Hi all,
A couple of months ago I bought this (nameless) 74HC595 regulated 16x16 dot led matrix board. When the demo script is run, nice Chinese character (s) (?) is/are displayed that scroll in the direction of the arrow. Obviously one of the short sides must be top or bottom. The wiring is such that it is easy to place multiple 16x16's next to each other, long sides side by side. No confusion with that.
A nice character set for similar boards is Nathan Bayer's "Dot Monoco" by Nathan Bayer (created for the Wrobot 16x16 dot led Arduino compatible board) (http://prettyuglycode.net/16X16_font.pdf)
The characters of Nathan's Monoco set scroll in the direction of the arrow, but they appear on this board as kind of mirror image characters or anyway they llok interlaced with empty horizontal lines. Slight incompaticibility. This makes me suspect that this board scrolls from right to left and that the short edge, closest to the arrow/text "scrolling", may be "top". I don't know what is up or down from the Chinese character because I am unfamiliar with Chinese. Do Chinese ticker texts scroll from right to left?
I saw the same board on 16x16 Dot Matrix LED Display Module - ElectroDragon
Who can help me out: which short side should be considered top, bottom of this board? Thanks a lot in advance, Floris
