Manage OLED Services

In the factory image, the OLED service starts automatically at boot. Under normal circumstances, no management is needed. Just keep it set to auto-start.

Stop the Service

Stop the service:

xxxxxxxxxx
sudo systemctl stop yahboom_oled.service

Permanently disable the service:

xxxxxxxxxx
sudo systemctl disable yahboom_oled.service

Check the service status:

xxxxxxxxxx
sudo systemctl status yahboom_oled.service

Start the Service

Start the service:

xxxxxxxxxx
sudo systemctl start yahboom_oled.service

Restart the service:

xxxxxxxxxx
sudo systemctl restart yahboom_oled.service

Enable the service to auto-start at boot:

sudo systemctl enable yahboom_oled.service
