Usage Instructions

Connecting to an Arduino UNO

Connect the display module to the Arduino UNO using jumper wires according to the pin configuration.
Ensure that the power supply to the display is stable and within the specified voltage range.
If the display has a touch feature, connect the touch pins accordingly.

Programming the Display

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
}

Best Practices

Always handle the display with care to avoid physical damage.
Avoid exposing the display to extreme temperatures or moisture.
Use a level shifter if you are interfacing with a 5V microcontroller to ensure the logic levels are compatible.

Troubleshooting and FAQs

Common Issues

Display not powering on: Check the power supply and connections.
White screen: Ensure the correct driver library is installed and initialized with the right display driver ID.
Touch not responsive: Verify the touch pin connections and calibrate the touch screen if necessary.

FAQs

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.
