Re: [fpc-pascal] Access GPIO pins on RPi2 without root?

OK, I have now subscribed to the fpc-other list. Hopefully I can ask "stupid" fpc usage questuions there... Best Regards, Bo Berglund -Original Message- You just mentioned that you don't like to subscribe to mailing lists because you already receive many mails. By posting mails on

How can one control the GPIO outputs on a Raspberry Pi2 without needing the program to run as root? I am using Raspbian Wheezy and I need to add two relays controls to my program. The pages I have found with google are for the original Pi so the connector referenced is the wrong size and it is
