hello massimo
thanks for the fast reply - very well for an overworked person 
the usb port isn't useable for debugging? i think this could be a very efficient way to give out some statements. or is only a terminal programm on pc side missing for reading datas?
about the c statements : is there a short example to see the syntax?
where is an information to let the board run standalone?
how can i communicate with flash and max/msp? over midi?
thanks again for an answer
