How to Display Image in TFT Display with SD card Module

A Step-by-Step Guide to Displaying Images on a TFT Display using an SD Card Module with Arduino

Introduction:

In the world of electronics, displaying images on TFT (Thin Film Transistor) displays is an exciting way to enhance visual projects. By leveraging an SD card module and an Arduino, you can create stunning visuals on a TFT display. In this post, we will walk you through the process of displaying images on a TFT display using an SD card module with Arduino. So let's dive in!

Understanding TFT Displays and SD Card Modules TFT displays

Understanding TFT Displays and SD Card Modules TFT displays are a type of LCD (Liquid Crystal Display) that provide vibrant colors and excellent image quality. On the other hand, an SD card module allows you to read and write data from an SD card. Combining these components offers a powerful solution for displaying images.

Gathering the Required Components

Gathering the Required Components To get started, gather the following components:Arduino board (e.g., Arduino Uno)
TFT display module
SD card module
Jumper wires
SD card containing the images you want to display

Setting Up the Hardware Connection

Setting Up the Hardware Connect the components as follows:Connect the TFT display module to the Arduino board using jumper wires. Make sure to connect the appropriate pins, such as CS (Chip Select), DC (Data/Command), MOSI (Master Out Slave In), SCK (Serial Clock), and RESET.
Connect the SD card module to the Arduino board. Ensure the CS pin of the SD card module is connected to the desired Arduino pin.

Installing the Required Libraries
Installing the Required Libraries To control the TFT display and SD card module, we need to install some libraries. Open the Arduino IDE, go to "Sketch" -> "Include Library" -> "Manage Libraries." Search for and install the following libraries:Adafruit GFX Library
Adafruit ILI9341 Library
SD Library

The Arduino Code Now
Writing the Arduino Code Now, let's write the Arduino code. Open a new sketch in the Arduino IDE and paste the following code

#include <Adafruit_GFX.h>
#include <Adafruit_ILI9341.h>
#include <SPI.h>
#include <SD.h>

#define TFT_CS 10
#define TFT_DC 9
#define SD_CS 4

Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC);
File imageFile;

void setup() {
 tft.begin();
 tft.setRotation(3);

 SD.begin(SD_CS);

 displayImage("image.jpg");
}

void loop() {
 // Additional code, if needed
}

void displayImage(const char* filename) {
 imageFile = SD.open(filename);
 if (imageFile) {
 if (imageFile.isDirectory()) {
 Serial.println("Error: Given file is a directory.");
 imageFile.close();
 return;
 }

 tft.fillScreen(ILI9341_BLACK);

 uint16_t x = 0, y = 0;
 while (imageFile.available()) {
 uint8_t r = imageFile.read();
 uint8_t g = imageFile.read();
 uint8_t b = imageFile.read();

 uint16_t color = tft.color565(r, g, b);
 tft.drawPixel(x, y, color);

 x++;
 if (x >= tft.width()) {
 x = 0;
 y++;
 }
 }

 imageFile.close();
 }
 else {
 Serial.println("Error: Unable to open the file.");
 }
}
