[arm-allstar] Analog inputs on BBB

[Elliott L]

Hi All,

Does anyone know how to access the analog inputs on the beagle bone black
using the Ham VoIP release with kernel 3.16? I do not see any of the usual
entries in /sys for the analog pins. I do see something for the GPIO pins
in /sys/class/gpio/ which looks functional, but not analog.

I have wired the first analog input pin of the BBB's header to the IF
amplifier in my GE MSTR Exec II receiver, and I am hoping to be able to
report signal levels over the air by reading out the voltage. I remember
some repeaters having this capability "back in the day" using expensive
computerized controllers. Should be a piece of cake with a real computer
available.

I know these ADCs are pretty low quality but I think for low-precision DC
measurements they should be sufficient.

Any help before I start upgrading packages and breaking stuff would be
greatly appreciated ;-) Once I get the script working I will share it here.

Happy New Year all,

--Elliott, W6EL
