4.2 Hugbúnaðarstilling

For the display to function correctly, you may need to modify the config.txt file on your Raspberry Pi's boot partition. This typically involves setting the correct resolution and DPI interface parameters. Refer to the official Waveshare online user manual for specific configuration lines for your Raspberry Pi model and OS version.

Athugið: Incorrect configuration in config.txt is a common cause for display issues such as a black screen or no image. Always back up your config.txt before making changes.

5. Notkunarleiðbeiningar

5.1 Baklýsingastýring

The display features backlight control to manage power consumption. Specific methods for controlling the backlight (e.g., via software commands or physical jumpers) may vary. Consult the Waveshare online documentation for detailed instructions relevant to your setup.

6. Viðhald

Til að tryggja endingu og bestu mögulegu virkni skjásins skaltu fylgja þessum viðhaldsleiðbeiningum:

  • Þrif: Use a soft, lint-free cloth to gently wipe the screen surface. For stubborn smudges, slightly dampÞurrkið klútinn með vatni eða skjáþolnu hreinsiefni. Forðist sterk efni eða slípiefni.
  • Meðhöndlun: Handle the display by its edges. Avoid applying pressure directly to the screen surface or the FFC cable.
