Neopixel matrix width
For Neopixel matrix (strip) on the specified pin, set the width of that matrix. This informs the simulator to display the Neopixel strip as a matrix.
pins.setMatrixWidth(Digital.P1, 16)
Parameters
name: The @boardname@ hardware pin to configure (P0-P20)width: a number (for example, from2through16)
Example
To use the example below, you should add the Neopixel extension to your
project and then copy the JavaScript code below over to your project.
The example creates a strip of 25 neopixels corresponding to a 5x5 matrix and then draws
an X on the matrix. Try changing the value of the variable width
to get matrices of different sizes.
let width = 5
let strip = neopixel.create(DigitalPin.P1, width * width, NeoPixelMode.RGB)
strip.setMatrixWidth(width)
pins.setMatrixWidth(DigitalPin.P1, width)
for (let i = 0; i <= width - 1; i++) {
strip.setMatrixColor(i, i, neopixel.colors(NeoPixelColors.Red))
strip.setMatrixColor(width - (i + 1), i, neopixel.colors(NeoPixelColors.Blue))
}
strip.show()
