exampleGPIApp.cpp describes a simple usage case using a tactile button and LED as input and output.
To add more GPIO pins, modify jetsonGPIO.h and add pin numbers you want.
- Example: setup and initialize GPIO388 (Pin37) as output pin on TX2:
/* To initialize */
jetsonTX2GPIONumber LEDControlPin = gpio388;
gpioExport(LEDControlPin);
gpioSetDirection(LEDControlPin,outputPin);
/* To control pin high or low */
gpioSetValue(LEDControlPin, on); //Pull high
gpioSetValue(LEDControlPin, off); //Pull low
That's it, very easy. If you like to use C/C++ to control GPIO Pin, just include "jetsonGPIO.h" in the cpp file.
