Hello,
To rotate your DAKboard display on a Raspberry Pi 3B running RuneAudio, follow these steps:
1. Edit the config.txt File:
You mentioned already adding display_rotate=1 to /boot/config.txt. This setting should indeed rotate the display to portrait mode. The values are:
0 = normal
1 = 90 degrees
2 = 180 degrees
3 = 270 degrees
Make sure you save the file after editing. To do this correctly, you can use:
- Code: Select all
bash
sudo nano /boot/config.txt
Add the line if it's not there, or ensure it's correctly set:
- Code: Select all
bash
display_rotate=1
2. Reboot the Raspberry Pi:
After saving the changes, reboot the Pi for the changes to take effect:
- Code: Select all
bash
sudo reboot
