Hi m.a.r.v.i.n

thanks for the reply, i will take a look if with that init values and that interrupt setting/handler (i guess?) get the new asuro lib working with Ultraschall

and else perhaps with a #ifdef #else construct

(the problem is that im quite a newbie when it comes to AVR programming and C in general, i guess #ifdef #else would be easiest at first)

greetings,
dopez
