Clearing the terminal screen?

arduino, erase, refresh, terminal

Solution

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.

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

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

Problem

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. 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. 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. From what I found so far, Serial.print(17,BYTE) for instance is no longer supported (Calling the ESC key). So...for those with a bit more Arduino experience...what is the proper way to do this?
