Revision history [back]

There is a library called wiringPi which implements more features than the BCM library and is a lot easier to use. I started writing a ROS wrapper using the bosch_drivers architecture. If you only want to access the GPIOs, the code should work out of the box, there is even a gpio test program. Just follow the instructions in then README
