Tutorials, examples on using 40-Pin Header (Solved)

Hi
Now I am more comfortable with CUDA, it’s time to input/output data from the real world.
I am looking for the tutorials or examples on using GPIO and other features on the 40-Pin Header.
Anyone ?

Thanks

hello sato5312,

please download the L4T documentation,
you could also check [Tegra Linux Driver Package TX2 Adaptation Guide]-> [GPIO changes] chapter for how to get the gpio number examples.
thanks
