I am retrofitting a DC motor powered electronic height gauge.
BBB control will allow the system to remain fully self contained.
Here is what I see as requirements:
Able to read quadrature signal from 20 micron scale at sufficient
speed to be usable (tbd).
Read a analog signal from the lvdt or strain gauge touch probe for
gauge force set point. I already have suitable lvdt's but suspect
a strain gauge may be easier to implement.
Servo drive the DC motor that positions the probe carriage.
Please point me in the right direction to get started using BBB.
Any thoughts on PID control with dual feedback (linear scale as
well as touch probe).
I see there is now A BeagleBone Blue Servo version. Searches here
have been no real help.
Can we put Machinekit on this new BBBlue servo edition and control its
onboard hardware?
Thanks for the info.

Hobby Servos and machine drive servos are two different things.
