At the nsh, we can turn the outputs on and off with the following::
nsh> gpio -o 1 /dev/gpout0
nsh> gpio -o 1 /dev/gpout1
nsh> gpio -o 1 /dev/gpio0
nsh> gpio -o 1 /dev/gpio1
nsh> gpio -o 0 /dev/gpout0
nsh> gpio -o 0 /dev/gpout1
nsh> gpio -o 0 /dev/gpio0
nsh> gpio -o 0 /dev/gpio1
We can use the interrupt pin to send a signal when the interrupt fires::
nsh> gpio -w 14 /dev/gpint2
nsh> gpio -w 14 /dev/gpio2
The pin is configured as a rising edge interrupt, so after issuing the
above command, connect it to 3.3V.
