Anyone have any advice on why I can't seem to read the ADC? Thanks!
--------------
What am I missing here?
# uname -r
3.8.13-bone72
# pwd
/sys/bus/iio/devices/iio:device0
# ls
dev in_voltage0_raw in_voltage1_raw in_voltage2_raw name power/
subsystem@ uevent
# cat in_voltage0_raw
cat: in_voltage0_raw: Device or resource busy
The fragment from my DTBO:
fragment@6 {
target = <&tscadc>;
__overlay__ {
status = "okay";
adc {
ti,adc-channels = <0 1 2>;
};
};
};
Thanks,
