Heya Folks,
      Well Owen you need to elaborate more what exactly you want to 
do with Manchester coding. Ofcourse i mean what type of hardware you 
will use and what is the date rate etc.. 
Any way in the case of Manchester coding a Manchester 1 is a 1 to 0 
transition, while a Manchester 0 is a 0 to 1 transition.
[ http://www.grantronics.com.au/serialformats.html ] And  [ 
http://www.erg.abdn.ac.uk/users/gorry/course/phy-pages/man.html ]. 
You can have a look at avrfreks.net [ http://avrfreaks.net/index.php?
name=PNphpBB2&file=viewtopic&t=35633&highlight=manchester&sid=2fe2f01
a03810ccfc93072a562f3f222 ] here you can see little source examples 
to implement this coding.

Hope it helps.
