So our system locked up again. When we follow http://processors.wiki.ti.com/index.php/AM335x_ADC_Driver%27s_Guide
We get: Code hier eingeb machinekit@beaglebone:~# ls -al /sys/bus/iio/devices/iio:device0/ drwxr-xr-x 5 root root 0 Jan 1 00:00 . drwxr-xr-x 4 root root 0 Jan 1 00:00 .. -r--r--r-- 1 root root 4096 Jan 1 00:00 dev -r--r--r-- 1 root root 4096 Jan 1 00:00 in_voltage0_raw -r--r--r-- 1 root root 4096 Jan 1 00:00 in_voltage1_raw -r--r--r-- 1 root root 4096 Jan 1 00:00 in_voltage2_raw -r--r--r-- 1 root root 4096 Jan 1 00:00 in_voltage3_raw -r--r--r-- 1 root root 4096 Jan 1 00:00 in_voltage4_raw -r--r--r-- 1 root root 4096 Jan 1 00:00 in_voltage5_raw -r--r--r-- 1 root root 4096 Jan 1 00:00 in_voltage6_raw -r--r--r-- 1 root root 4096 Jan 1 00:00 in_voltage7_raw -r--r--r-- 1 root root 4096 Jan 1 00:00 name drwxr-xr-x 2 root root 0 Jan 1 00:00 power lrwxrwxrwx 1 root root 0 Jan 1 00:00 subsystem -> ../../../../../../bus/iio -rw-r--r-- 1 root root 4096 Jan 1 00:00 uevent en... So the lines "buffer", "mode" and "scan_elements" are missing. So trying to read a oneshot value gives: machinekit@beaglebone:~# cat /sys/bus/iio/devices/iio\:device0/in_voltage0_raw Resource temporarily unavailable After a "sudo reboot", the "iio:device0" was missing, it came back only after starting machinekit. Now the "in_voltageX_raw" shows the values. Really hope this helps! -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
