// To compile this file use this command:
$ arm-linux-gnueabihf-gcc i2c-gpio-test.c -o i2c-gpio-test

How to use this application:

Use a link to connect these pins:
J34.2 with J34.4
J34.3 with J34.5

The test will change the value of GPIO pins J34.2&3 and reads the level from pins J34.4&5.
This test also can read the status of user button.
