🛠 Hardware Used

  • SBC: Raspberry Pi 5 (4GB)
  • Display: Waveshare 7" DSI (800x480) Touchscreen
  • Cables & Connectors: Official Raspberry Pi DSI cable

🔧 Setup Instructions

1️⃣ Configure the config.txt:

Connect to Raspberry Pi through SSH via PuTTY

  1. Install PuTTY on your desktop.
  2. Before getting IP address, make sure to power on Raspberry Pi.
  3. Get Angry IP Scanner to find your Pi's IP address.
  4. Enter 'Username' and 'Password' to enter the SSH terminal.

Enable DSI Display:

  1. Open terminal in PuTTY:
For Raspberry Pi 5 Only:
sudo nano /boot/firmware/config.txt
For Raspberry Pi other than 5:
sudo nano /boot/config.txt
  1. Add or modify the following lines: 
    dtoverlay=vc4-kms-v3d
#For connecting in DSI1 uncomment next line 
dtoverlay=vc4-kms-dsi-7inch
#For connecting in DSI0 uncomment next line
#dtoverlay=vc4-kms-dsi-7inch,dsi0
  2. Save and exit (CTRL+X, then Y and Enter).
  3. Reboot the system: 
    sudo reboot

2️⃣ Connect the Hardware:

  1. Attach the Waveshare 7" DSI screen to the Raspberry Pi using the DSI ribbon cable.
  2. Ensure the screen is powered via the Raspberry Pi by connecting the 5V and GND to Raspberry Pi's GPIO.
  3. If not sure what pins to connect, visit pinout for reference.

3️⃣ Touchscreen Calibration (Completely Optional):

For better touchscreen accuracy, install the xinput calibration tool:

sudo apt install xinput-calibrator

📝 NOTE:

DO NOT TOUCH THE SCREEN while the Raspberry Pi is booting via the DSI display. It will prevent the touchscreen feature to work properly.
