该函数 write() 将数据流通过串口以 二进制数据的形式发出,与 print() 函数是有区别的 语法(Syntax): Serial.write(val) Serial.write(str) Serial.write(buf, len) Arduino Mega 允许使用下列串口: Serial1, Serial2, Serial3 val:单个字节的值 str:一连串字节的字符串 buf:定义的数组 len:指定的数组长度...
print('O'); Serial.print('\n'); // prints a new line character Serial.print('\n'); // prints a new line character // prints a string Serial.print("ArduinoGetStarted.com"); Serial.print("\n\n"); // prints a string with two new line characters // prints a floating point ...
The expressionSerial.print(val,BYTE);is no longer supported in Arduino 1.0. If your code expects byte variables to behave the same as char variables (that is, for them to print as ASCII), you will need to change this toSerial.write(val);. ...
