Touch Screen: Resistive, supports multi-touch gestures
Driver Board: HDMI and VGA input, compatible with Raspberry Pi boards
Interface: HDMI, VGA, and USB for touch screen control
Power Supply: 5V DC, 2A
Operating Temperature: -20C to 60CCode ExamplesExample 1: Basic Display Test with Raspberry Pi (Python)This example demonstrates how to use the 7inch LCD Touch Screen Display with a Raspberry Pi board to display a simple GUI using Python.Hardware ConnectionConnect the HDMI output of the Raspberry Pi to the HDMI input of the driver board.
Connect the USB cable from the driver board to the Raspberry Pi.
Power on the Raspberry Pi and the display.SoftwareInstall the necessary libraries on your Raspberry Pi:
```
sudo apt-get update
sudo apt-get install python3 python3-pip
pip3 install pygame
```
Create a Python script to display a GUI on the LCD touch screen:
```python
import pygame# Initialize pygame
pygame.init()# Set the display dimensions
width, height = 1024, 600
screen = pygame.display.set_mode((width, height))# Set the title of the window
pygame.display.set_caption('Raspberry Pi LCD Touch Screen Display')# Fill the screen with a black background
screen.fill((0, 0, 0))# Draw a red rectangle on the screen
pygame.draw.rect(screen, (255, 0, 0), (100, 100, 200, 200))# Update the display
pygame.display.flip()# Run the GUI event loop
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
```
Example 2: Touch Screen Calibration with Raspberry Pi (Python)This example demonstrates how to calibrate the touch screen using a Raspberry Pi board and Python.Hardware ConnectionConnect the HDMI output of the Raspberry Pi to the HDMI input of the driver board.
Connect the USB cable from the driver board to the Raspberry Pi.
Power on the Raspberry Pi and the display.SoftwareInstall the necessary libraries on your Raspberry Pi:
```
sudo apt-get update
sudo apt-get install python3 python3-pip
pip3 install pygame evdev
```
Create a Python script to calibrate the touch screen:
```python
import pygame
import evdev# Initialize pygame
pygame.init()# Set the display dimensions
width, height = 1024, 600
screen = pygame.display.set_mode((width, height))# Create an evdev input device object
device = evdev.InputDevice('/dev/input/event0')# Calibration steps
device.grab()
print("Touch the top-left corner of the screen...")
event = device.read_one()
x1, y1 = event.code, event.value
print("Touch the top-right corner of the screen...")
event = device.read_one()
x2, y2 = event.code, event.value
print("Touch the bottom-left corner of the screen...")
event = device.read_one()
x3, y3 = event.code, event.value
print("Touch the bottom-right corner of the screen...")
event = device.read_one()
x4, y4 = event.code, event.value# Calculate the calibration coefficients
x_coeff = (x2 - x1) / (width - 1)
y_coeff = (y4 - y1) / (height - 1)# Print the calibration coefficients
print(f"Calibration coefficients: x={x_coeff}, y={y_coeff}")# Release the device grab
device.ungrab()
```
