Looking up for GPIO library documentation

Yves McDonald

Other Parts Discussed in Thread: AM3517

Hello,

I am currently working on an embedded system featuring the AM3517 Sitara processor. I'm developping the software device driver for it. I'd like to get started with the GPIO library for Linux (kernel 2.6.32/ti-SDK/Eclipse IDE). I searched TI website as well as the Web in general, but could not find any documentation for it.

Is there a 'Start Here' link for GPIO library to documentation and code samples?

 

Thanks!

    You could check the documentation within the kernel itself at

    Documentation/gpio.txt

    Later kernels have edge detection/interrupt functionality. User space examples are common on the web. Search for "/sys/class//gpio".
