The films are known for having a mind-bending complex plot, and the fourth installment looks to follow up on that tradition starting with the revival of the two iconic characters.įans of the Matrixhave been patiently waiting for this trailer since all the way back to when rumors about this film first emerged. This rotation is not required for NEO_TILE_PROGRESSIVE.The Matrix Resurrectionsdirector Lana Wachowski discussed the idea of bringing both Neo and Trinity back for the upcoming sequel to the iconic Matrix trilogy from the late '90s early 2000s. This is intentional and by design it keeps the tile-to-tile wiring more consistent and simple. BUT…if NEO_TILE_ZIGZAG order is selected, alternate lines of tiles must be rotated 180 degrees. Add either NEO_TILE_PROGRESSIVE or NEO_TILE_ZIGZAG to indicate the order. Add either NEO_TILE_ROWS or NEO_TILE_COLUMNS.įinally, rows or columns of tiles may be arranged in progressive or zigzag order that is, every row or column proceeds in the same order, or alternating rows/columns switch direction. Again this is independent of the pixel order within the tiles. Tiles can be arranged in horizontal rows or vertical columns. This is independent of the position of the first pixel within the tiles they can be different corners. Add either NEO_TILE_TOP or NEO_TILE_BOTTOM and NEO_TILE_LEFT or NEO_TILE_RIGHT to indicate the position of the first tile.

The first tile must be located at one of the four corners. An additional set of symbols work similarly to then describe the tile order. The NEO_MATRIX_* symbols work the same as in the prior single-matrix case, and now refer to the individual sub-matrices within the overall display. As before, we add up a list of symbols to produce a single argument describing the display format. This is now doubled - similar information is needed both for the pixel order within the individual tiles, and the overall arrangement of tiles in the display. With a single matrix, there was a starting corner, a major axis (rows or columns) and a line sequence (progressive or zigzag).

The second-to-last argument though…this gets complicated… The last argument also follows prior behaviors, and in most cases can be left off. The fifth argument is the pin number, same as before and as with the NeoPixel library. The dimensions of the overall display then will always be a multiple of the sub-matrix dimensions. The next two arguments are the number of tiles, in the horizontal and vertical direction. The first two arguments are the width and height, in pixels, of each tiled sub-matrix, not the entire display. Coordinate (0,0) for drawing graphics will always be at the top-left, regardless of the actual position of the first NeoPixel. The point of this setup is that the rest of the sketch never needs to think about the layout of the matrix.
NEO MATRIX CODE
In the majority of cases with the latest NeoPixel products, you can simply leave this argument off…the example code is just being extra descriptive. The last argument is exactly the same as with the NeoPixel library, indicating the type of LED pixels being used. NEO_MATRIX_TOP + NEO_MATRIX_RIGHT + NEO_MATRIX_COLUMNS + NEO_MATRIX_PROGRESSIVE These values are all added to form a single value as in the above code. The row/column arrangement is indicated by further adding either NEO_MATRIX_COLUMNS or NEO_MATRIX_ROWS to either NEO_MATRIX_PROGRESSIVE or NEO_MATRIX_ZIGZAG. The first pixel must be at one of the four corners which corner is indicated by adding either NEO_MATRIX_TOP or NEO_MATRIX_BOTTOM to either NEO_MATRIX_LEFT or NEO_MATRIX_RIGHT. This indicates where the first pixel in the matrix is positioned and the arrangement of rows or columns. The next argument is the interesting one.
NEO MATRIX FREE
On the shield this is hard-wired to digital pin 6, but standalone matrices are free to use other pins. The third argument - 6 - is the pin number to which the NeoPixels are connected. The first two arguments - 5 and 8 - are the width and height of the matrix, in pixels.
