I am trying to use HiPi and FHEM (http://fhem.de/fhem.html, perl-based). I keep getting error messages when the BCM2835 library attempts to access /dev/mem. This is what I am doing:
1. sudo perl fhem.pl
2. call from FHEM: HiPi::BCM2835::bcm2835_init()
At this point, an error "bcm2835_init: Unable to open /dev/mem: operation not permitted" is thrown.
I use 2013-09-25 wheezy and am stuck here.
Any hint appreciated!
