"Full 256 color display support"
HOW???
2013-12-26 00:55:00 Hello,
"256" means the value of signal color. not 256 kinds of color.
And the default value is 255(the highest one). it can't be changed.
For example: M.put_char(0,0,'A',NO_ROT,MULTIPLY,RED,TOP_LAYER);
display the A on the TOP layer
there are some sample code on wiki page, you could check it.

You could adjust the color combination to make other color
1 Red
2 Green
3 Blue
4 R+G=Yellow
5 R+B= magenta
6 G+B=cyan
7 R+G+B=white
8 black
Maybe there is a little color difference. But it is fine. Grey.CC

Grey.CC 2013-12-25 02:00:16 I want from this module of 256 colors, but as I understand - it the 8th colors, one of which black.
OE(ED2) pin on TLC5916 - for change to adjust mode.
This is 8-color display, yes?
Excuse for my English - it not native. Constantine

Constantine 2013-12-24 21:38:48 Hello,
For example the value of red is (255,0,0).
You couldn't change the value of "255" to any other number.
Although it can't change the value, it can display the color combination
red,green,blue,red+green,red+blue...
what is your mean of "OE-pin"?
And what you want to do with this module? Grey.CC

The Module supports a Red/Green/Blue full color LED Matrix(single the value is 255).

This valuse is not changed?
How I can receive 256 colors if the OE-pin is soldered on the GND? Constantine

Constantine 2013-12-24 02:25:58 Hello Constantine,
The Module supports a Red/Green/Blue full color LED Matrix(single the value is 255).
And it also supports color combination. like R+G/G+B/R+G+B.
But it can't define the value of every color.
