Robot

text()

Description

Write some text to an attached TFT.

When updating the screen, remember to erase the text before writing new text on the same place, or the new/old text will be overlapping each other.

The screen is only 128 pixels tall and 160 pixels wide. It's recommended to use small values for x and y, or text may be cropped/invisible in unpredictable ways.

Syntax

Robot.text(toWrite, x, y, writeOrErase)

Parameters

toWrite: text/value to be written on the LCD. Can be a string, an int or a long.

x: x axis of starting position on the screen.

y: y axis of starting position on the screen.

writeOrErase: specify whether to write the text or erase the text. Use true to write and false to erase.

Returns

none

Examples

#include <ArduinoRobot.h>

void setup(){
  Robot.begin();
  Robot.beginTFT();//Initialize the TFT module
}

void loop(){
  Robot.text("Hello World",0,0,true);
  delay(2000);

  Robot.text("Hello World",0,0,false);//It's necessary to erase the old text, for showing new text
  Robot.text("I am a robot",0,0,true);
  delay(3000);

  Robot.text("I am a robot",0,0,false);
}
