To run the Hipi Control GUI
The GPIO Pad services provide access to control of the GPIO pins on the Raspberry Pi. You can toggle the pin modes between input and output. For output pins you can set the level high or low. For input pins you can set options for edge detection or interrupts. You may also apply or remove pull up and pull down resisitors to the pins. Note that it is not possible to retrieve the current state of pull up / down resistors so it is up to you to remember the settings you have applied and revert your Pi to its defautl state as necessary.
