gpioIrq

Example of using sysfs for edge detection interrupts on the Omega's GPIOs.

Compilation

In order to run this program on the Omega2, it must first be compiled for the MIPS architecture.

The available options:

Both methods will work, it is up to the user.

Usage

The executable is meant to be run with an argument that identifies the GPIO pin which is to be monitored for a change in the voltage level (an edge):

./gpioIrq <GPIO-Number>

To test this program, run it and try using a jumper wire to connect the selected GPIO to GND and then 3.3V. Monitor the output of the program and observe what happens.
