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
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);
}
