5. Oppsett og installasjon

5.1 Fysisk tilkobling

To connect the display to your Raspberry Pi, align the 26-pin header on the display with the corresponding GPIO pins on your Raspberry Pi. Gently press down to ensure a secure connection. Use the provided mounting hardware (standoffs and screws) to firmly attach the display to the Raspberry Pi, if desired, for a stable assembly.

5.2 Driverinstallasjon

The LCD requires a driver to function correctly. Waveshare provides drivers compatible with Raspbian, Ubuntu, Kali, and Retropie systems. Please refer to the official Waveshare documentation or product page for the most up-to-date driver installation instructions specific to your Raspberry Pi model and operating system. Typically, this involves downloading a script and running it on your Raspberry Pi to configure the display and touch functionality.

Note: Incorrect driver installation can lead to display issues. Follow the official guides carefully.

Key Pin Functions:

• 5V: Power positive (5V input).
• GND: Jordforbindelse.
• TP_IRQ: Touch panel interrupt, active low when the panel is touched.
• første: Reset pin.
• LCD_RS: LCD command control / data selection.
• LCD_SI / TP_SI: LCD display / Touch panel SPI data in.
• TP_SO: Touch panel SPI data out.
• LCD_SCK / TP_SCK: LCD display / Touch panel SPI clock.
• LCD_CS: LCD chip selection, active low.
• TP_CS: Touch panel chip selection, active low.
• KEY1/KEY2/KEY3: User-programmable keys.

7. Bruksanvisning

7.1 Skjermbetjening

Once the drivers are correctly installed and the Raspberry Pi is powered on, the display should automatically initialize and show the graphical interface of your operating system. The FBCP (Framebuffer Copy) software driver allows for flexible display management, including setting custom resolutions and enabling dual-screen setups if you have another display connected.
