Hi, thank you for your code! it is really helpful to me. However, when I used MRAA library in ROS to read/write GPIO, I found that MRAA lib needed "root" permission. As I cannot directly use the command "sudo roslaunch ..." in the terminal, I am curious whether there is a way to solve its problem other than just using "sudo su"?
