline, ...
