Knobs & Selectors
The Knobs & Selectors library contains two dial blocks that you can control
using the mouse:
•The Generic Knob block assumes values in a continuum by default. You can
also configure it to assume discrete values along a linear scale. For common
customizations specific to this block, see “Customizing the Generic Knob
Block” on page 3-9.
•The Frequency Selector block assumes only values in a discrete set. The
discrete set can be labeled with alphanumeric captions of your choice, but the
block’s output values are nonnegative integers. For common customizations
specific to this block, see these sections:
- “Customizing the Frequency Selector Block” on page 3-10
- “Creating a New Set of Selections” on page 3-11
- “Changing Output Values” on page 3-13
