Code Examples
### Example 1: Displaying Text and Graphics
This example demonstrates how to display text and graphics on the TFT LCD display using the TFTLCD library.
```c++
#include <TFTLCD.h>
TFT_LCD tft = TFT_LCD();
void setup() {
tft.begin(); // Initialize the TFT LCD display
tft.setTextSize(2); // Set the text size to 2
tft.setTextColor(TFT_WHITE, TFT_BLACK); // Set the text color to white on a black background
tft.fillScreen(TFT_BLACK); // Clear the screen with a black background
}
void loop() {
tft.setCursor(0, 0); // Set the cursor to the top-left corner
tft.println("Hello, World!"); // Print a message on the display
// Draw a red rectangle
tft.fillRect(10, 20, 40, 20, TFT_RED);
delay(1000);
// Clear the screen and draw a blue circle
tft.fillScreen(TFT_BLACK);
tft.fillCircle(60, 60, 20, TFT_BLUE);
delay(1000);
}
```
### Example 2: Creating a Simple GUI with Buttons
This example showcases how to create a simple graphical user interface (GUI) with buttons using the TFTLCD library.
```c++
#include <TFTLCD.h>
TFT_LCD tft = TFT_LCD();
int buttonState = 0;
void setup() {
tft.begin(); // Initialize the TFT LCD display
tft.setTextSize(2); // Set the text size to 2
tft.setTextColor(TFT_WHITE, TFT_BLACK); // Set the text color to white on a black background
tft.fillScreen(TFT_BLACK); // Clear the screen with a black background
// Draw three buttons
tft.drawRect(10, 20, 40, 20, TFT_WHITE); // Button 1
tft.drawRect(60, 20, 40, 20, TFT_WHITE); // Button 2
tft.drawRect(110, 20, 40, 20, TFT_WHITE); // Button 3
}
void loop() {
// Read the state of a button (e.g., using a digital input pin)
buttonState = digitalRead(2);
if (buttonState == HIGH) {
// Handle button press event
tft.fillRect(10, 20, 40, 20, TFT_RED); // Highlight Button 1
delay(500);
tft.fillRect(10, 20, 40, 20, TFT_WHITE); // Reset Button 1
}
// Repeat for other buttons...
}
```
