In this article, we’ll dive into the world of graphic LCD displays and explore the ins and outs of interfacing the WDG0151-TMI-v-Winstar module. Buckle up, and let’s get started!

What is a Graphic LCD Display?

A graphic LCD display is a type of liquid crystal display (LCD) that allows for the display of complex graphics, text, and images. Unlike character LCD displays, which are limited to displaying pre-defined characters and symbols, graphic LCD displays can display a wide range of graphics and content.

Why Choose the WDG0151-TMI-v-Winstar Module?

The WDG0151-TMI-v-Winstar module is a popular choice among microcontroller enthusiasts and professionals due to its high-quality display, ease of use, and versatility. This module features a 1.5-inch, 128×128 pixel graphic LCD display with a built-in controller, making it easy to interface with a wide range of microcontrollers.

Hardware Requirements

Before we dive into the world of graphic LCD displays, let’s take a look at the hardware requirements needed to get started:

• WDG0151-TMI-v-Winstar graphic LCD display module
• Microcontroller of your choice (e.g., Arduino, Raspberry Pi, ESP32, etc.)
• Breadboard and jumper wires
• Power supply (e.g., batteries, wall adapter, etc.)

Connecting the WDG0151-TMI-v-Winstar Module

Now that we have our hardware requirements in place, let’s take a look at how to connect the WDG0151-TMI-v-Winstar module to our microcontroller:

The WDG0151-TMI-v-Winstar module has a total of 20 pins, which can be divided into three categories:

Power Pins

• VCC: 5V power supply
• GND: Ground

Control Pins

• RS: Register Select (data or command)
• RW: Read/Write (data or command)
• EN: Enable (clock signal)

Data Pins

• D0-D7: 8-bit data bus

Connect the power pins (VCC and GND) to your power supply, and the control pins (RS, RW, and EN) to your microcontroller’s digital pins. The data pins (D0-D7) should be connected to your microcontroller’s data pins.

Programming the WDG0151-TMI-v-Winstar Module

Now that we have our hardware connected, let’s take a look at how to program the WDG0151-TMI-v-Winstar module using a microcontroller.

Initializing the Display

The first step in programming the WDG0151-TMI-v-Winstar module is to initialize the display. This involves sending a series of commands to the display to set its operating mode, clear the display, and set the display’s contrast.

  
  void setup() {
    // Initialize the display
    lcd_init();
  }

  void lcd_init() {
    // Set the display's operating mode
    lcd_command(0x01);
    delay(10);

    // Clear the display
    lcd_command(0x01);
    delay(10);

    // Set the display's contrast
    lcd_command(0x53);
    delay(10);
  }

  void lcd_command(uint8_t command) {
    // Set the RS pin low (command mode)
    digitalWrite(RS, LOW);

    // Send the command
    for (int i = 0; i < 8; i++) {
      digitalWrite(D0 + i, (command >> i) & 0x01);
    }

    // Pulse the EN pin high (clock signal)
    digitalWrite(EN, HIGH);
    delayMicroseconds(1);
    digitalWrite(EN, LOW);
    delayMicroseconds(1);
  }
  

Displaying Graphics and Text

Now that we have our display initialized, let’s take a look at how to display graphics and text on the WDG0151-TMI-v-Winstar module.

  
  void loop() {
    // Display a graphic image
    lcd_display_image(graphic_image, 128, 128);

    // Display some text
    lcd_display_text("Hello, World!", 10, 20);
  }

  void lcd_display_image(uint8_t *image, uint8_t width, uint8_t height) {
    // Set the RS pin high (data mode)
    digitalWrite(RS, HIGH);

    // Send the image data
    for (int i = 0; i < width * height; i++) {
      for (int j = 0; j < 8; j++) {
        digitalWrite(D0 + j, (image[i] >> j) & 0x01);
      }

      // Pulse the EN pin high (clock signal)
      digitalWrite(EN, HIGH);
      delayMicroseconds(1);
      digitalWrite(EN, LOW);
      delayMicroseconds(1);
    }
  }

  void lcd_display_text(char *text, uint8_t x, uint8_t y) {
    // Set the RS pin high (data mode)
    digitalWrite(RS, HIGH);

    // Send the text data
    for (int i = 0; i < strlen(text); i++) {
      for (int j = 0; j < 8; j++) {
        digitalWrite(D0 + j, (text[i] >> j) & 0x01);
      }

      // Pulse the EN pin high (clock signal)
      digitalWrite(EN, HIGH);
      delayMicroseconds(1);
      digitalWrite(EN, LOW);
      delayMicroseconds(1);
    }
  }
  

Tips and Tricks
