Hey guys,
I recently got a core and loving most of the features. Pre-ordered some Photons too :).
I’ve been trying to use the core to replicate some Arduino functionality I have to draw a 16 x 16 smily face on a NeoMatrix panel which is basically a 16 x 16 neopixel panel.
I found an awesome NeoMatrix library that somebody gratiously ported to the core but have been having immense issues either importing or using it.
The NeoMatrix port is here: https://github.com/delianides/SparkCore-NeoMatrix
I apologize for the code bomb below but don’t know how else to show it. I’m still a super newbie with the core and the WebIde (used to vim coding) and I guess my first problem is if the NeoMatrix port is even available to my script once i’ve imported it.
I’d like to use this to be able to make a RESTFUL upload of my 16x16 gif or animated gif and then spit out the RGB arrays and have them render on the core. Something I wouldn’t be able to do on an Arduino unless I dealt with Firmata stuff.
The code:
/*-------------------------------------------------------------------------
Spark Core library to control WS2811/WS2812 based RGB
LED devices such as Adafruit NeoPixel strips and matrices.
Currently handles 800 KHz and 400kHz bitstream on Spark Core,
WS2812, WS2812B and WS2811.
Also supports Radio Shack Tri-Color Strip with TM1803 controller
400kHz bitstream.
PLEASE NOTE that the NeoPixels require 5V level inputs
and the Spark Core only has 3.3V level outputs. Level shifting is
necessary, but will require a fast device such as one of the following:
[SN74HCT125N]

http://www.digikey.com/product-detail/en/SN74HCT245N/296-1612-5-ND/277258
[TXB0108PWR]
http://www.digikey.com/product-search/en?pv7=2&k=TXB0108PWR
If you have a Spark Shield Shield, the TXB0108PWR 3.3V to 5V level
shifter is built in.

// MATRIX DECLARATION:
// Parameter 1 = width of EACH NEOPIXEL MATRIX (not total display)
// Parameter 2 = height of each matrix
// Parameter 3 = number of matrices arranged horizontally
// Parameter 4 = number of matrices arranged vertically
// Parameter 5 = pin number (most are valid)
// Parameter 6 = matrix layout flags, add together as needed:
// NEO_MATRIX_TOP, NEO_MATRIX_BOTTOM, NEO_MATRIX_LEFT, NEO_MATRIX_RIGHT:
// Position of the FIRST LED in the FIRST MATRIX; pick two, e.g.
// NEO_MATRIX_TOP + NEO_MATRIX_LEFT for the top-left corner.
// NEO_MATRIX_ROWS, NEO_MATRIX_COLUMNS: LEDs WITHIN EACH MATRIX are
// arranged in horizontal rows or in vertical columns, respectively;
// pick one or the other.
// NEO_MATRIX_PROGRESSIVE, NEO_MATRIX_ZIGZAG: all rows/columns WITHIN
// EACH MATRIX proceed in the same order, or alternate lines reverse
// direction; pick one.
// NEO_TILE_TOP, NEO_TILE_BOTTOM, NEO_TILE_LEFT, NEO_TILE_RIGHT:
// Position of the FIRST MATRIX (tile) in the OVERALL DISPLAY; pick
// two, e.g. NEO_TILE_TOP + NEO_TILE_LEFT for the top-left corner.
// NEO_TILE_ROWS, NEO_TILE_COLUMNS: the matrices in the OVERALL DISPLAY
// are arranged in horizontal rows or in vertical columns, respectively;
// pick one or the other.
// NEO_TILE_PROGRESSIVE, NEO_TILE_ZIGZAG: the ROWS/COLUMS OF MATRICES
// (tiles) in the OVERALL DISPLAY proceed in the same order for every
// line, or alternate lines reverse direction; pick one. When using
// zig-zag order, the orientation of the matrices in alternate rows
// will be rotated 180 degrees (this is normal -- simplifies wiring).
// See example below for these values in action.
// Parameter 7 = pixel type flags, add together as needed:
// NEO_RGB Pixels are wired for RGB bitstream (v1 pixels)
// NEO_GRB Pixels are wired for GRB bitstream (v2 pixels)
// NEO_KHZ400 400 KHz bitstream (e.g. FLORA v1 pixels)
// NEO_KHZ800 800 KHz bitstream (e.g. High Density LED strip)
// For Spark Core developement it should probably also be WS2812B if you're
// using adafruit neopixels.
// Example with three 10x8 matrices (created using NeoPixel flex strip --
// these grids are not a ready-made product). In this application we'd
// like to arrange the three matrices side-by-side in a wide display.
// The first matrix (tile) will be at the left, and the first pixel within
// that matrix is at the top left. The matrices use zig-zag line ordering.
// There's only one row here, so it doesn't matter if we declare it in row
// or column order. The matrices use 800 KHz (v2) pixels that expect GRB
// color data.

It’s almost like the library wasn’t imported or loaded properly and i’m at a loss for how to make the GFX and NEOMATRIX stuff available to my folder and how to just include them with the Web Ide mechanism.
