An offline image gallery that switches between five jpg images.
|
|
|
|
Copy images into the root of your Pico's flash using Thonny.
|
|
|
|
If you want to use your own images they must be the screen dimensions
|
|
(or smaller) and saved as *non-progressive* jpgs.
|
|
|
|
Make sure to uncomment the correct size for your display!
