@riknoll wondering if the new grid matrix be used here instead?

I'd love to have a look at it. Where can I find it?

[riknoll]

oh yeah, it totally can! @PasAlt it hasn't been shipped yet but will be on friday. once it's released, i'll give you an example to work off of that shows how to use it

@riknoll Does the pins.setMatrixWidth() do something else than just inform the simulator that it should be displayed as a matrix? So could it have a side effect just to put it like this in my code:

setMatrixWidth(width: number) {
    this._matrixWidth = Math.min(this._length, width >> 0);
    pins.setMatrixWidth(this.pin, this._matrixWidth)
}

I updated the extension to Version 2.1.2 (PasAlt/pxt-neopixel-matrix-extension@6c0d5f2)

Added the pins.setMatrixWidth() to setMatrixWidth(). Updated the tests to reflect it correctly. Updated to version 9.0.2 in pxt.json.

One thing to consider for the future: All of the Neopixels that I used till now were not wired the way the simulator expects it. Normally they are wired in a "snake"format, e.g. first row left to right, then second row right to left, then third row left to right, etc.

@martinwork can you look at the updated extension?

[PasAlt]

@martinwork It is two lines of code. You can find it in this commit: PasAlt/pxt-neopixel-matrix-extension@59a1643
