Detailed Description

The ToggleOperator toggles output value on input rising and/or falling edge(s). If configured edge is detected, output is changed to opposite value (from true to false or false to true correspondingly).

Properties

NB! Input values can be routed from signals of another type. Then other type value is converted to boolean using C++ logic - zero values are converted to false and other values are converted to true.

When operator is used inside a signal its default input is automatically tied to signal's InternalValue or previous operator's output. Its default output is automatically tied to next operator's input or to signal's Value. See also CDP Operator Usage In CDP Signals.

Example

Below is example plot with input boolean signal (cyan) with ToggleOperator(Edge=RisingEdge) applied (orange).

Actual Processing Code of the ToggleOperator

unsigned int ToggleOperator::Process()
{
  if ((d->RisingEdgeToBeDetected() && d->RisingEdgeInInput((bool)m_input)) ||
      (d->FallingEdgeToBeDetected() && d->FallingEdgeInInput((bool)m_input))) {
    m_output = !d->lastOutput;
    d->lastOutput = (bool)m_output;
  } else
    m_output = d->lastOutput;
  d->lastInput = (bool)m_input;
  return STATUS_OK;
}
