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 ) ;
