Clearing the terminal screen?

Question

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 reading

Answer 1

There is no way to clear the screen but, a really easy way to fake it can be printing as much Serial.println(); as you need to keep all the old data out of the screen.

Answer 2

I made this simple function to achieve this:

void clearscreen() { 
    for(int i=0; i<10; i++) {
        Serial.println("\n\n\n\n\n\n\n\n\n\n\n\n\n\n");
    }
}

It works well for me in the default terminal

Answer 3

the best way I can think of is using processing there are a few introductions on the net like displaying serial data, arduino graph and arduino radar
Since Arduino is based on processing its not that hard to learn

Answer 4

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

Answer 5

You could just do:

Serial.println("\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n");

or if you want:

for (int i=0; i<100; i++) {
   Serial.print("\n");
}

/*
As close as I can get to Clear Screen

*/


void setup() {
// put your setup code here, to run once:
Serial.begin(115200);

}

void loop() {

Serial.println("This is Line ZERO ");

// put your main code here, to run repeatedly:

for (int i = 1; i < 37; i++)
{

 // Check and print Line
  if (i == 15)
  {
   Serial.println("Line 15");
  }

  else
   Serial.println(i);  //Prints line numbers   Delete i for blank line
  }

  delay(5000);  

  }
