I have a BBB running Debian GNU/Linux 7, 3.8.13-bone47 kernel. I.e.
pretty standard.
My raw ADC files are to be found at:-
/sys/devices/ocp.3/44e0d000.tscadc/tiadc/iio:device0/in_voltage0_raw
/sys/devices/ocp.3/44e0d000.tscadc/tiadc/iio:device0/in_voltage1_raw
/sys/devices/ocp.3/44e0d000.tscadc/tiadc/iio:device0/in_voltage2_raw
/sys/devices/ocp.3/44e0d000.tscadc/tiadc/iio:device0/in_voltage3_raw
/sys/devices/ocp.3/44e0d000.tscadc/tiadc/iio:device0/in_voltage4_raw
/sys/devices/ocp.3/44e0d000.tscadc/tiadc/iio:device0/in_voltage5_raw
/sys/devices/ocp.3/44e0d000.tscadc/tiadc/iio:device0/in_voltage6_raw
/sys/devices/ocp.3/44e0d000.tscadc/tiadc/iio:device0/in_voltage7_raw
Currently I use a find() function written in python which walks the
/sys/devices tree to find these files, but it's very slow. If I hard
code the file names how often, if at all, will they need changing?
... and/or is there an easier way to find them, i.e. is there a
configuration file somewhere that tells me where they are (or at least
the non-constant bits of the path)?
