To remove the configuration of the pin, use:

$ gpio unexport 1

To remove all configurations:

$ gpio unexportall

Feel free to use the gpio program to configure other pins as input or output (PWM is only for special function pins like GPIO18(WiringPi 1), other PWM pins are occupied by the 3.5mm audio connector.

  to your compile line(s) To use the Gertboard, MaxDetect, etc.

  code (the devLib), you need to also add:

    -lwiringPiDev

  to your compile line(s).
