读取到的字符串存储在inputString变量中,并通过Serial.println(inputString);打印出来。 请注意,Serial.readStringUntil(' ')会读取直到遇到指定的终止字符(在这个例子中是换行符 )为止的所有字符。如果你希望读取固定长度的字符串,可以使用Serial.readBytes()函数。 此外,在实际应用中,你可能还需要考虑串口通信的波特率...
而且一般都是使用官方的Arduino IDE来写程序控制Arduino硬件。
Serial.readStringUntil(terminator) 参数 terminator:终止字符(cha型) 返回 从串口缓存区中读取的整个字符串,直至检测到终止字符。 示例 String comdata = ""; char terminator = ','; void setup() { Serial.begin(9600); while(Serial.read()>= 0){} //clear serialbuffer } void loop() { // read ...

如果是Arduino Leonardo:if(Seriall) 如果是Arduino Mega:if (Serial1) ,if (Serial2) ,if (Serial3) 参数:无 返回值: 布尔值(boolean):如果指定的串行端口可用,则返回true。 只有在查询Leonardo的USB CDC串行连接准备就绪之前,此操作才会返回false。
Also, we add a newline character ‘\n’ because that’s what the Arduino is expected to end its reading with Serial.readStringUntil(‘\n’). Then, we do the same thing as we did before: we read a line, decode it to string, and remove any trailing character. We’re not using the...
You can use the following statement to discard all data in the receive buffer: while(Serial.read() >= 0) ; // flush the receive buffer. Serial.write and Serial.print do not block. Older versions of Arduino would wait until all characters were sent before returning. Instead, characters ...
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...
Thereadlinesmethod is part of theSerialclass in theserialmodule. It reads data from the serial port until a newline character (\n) is encountered. The method returns a list of strings, where each string is a line of data read from the serial port. ...
