-Uncomment the call `test_timer()` in `tests/test_gpio_timer.c` and re-run the test program to verify these tests succeed. Consider what additional tests are needed for the timer module (there may not be much; it is a pretty simple module). Once both modules are passing all of your tests, you're ready to tackle the rest of the clock application.
