Upload above sketch, enter some data and look at the serial monitor to see what Arduino received. Fig. 1 shows the data received by Arduino in (Decimal)(Hex)(Character) format. You can repeat the same by changing the modes of the serial monitor. Set the serial monitor to ‘no line end...

Serial.print(tab[key/16],BYTE); Serial.print(tab[key%16],BYTE); } press = 0; key = 0; } 把程序编译后烧进Arduino,然后把按下Arduino编程软件的Serial Monitor按钮,在代码窗口下面就会显示出串口监视器的串口,在下拉列表中把波特率改为9600即我们设置的通信波特率。然后按下键盘上的按钮,就能在窗口中...
双击Arduino IDE工具栏的“Serial Monitor”工具图标,会打开串口监视器窗口。如果运行图3所示任务的程序,在窗口中,会看到电位计的电压值实时变化,你在“Send”输入栏里,输入‘a’字符,Proteus仿真图的LED灯会点亮,输入‘b’字符,LED会熄灭。这说明COM7和COM8这两个虚拟串口能正确仿真串行通讯,就好像两个物理串口在...

You can also send data from the Serial Monitor to Arduino by entering text in the text box to the left of the Send button. Baud rate (the speed at which data is transmitted, measured in bits per second) is selected using the drop-down box on the bottom right. You can use the drop...
Serial Monitor 接收不到, 一定要拔走 D0/D1 的連線, 才可以發送到 Serial Monitor, 所以我不肯定...
