清除终端屏幕? [英] Clearing the terminal screen?

问题描述

我正在从机器人的9个不同传感器中读取数据，我需要在同一窗口中稳定地显示所有数据，以便我可以比较这些值并查看是否有任何读数不正确.

I'm reading data from 9 different sensors for my robot and I need to display them all steadily, in the same window so I can compare the values and see if any of the readings is off.

Serial.print和lcd.print的问题在于值一直在移动，并且在移动机器人时我无法真正看清它们.

The problem I'm having with both Serial.print and lcd.print is that the values are constantly moving and I can't really have a good look at them while moving the robot.

我本来想在显示其他任何内容之前先调用Serial.clear()之类的东西，那样只会使事情稳定并在一处，仅更改值.

I was thinking to call something like Serial.clear() before displaying anything else and that would just keep things steady and in one place, changing only the values.

到目前为止，我发现不再支持Serial.print(17，BYTE)(调用ESC键).

From what I found so far, Serial.print(17,BYTE) for instance is no longer supported (Calling the ESC key).

那么...对于那些有更多Arduino经验的人...什么是正确的方法呢?

So...for those with a bit more Arduino experience...what is the proper way to do this?

推荐答案

Arduino串行监视器不是常规终端，因此无法使用标准终端命令清除屏幕.我建议使用实际的终端模拟器，例如腻子.

The Arduino serial monitor isn't a regular terminal so its not possible to clear the screen using standard terminal commands. I suggest using an actual terminal emulator, like Putty.

清除终端屏幕的命令是ESC [2J

The command for clearing a terminal screen is ESC[2J

要在Arduino代码中完成:

To accomplish in Arduino code:

  Serial.write(27);       // ESC command
  Serial.print("[2J");    // clear screen command
  Serial.write(27);
  Serial.print("[H");     // cursor to home command
