To use the display with an Arduino UNO, you will need to install the appropriate library, such as the Adafruit_GFX library and a driver library for the ILI9486/ILI9488 controller.
#include <Adafruit_GFX.h> // Core graphics library
#include <MCUFRIEND_kbv.h> // Hardware-specific library
MCUFRIEND_kbv tft; // Instantiate a display object
void setup() {
uint16_t ID = tft.readID(); // Read display driver ID
tft.begin(ID); // Initialize the display
tft.setRotation(1); // Set display rotation
tft.fillScreen(TFT_BLACK); // Clear the screen
}
void loop() {
// Your code to draw on the display
}
Q: Can I use this display with a 5V system? A: Yes, the display is 5V tolerant, but it is recommended to use a level shifter for logic level conversion.
Q: How do I adjust the brightness of the backlight? A: The backlight brightness can be controlled by applying a PWM signal to the LED pin.
Q: What libraries do I need for the touch functionality? A: You will need a touch screen library compatible with your display's touch controller, such as the URTouch library for Arduino.
