LCD Bitmap Converter Online

Are you working with microcontrollers and need a tool to design custom LCD bitmaps? Look no further! Our LCD Bitmap Generator is an intuitive tool allowing users to create, preview, and generate bitmap arrays for LCDs commonly used in embedded systems. Whether you’re prototyping or preparing for production, this tool simplifies the entire process.





Key Features of the LCD Bitmap Tool

  1. Interactive Pixel Grid
    The tool features a grid-based interface that allows you to draw pixel-perfect designs for your LCD. Each pixel can be toggled on or off with a simple click, enabling precise control over your design.
  2. Customizable Resolutions
    Set the horizontal and vertical pixel counts to match your specific LCD resolution. The tool supports a wide range of resolutions, including:

    • 128×64: Commonly used in monochrome graphical LCDs.
    • 160×128: Popular in color LCDs with higher detail requirements.
    • 320×240: Ideal for larger graphical LCDs.
  3. Upload and Convert Images
    Have an existing image you’d like to use? The tool includes an option to upload an image, which it converts into a bitmap representation on the grid. You can preview and tweak the converted design before generating the output.
  4. C/C++ Array Generation
    Once your design is complete, the tool generates a C or C++ array in hexadecimal format, ready to paste into your firmware code. Each pixel state (on/off) is represented in a compact, memory-efficient format.
  5. Copy to Clipboard
    Quickly copy the generated code to your clipboard with a single click, thanks to the integrated “Copy” button with FontAwesome styling for visual appeal.

How to Use the LCD Bitmap Tool

  1. Set the Resolution 
    Input your LCD’s horizontal and vertical pixel counts in the provided fields. Click the “Set Resolution” button to adjust the grid to your desired dimensions.
  2. Select Mode
    Choose between monochrome or color TFT LCDs
  3. Design Your Bitmap
    Use the pixel grid to draw your design. Click on any square to toggle its state (on/off). The grid instantly updates, giving you a live preview of your bitmap.
  4. Optional: Upload an Image
    If you have a pre-existing image, upload it to the tool. It will convert the image into a bitmap format that matches your resolution. Edit the result directly on the grid if needed.
  5. Generate the Code
    Once your design is ready, click the “Generate” button. The tool will output a C/C++ array formatted as:

    const uint8_t bitmap[] = { 0xFF, 0x81, 0x81, 0xFF, // Example output for a 4x4 grid };
  6. Copy and Paste
    Click the “Copy” button to copy the generated code to your clipboard. Paste it into your firmware project, and you’re ready to program your LCD.

Supported LCD Types

The tool is versatile and supports various LCD modules typically used with microcontrollers, such as:

  • Monochrome LCDs:
    Suitable for resolutions like 128×64 or 240×64, used in devices such as industrial displays or IoT projects.
  • TFT Color LCDs:
    Works with popular 160×128 or 320×240 TFT displays, perfect for more complex GUIs.
  • OLED Displays:
    Compatible with OLED screens that use bitmap graphics, such as 128×32 or 128×64 resolutions.

Why Use This Tool?

This tool was designed with embedded developers in mind. Its straightforward interface reduces the time and effort required to create custom LCD graphics. Providing a seamless workflow from design to implementation eliminates the need for external software or complex image-to-bitmap conversion utilities.

Whether you’re building an IoT dashboard, a handheld device, or a custom electronic project, this tool is your go-to solution for generating high-quality bitmap arrays.
