Serial.point(1.23456,3); 得到“1.234” Serial.print("Hello World!"); 得到“Hello World!” Serial.println() 串口输出数据函数,与Serial.print()不同的是输出数据带回车符 Serial.write() 串口输出数据函数,写二进制数据到串口 Serial.write(buf,len); 返回值是字节 Serial.serialEvent() 串口数据准备好...

But USB is hard, and you just want to transfer your every-day serial data from a microcontroller to computer. What now? Enter the FTDI Friend! The FTDI Friend is a tweaked out FTDI FT232RL chip adapter. Sure, like the well-known FTDI cable, it can provide power to your project... ...

Serial.print("The number is "); prints this: The number is The values (numbers) that you print depend on the type of variable; seeRecipe 4.2for more about this. But for now, printing an integer will print its numeric value, so if the variablenumberis1, the following code: ...
In this Arduino Serial example, we will write text to the Arduino serial port, which will send it over the USB cable to your computer, which will then display that text in a terminal window. In the ‘setup()’ function mentioned above, add the following lines to start the Arduino serial...
Serial.print ("/"); } encoder0PinALast = n; } 要注意的几点: encoder0Pos会一直记数,那也就意味着假设电机一直向一个方向进行旋转。那么串口消息会变的非常长(最多6个字符),这种话就会画很多其它的时间去转换。你须要保证当encoder0Pos溢出的时候。在你的PC端不会发生bugs-假设它的值大于INT的最大值(...
Serial.println(text);does the same as print, but will add a new line after the message. '\n' is a newline character, '\r' is a carriage return, and '\t' is the tab character (for indentations) Serial.write(byte);sends a raw byte over serial. For example, Serial.write(48); ...
