Software Settings
After hardware connection, software configuration is required for optimal performance. It is recommended to use the official Raspberry Pi OS system version Bookworm.
- Flash Raspberry Pi OS:
- Connect the TF card to your computer using a card reader.
- Use the Raspberry Pi Imager tool to write the Raspberry Pi OS image (Bookworm recommended) to the TF card.
- During the flashing process, you can configure hostname, username, password, and Wi-Fi settings.
- After flashing, safely eject the TF card and insert it into your Raspberry Pi.
- Modify
config.txt:- Access the
config.txtfile in the root directory of the TF card. - Add the necessary configuration code for the DSI display to the end of the file and save. Specific code can be found on the Waveshare Wiki page for your model.
