Timers Tab

Overview

The Timers Tab provides configuration of various types of timers.

Timer Types

Performance Timer

Performance Timers provide a convenient way to configure timers that measure the time elapsed over a range, typically distances or speeds. For example, time over 1km or 0…60mph or 60…100mph etc.

Use the Quick Setup button to easily configure distance or speed range timers.

Distance based Performance Timers will typically use a speed input and numerically integrate the speed to give distance for the stop condition limit. Integration is performed with respect to time; speed channels should have units of d/s, where d is a distance unit (e.g. km/s or mi/s) - integration will then result in a value with units d.

Integration uses the trapezoidal rule and the stop time is interpolated between the samples between which the stop condition became true.

Performance Timer Events

Stopwatch

A timer that may be started / stopped / reset by the event system. Stopwatch timers are reset to 0 and count up from there.

Stopwatch Events

Count Down

Count Down timers start at a editable starting time, Initial Value, and count down from there until 0 is reached.

As with Stopwatch timers, Count Down timers are controlled by the events system.

The starting time may be adjusted by increase / decrease events. This can be useful for implementing a count down timer configuration page on the display. If hardware buttons are available then when on the timer configuration page, the buttons can be routed to the timer using the events system. See also Events Tab .
