Flip-Flop Component

The Flip-Flop Component converts a trigger type input to a Boolean type output.

Use Cases

Use Case 1 - If you want a physical momentary button to act like a toggle button.

  1. Hard wire the button to a Digital Input pin on the GPIO connector on the Core or I/O Frame.
  2. In Q-SYS Designer, wire the Digital Input pin to the Toggle Input Control Pin of a Flip-Flop component.
  3. When the design is running, press the momentary button, a trigger is sent through the GPIO to the Toggle Input Control Pin on the Flip-Flop. The Flip-Flop changes State.
  4. Every time the button is pressed, the Flip-Flop changes State.

Use Case 2 - If you want two physical momentary buttons, one to turn something on, the other to turn it off.

  1. Hard wire the buttons to two Digital Input pins on the GPIO connector on the Core or I/O Frame.
  2. In Q-SYS Designer, wire one Digital Input pin to the Set Input Control Pin, wire the other to the Reset Input Control Pin of a Flip-Flop component.
  3. When the design is running, press the ON (or "Set") momentary button, a trigger is sent through the GPIO to the Set Control Pin on the Flip-Flop. Depending on the Flip-Flop's current State, the Flip-Flop may change State.
  4. Press the OFF (or "Reset") button, after pressing the ON button, the Flip-Flop changes State.

Controls

When a trigger type control is wired to any one of the Flip-flop's trigger inputs, every time the trigger type control is triggered, the Flip-flop responds. When a Boolean control is wired to a Flip-flop trigger input, the Flip-flop responds when the Boolean control changes to true.

Control

Function

Default/Range

Set

A trigger that sets the State to True

N/A

Reset

A trigger that sets the State to False

N/A

Toggle

A trigger that toggles State

N/A

State

Represents the state of the flip-flop. This control can be stored in a snapshot. The value of the State button is restored on startup.

Although it is a toggle button, it isn't normally use it as such.

True/False

Out

Read-only LED. The value of State.

N/A

Not Out

Read-only LED. The complementary value of State.

N/A
