====FirstRun====

The **FirstRun** function is part of the [[Trigger]] class. 

It returns **True** if this is the first time the trigger has been executed.

This is primarily used when you're triggering on both types of [[edge modes|edge]] (ie. the function is being called both when the condition becomes //true// and the condition becomes //false//).

When triggering on both the rising and falling edge, the [[trigger function|trigger function]] will be run when the system first starts up.

In certain cases, you might not want to generate any information on this first event.
