The second-to-last argument though…this gets complicated…

With a single matrix, there was a starting corner, a major axis (rows or columns) and a line

sequence (progressive or zigzag). 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. As before,

we add up a list of symbols to produce a single argument describing the display format.

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. All tiles must follow the same format. An additional

set of symbols work similarly to then describe the tile order.

The first tile must be located at one of the four 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. This is independent of the position of the first pixel within the tiles; they can be different

corners.

Tiles can be arranged in horizontal rows or vertical columns. Again this is independent of the pixel

order within the tiles. Add either NEO_TILE_ROWS or NEO_TILE_COLUMNS.

Finally, 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. Add either

NEO_TILE_PROGRESSIVE or NEO_TILE_ZIGZAG to indicate the order. BUT…if

NEO_TILE_ZIGZAG order is selected, alternate lines of tiles must be rotated 180 degrees. This is

intentional and by design; it keeps the tile-to-tile wiring more consistent and simple. This rotation is

not required for NEO_TILE_PROGRESSIVE.

Tiles don’t need to be square! The above is just one possible layout. The display shown at the top of
