Hello Miroslav,
Thanks for the help, you are right there the TI adc driver was hidden.
Now I have a directory called /sys/bus/iio/devices/ but further nothing. This directory is completly empty.
When I type: ls -al /sys/bus/iio/devices/iio\:device0/ from the root I get an error that there no such file or directory.
Must I do something else?
Kind regards
Patrick
