Thanks for your answer. But i don´t know, how this structure or command write. I work with AVR microprocessor, no with linux. Can you send me some examples of command, which I solve my problem? . I need only number with range 0-4000 from 0-1,8V (AIN0). I use machinekit,debian 3.8. and beagle bone black (own cape).Thanks
