Sample: Animation

Using a WS2812 module arranged in a matrix, you can easily create a small display. Below is an example of connecting a 16x16 matrix module to a Pico board.

The DIN pin of the matrix module is connected to GPIO2.

rect-inflate-16.png is an image file with a square gradually inflating in a 16x16 dot area, arranged horizontally.

Image of rect-inflate-16.png

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

L:/>display-ws2812 setup {din:2 zigzag-nw-vert:16,16} brightness:.1
L:/>draw image-load:rect-inflate-16.png
L:/>draw image {size:16,16}
L:/>draw repeat { image {offset-shift:16,0} sleep:100 }

When you run offset-shift:16,0, the display area shifts 16 dots to the right at a time, creating an animation effect.

The command operations are exactly the same, and you can display various animations just by changing the image file.
