Inconsistency: Documentation and Code #2

Hello,

Correct me if I'm wrong, but your code starts with bytes filled with 255. This is eight ones and not seven ones in binary and you're not clearing the LSB as documented here: http://protocoljura.wiki-site.com/index.php/Protocol_to_coffeemaker


Besides this, can someone help me getting it to work with a Jura Impressa 500? It seems to have a additional wire for synchronous data transfer as shown here: http://www.juradiy.de/Logik_Impressa_500.pdf
