Anyone know how to access RasPi GPIO without sudo?

johnbeetem
johnbeetem over 11 years ago

I've finally gotten around to playing with RasPi GPIOs, using Gert van Loo and Dom's C code at the RasPi Wiki.  It works fine, except that you have to run the executable as root or use sudo to access /dev/mem.

 

Does anyone here know how to access /dev/mem as a normal user?

    Here is how I did it.

     

    http://www.mobilewill.us/2012/07/raspberry-pi-and-gpio-permissions.html

     

     

    I gave access to a user to run only a script as root by editing the sudoers file. This keeps the security but allows you to access the GPIO.
