Serial.read(); 参数 None 返回 返回串口缓存中第一个可读字节,当没有可读数据时返回-1,整数类型。 示例 charcomchar; voidsetup() { Serial.begin(9600); while(Serial.read()>= 0){}/ /clear serialbuffer } voidloop() { // read data from serial port while(Serial.available()>0){ comchar =...
while (Serial.available()) { // get the new byte: char inChar = (char)Serial.read(); // add it to the inputString: inputString += inChar; // if the incoming character is a newline, set a flag // so the main loop can do something about it: if (inChar == '\n') { stri...
intred=Serial.parseInt();intgreen=Serial.parseInt();intblue=Serial.parseInt(); Once you've read the data into your variables, check for the newline character to proceed: 一旦将数据读取到变量,检查一个换行符来继续: if(Serial.read()=='\n'){ Usingconstrain(), you can keep the values in ...
1 在连接硬件之前，大家仔细看这块开发板的硬件连接说明。硬件连接，装备好一个ARDUINO板一个，USB线一根，这里USB线充当电源线，因为ARDUINO板电压为3.V-12V都可以用。准备好后按图连接。2 基本连接如下图所示。安全起见，加上二个电阻如果仅是低电压的测试也可以按图二连接测试具体的接法，一定要注意开发板收发...

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...
