## Timer Functionality
It's possible to start timers and read values for time-specific events - here's an example:
```c
static uint16_t key_timer;
key_timer = timer_read();
if (timer_elapsed(key_timer) < 100) {
// do something if less than 100ms have passed
} else {
// do something if 100ms or more have passed
}
```
It's best to declare the `static uint16_t key_timer;` at the top of the file, outside of any code blocks you're using it in.
