# LCD Control
|
|
|
|
The below will setup an Adafruit mini LCD with 2 buttons as a controller for selecting which photo albums are displayed on a PiFrame. This setup also includes the Adafruit stemma/qwiic LUX sensor setup which will be integrated further in the future.
|
|
|
|
Please note:
|
|
- Single button presses need about 1/4 of a second to register
|
|
- Holding 'Up' for at least 3 seconds will trigger a prompt to reboot
|
|
- Holding 'Down' for at least 3 seconds will trigger a prompt to power off
|
|
- If you hold 'Down' on the reboot or power off prompts a debug menu will be displayed
