Serial.readBytesUntil()将字符从串行缓冲区读取到一个数组。如果检测到终止字符,或预设的读取长度读取完毕,或者时间到了 (参见 Serial.setTimeout())函数将终止。 Serial.readBytesUntil()返回读入数组的字符数。返回0意味着没有发现有效的数据。 Serial.readBytesUntil()

Arduino的Serial.readBytes()使用例子 找了很久终于在德国一家个人网站上找到的,找了很多,这个比较容易理解,因为不太会用这个语句,写出来以免以后忘记又可以在这里找到啦。真是功夫不负有心人呀,嘻嘻。 源代码注释是德文,我用翻译好用括号括起来了,方便理解。这段代码是通过串口发送字符来PWM LED亮度的代码,似乎...

This example demonstrates string-based communication from the Arduino board to the computer using a call-and-response (handshaking) method. 本例展示了 Arduino 和电脑间的,基于字符串的调用和应答(握手)通信。 The sketch sends an ASCII string on startup and repeats that until it gets a serial respo...
In Processing, select File→Examples→Libraries→Serial→SimpleRead to see an example that reads data from the serial port and changes the color of a rectangle when a switch connected to Arduino is pressed and released. New in Arduino 1.0 Arduino 1.0 introduced a number of Serial enhancements ...
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. ...
