3.2. Softwarekonfiguration
To enable the display and touch functionality, specific drivers are required. Waveshare provides drivers compatible with various Raspberry Pi operating systems, including Raspbian, Ubuntu, Kali, and Retropie. Refer to the official Waveshare product page or documentation for detailed instructions on driver installation for your specific OS. The display also supports FBCP (Frame Buffer Copy) software drivers, which allow for flexible configuration of software resolution and the setup of dual-display environments.
After installing the drivers, you may need to configure the system to output to the SPI display. This typically involves modifying configuration files (z. B. /boot/config.txt) to enable SPI and set the correct display parameters. Detailed steps are available in the Waveshare documentation.
4. Bedienungsanleitung
4.1. Grundlegende Bedienung
The 3.5-inch LCD features resistive touch control. Use the provided touch pen or a gentle finger press to interact with the screen. Resistive touch screens respond to pressure, so a light but firm touch is usually sufficient. Calibration may be required after initial setup to ensure accurate touch response.
