4. የማዋቀር መመሪያ
Follow these steps carefully to connect and configure your Waveshare 7-inch DPI Display with your Raspberry Pi.
4.1 አካላዊ ግንኙነት
- Prepare the FFC Cable: Gently insert one end of the 50-pin FFC cable into the JP2 connector (drawer socket) on the display's small adapter board. Ensure the cable is fully seated and then close the drawer socket to secure it.
- Connect to RGB LCD HAT: Insert the other end of the 50-pin FFC cable into the connector on the RGB LCD HAT. This is typically a turn-cover socket; lift the cover, insert the cable, and then press the cover down to lock it.
- Attach RGB LCD HAT to Raspberry Pi: Carefully align the 40-pin GPIO header of the RGB LCD HAT with the GPIO pins on your Raspberry Pi board. Press down gently but firmly to ensure a secure connection.
- Mount the Display (Optional): If using the adjustable metal stand, attach the display to the stand as shown in the product images. This provides a stable viewአንግል።
- አብራ፡ Connect a 5V/3A power supply to your Raspberry Pi. The display will draw power directly from the Pi's GPIO pins.
