Arduino Function: TFT.background

Description

Erases everything currently on the LCD screen with the indicated color. Can be used in loop() to clear the screen. While background() expects 8-bit values for each of the red, green, and blue channels, the screen does not display with this fidelity. The red and blue values are scaled to 5-bit color (32 discrete steps), and the green is 6-bit color (64 discrete steps).

Syntax

screen.background(red, green, blue);

Parameters

  • red : int 0-255
  • green : int 0-255
  • blue : int 0-255

Examples

#include <SPI.h>
#include <TFT.h> // Arduino LCD library

#define cs 10
#define dc 9
#define rst 8

TFT screen = TFT(cs, dc, rst);

void setup() {
// initialize the screen
screen.begin();

// make the background white
screen.background(255,255,255);
}

void loop() {}
