2. Software Configuration
For the LCD to function correctly, specific drivers must be installed on your Raspberry Pi's operating system. Waveshare provides drivers compatible with Raspbian, Ubuntu, and Kali distributions.
It is highly recommended to use the official Waveshare provided image for initial testing, as it comes pre-configured with the necessary drivers. If you are using your own Raspbian/Ubuntu/Kali image, you will need to install the drivers manually.
Refer to the quick start sheet included in your package or the official Waveshare documentation for detailed driver installation instructions. Incorrect driver installation can lead to display issues.
Operating Instructions
Once the hardware is connected and software drivers are installed, the display will function as a primary or secondary display for your Raspberry Pi.
Using the Touch Function
The 3.5-inch LCD features a resistive touch screen. Use the provided touch pen or a similar stylus for optimal interaction. Avoid using sharp objects or excessive force, as this may damage the screen.

The touch functionality allows for direct interaction with the operating system, enabling tasks such as navigating menus, opening applications, and using a software keyboard for input without requiring an external keyboard or mouse.
Dual-Display Setup (FBCP)
The display supports FBCP (Framebuffer Copy) software drivers, which allows for configuring software resolution and setting up a dual-display environment. This feature enables the content from the primary display to be mirrored or extended to the 3.5-inch LCD.
Configuration details for FBCP are typically found within the driver installation guide provided by Waveshare. This advanced setup allows for flexible display management in various applications.
Maintenance
Proper maintenance ensures the longevity and optimal performance of your Waveshare LCD.
- Cleaning: Use a soft, lint-free cloth slightly dampened with water or a screen cleaner to wipe the display surface. Avoid abrasive materials or harsh chemicals.
- Handling: Always handle the LCD by its edges. Avoid touching the display surface directly with fingers to prevent smudges.
- Storage: When not in use, store the LCD in a dry, dust-free environment, preferably in its original packaging or an anti-static bag.
- Environmental Conditions: Operate the display within its specified temperature and humidity ranges to prevent damage.
