1) EtherPix library

2) 
3) FlexPix is a large scale display architecure that is driven using UDP/IP.
4) It consists of single pixels that are connected to chains. A number of those
5) pixel chains is then connected to a so called distributor module that
6) receives data over ethernet and distributes it to the pixel chains.
7) 
8) The protocol used on UDP is MCUF (microcontroller unit frame, see
9) http://wiki.blinkenarea.org/index.php/MicroControllerUnitFrame). However,

10) as EtherPix displays can have more than 65536 pixels, multiple MCUF packets

11) are sent for one frame - a single MCUF frame to every distributor.
12) The coordinates of the pixels in the MCUF packets do not correspond to pixel
13) locations, but to pixel addresses. The y coordinate is the number of the
14) output of the distributor and the x coordinate is the number of the pixel
15) in the chain. The number of channels is always 3 (RGB) and the maximum value
16) is always 255 (8 bit per channel).

18) This library can be used to send the required UDP packets to the EtherPix
