Hi guys,
I want to interface a magnetic scale position sensor with a BeagleBone
Black (an ARM development platform).
While I was reading this following article :
http://bwgz57.wordpress.com/2012/04/11/beaglebone-with-a-rotary-encoder/
I discovered that linux has built-in support for rotary encoders
connected via GPIO.
The magnetic scale position sensor can be considered like a rotary
encoder so I would use the rotary_encoder platform device driver.
I've read the code example at the end of this document :
https://www.kernel.org/doc/Documentation/input/rotary-encoder.txt
But I don't know how to access to the "pos" value of the rotary encoder.
Do you have some code example of use of this driver ? Or anything that
can be helpful for me.
Thanks,
Regards,
Loïc
