Subject: Rotary encoder platform device driver code examples
Date: Wed, 21 Aug 2013 22:50:16 +0200	[thread overview]
Message-ID: <52152808.1000608@rs2i.net> (raw)

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
