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*
<wlmailhtml:{DBC1F00B-A137-4BB0-B443-EB0C887D507B}mid://00000002/!x-usc:mailto:root@beaglebone>:
~# echo cape-bone iio>/sys/devices/bone_capemgr.*/slots
*root@beaglecone:~# cat*
<wlmailhtml:{DBC1F00B-A137-4BB0-B443-EB0C887D507B}mid://00000002/!x-usc:mailto:root@beaglecone:~#%20cat>
/sys/devices/ocp.*/helper.*/AIN4

*root@beaglebone:*
<wlmailhtml:{DBC1F00B-A137-4BB0-B443-EB0C887D507B}mid://00000002/!x-usc:mailto:root@beaglebone>~#
cat /sys/bus/iio/devices/iio! :device*/in_voltage7_raw
3829
*root@beaglebone:~#*
<wlmailhtml:{DBC1F00B-A137-4BB0-B443-EB0C887D507B}mid://00000002/!x-usc:mailto:root@beaglebone:~#>
If the above command is executed, the touchpanel work very slowly and CPU
holts at all. Please give me solution.
