ADconveter

I am testing the Beaglebone black C and LCD 4DCAPE-70T that provides touch panel. I am eager to use ADconveters on the BBB. But the touch panel can not work well when AD convters work. Sometimes CPU halts at all.

For example

root@beaglebone: ~# echo cape-bone iio>/sys/devices/bone_capemgr.*/slots

root@beaglecone:~# cat /sys/devices/ocp./helper./AIN4

1683

root@beaglebone:~# cat /sys/bus/iio/devices/iio! :device*/in_voltage7_raw

3829

root@beaglebone:~#

If the above command is executed, the touchpanel work very slowly and CPU holts at all. Please give me solution.
