I am NOT running my RPi2B as any other user than pi and it works just fine to access the GPIO pins. Both FPC and Lazarus run just fine as pi user. The trick is to make sure that pi belongs to the proper groups dealing with the hardware. You can check this using the command: cat /etc/group | grep pi It will list the groups pi belongs to and you will find out if there are missing groups here. This is what my Pi says: pi@rpi2-jessie2:~/dev $ cat /etc/group | grep pi adm:x:4:pi dialout:x:20:pi cdrom:x:24:pi sudo:x:27:pi audio:x:29:pi video:x:44:pi plugdev:x:46:pi games:x:60:pi users:x:100:pi input:x:101:pi netdev:x:108:pi spi:x:999:pi i2c:x:998:pi gpio:x:997:pi <== This for GPIO I never use the NOOBS disk, I always create the start image from the offiocial Raspbian Jessie image, currently I am on the Nov 2015 release. And the groups above were set from the start on that distro. -- Bo Berglund Developer in Sweden -- _______________________________________________ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
