There's another GPIO mode which is INPUT. It takes the digital signal input
from the pin and interprets it into 1 and 0. This example will continuously
print out the value received from P10 on the board. You can short 3V3 and
P10 to observe the change in values
Finally, an interrupt service routine can be installed to the pin and invoked
when the values of the input pin GPIO#2 has changed. Call isr API with the
trigger type you want to register and the function to be called. Note that the
function runs in a different thread.
