Hi experts, i am new to this area, I am using amstrong 3.8.13 kernel in BBB at first i loaded the device tree as below,
echo cape-bone-iio > /sys/devices/bone_capemgr.*/slots then i used analog pins however i am getting the fixed values that is values are not varying continously as i vary input analog voltage if i go to this path /sys/devices/ocp.2/44e0d000.tscadc/tiadc/iio:device0 and then ls -al gives me total 0 drwxr-xr-x 3 root root 0 Jan 1 03:24 . drwxr-xr-x 4 root root 0 Jan 1 03:24 .. -r--r--r-- 1 root root 4096 Jan 1 03:27 dev -rw-r--r-- 1 root root 4096 Jan 1 03:27 in_voltage0_raw -rw-r--r-- 1 root root 4096 Jan 1 03:27 in_voltage1_raw -rw-r--r-- 1 root root 4096 Jan 1 03:27 in_voltage2_raw -rw-r--r-- 1 root root 4096 Jan 1 03:27 in_voltage3_raw -rw-r--r-- 1 root root 4096 Jan 1 03:27 in_voltage4_raw -rw-r--r-- 1 root root 4096 Jan 1 03:27 in_voltage5_raw -rw-r--r-- 1 root root 4096 Jan 1 03:27 in_voltage6_raw -rw-r--r-- 1 root root 4096 Jan 1 03:27 in_voltage7_raw -r--r--r-- 1 root root 4096 Jan 1 03:25 name drwxr-xr-x 2 root root 0 Jan 1 03:27 power lrwxrwxrwx 1 root root 0 Jan 1 03:27 subsystem -> ../../../../../bus/iio -rw-r--r-- 1 root root 4096 Jan 1 03:24 uevent there is no mode directory and buffer directory in list . please help to configure ADC In continous mode.
