After reboot, command line: cat
/sys/bus/iio/devices/iio:device0/in_voltage0_raw works fine and returns
correct 0-4095 ADC values. But as soon as I try to read those values from
a compiled C program I get the "Resource temporarily unavailable" error
response. After giving up on open() and fopen() C commands I've reverted
to:
Enter code here...
{value= system("cat /sys/bus/iio/devices/iio:device0/in_voltage0_raw");}
And after that the manual read in linux command line, cat
/sys/bus/iio/devices/iio:device0/in_voltage0_raw, fails the same way:
"Resource temporarily unavailable"
my "uname -a" returns: Linux arm 4.14.108-ti-r104 #1 SMP PREEMPT Tue Apr 9
18:45:06 UTC 2019 armv7l armv7l armv7l GNU/Linux
