Serial.println(data) 从串行端口输出数据,跟随一个回车(ASCII 13, 或‘r’)和一个换行符(ASCII 10, 或‘n’)。这个函数所取得的值与 Serial.print()一样。 Serial.println(b) 以十进制形式输出b的ASCII编码值,并同时跟随一个回车和换行符。 Serial.println(b, DEC) 以十进制形式输出b的ASCII编码值,并同...
arduino的serial.write()和serial.print()的区别在于它们在底层实现和面向对象设计上的运用。从基本层面看，serial.write()用于输出单个字节，而serial.print()则用于输出字符串或整数。这种区别源于面向对象设计中抽象编程与具体编程的层次划分。在arduino的实现中，底层寄存器操作由具体的派生类，如Serial，...

Arduino的串口有两类发送的函数Serial.print()类和Serial.write()类,前者以Ascii码的形式将要发送的内容编码发送,所以我们最后接收并看到的是一个一个的ASCII码组合而成的数据,本质上成了字符串;后者则以字节形式直接发送原始数据,所以我们在串口接收工具看到的数据是乱码,它们在计算机中就是这样存储的。

As a result, your sketch will begin sending data to the USB serial port faster than you can open the serial port. This means that if you have any serial output commands (Serial.print or Serial.println) in your setup() function, you won’t see it in the Serial Monitor because you can...
