Just a wee thank you to all those (Jay & Steve in particular) who helped to find a maximum and made my thesis a success. My chief is "...very pleased with the result." and so am I.
Just have to debug now the bloody report - which is not going to be easy ;-).

Viele Gruesse,

Klaus

PS: If anybody is interested in a report on "Microcontroller guided fiber coupling" + assembler code, I will gladely send it out to him once its handed in - in return I just expect some criticism on it.
