Hello, im currently working on something in the linux system of the cc100 and need to control the Digital Output of the Controller. I have looked online and read about there being a way in /sys/class/gpio. Though i have tried everything and i couldnt get it to output a high on DIO1.  
Can anyone help me out here?
