Timer Widget

Timer widgets are special widgets that do nothing except being called at a regular basis. Their expression is evaluated (if the active expression is not zero), the result is discarded. But you can set variables in this expression, and call functions that do something useful (e.g. setting contrast or backlight).

Here's the definition of a timer widget:

Widget <name> {
    class      'Timer'
    expression <string>
    active     <number>
    update     <number>
}

---

Parameters:

expression	main expression
active	timer is active if != 0
update	update interval (msec)

Note that the update and active expressions are evaluated every time the timer is called, sou you can modify the values at runtime.
