Sample: Illumination

By changing the image file contents or the amount of movement of the display area, you can display various illumination patterns.

hue-256-vert.png is an image with a 256-color hue gradient arranged vertically.

Image of hue-256-vert.png

Save this file to the Pico board's internal storage L: drive and run the following commands:

L:/>display-ws2812 setup {din:2 straight:60} brightness:.1
L:/>draw image-load:hue-256-vert.png
L:/>draw image {size:8,1 repeat-x}
L:/>draw repeat { image {offset-shift:1,1} sleep:100 }

When you run offset-shift:1,1, the display area shifts diagonally down to the right, so the hue changes as the dot flows.

By changing the vertical shift amount in offset-shift, such as offset-shift:1,2, you can make the hue change faster.
