Selector

The Selector component makes it easy to switch between a number of configured values to send to a downstream component. Configure a group of control buttons and assign a value or text string to send when a button is pushed on. One button from the group can be active at a time.

  1. Drag the Selector component into your schematic.
  2. Select the component to configure how many selection controls you want. See Properties.
  3. Connect the Selector component's Value control pin to the input control pin of another component.
  4. Press F5 to save your design to the Core and run it. (Or, press F6 to emulate your design.)
  5. Configure the Label and Value for each selection (Sel) button. See Controls.
  6. Click a selection button (or, use the Selection combo box to select an assigned Label) to enable the selected control and send its assigned value to the connected component.

Selection Count

Specify the number of control buttons.

Default = 4

Range = 2 to 64

Function

Default / Range

Label

Specify a text label for the Selection number.

N/A

Value

Specify a text string to send to a connected component when the control button is enabled.

Note: The Value you specify must be compatible with the downstream component's control pin. The output does not auto-convert the string. For example, if the downstream component is expecting an integer, you must first send the string though an integer control which can convert the string to an integer.

N/A

Sel

Click a button to turn on a Selection. (Or, use the combo box to select an assigned Label.)

In this example, the Selector component is configured to set the gain value in the Gain component. The user can easily switch between the set gain values by either pressing a Selection button or selecting a label from the combo box.
