在给Arduino编程的时候,因为没有调试工具,经常要通过使用串口通讯的方式调用Serial.print和Serial.println输出Arduino运行过程中的相关信息,然后在电脑上用Arduino IDE的Serial Monitor来查看print出来的信息。Serial Monitor不仅可以接受Arduino发送到电脑的数据,还可以向Arduino发送数据,进行双向通讯。但是这种通讯方式太过于简...

例如我们做一个模拟电压采集，采集到的数值，只需要用Serial.print()发送出来，彩屏就会把电压值显示出来。下面我们分享一个案例：我们使用最常见的UNO主板，接上ATF串口智能屏。（用到VCC-GND-TX-RX四条线）使用Arduinio IDE自带的ASCII Table例程。将例程上传到UNO主板中。然后打开串口监视器（Serial.monitor），...

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...
