im getting nothing.. no errors. but it wont write the file either :(
im pretty new to BBB, its just my 5th day of using it... and I did some
googling, couldn't find a solution yet..
im using *"echo cape-bone-iio > /sys/devices/bone_capemgr.9/slots" *to
create the file for ADC. right now i have to execute the bash command
manually before i execute the c++ file which I wrote to read ADC values
