Examples

Here is a basic example of the Level component. The example collects the max, min and average readings from the buffer and displays them on the LCD display.

Level

The values in the buffer are defined using the InputADC component.

Min: Minimum (smallest) value read from the buffer.

Max: Maximum (largest) value read from the buffer.

Average: Rolling average calculated from the values inside the buffer.

	Properties
	Connect To
DSP component with output buffer to collect our data from.
	Decay on Peak/Trough
Yes - The Peak and Trough value will only be maintained for the decay number of buffers. No - The record Peak and Trough values will be maintained until reset.
	Decay
Configures how many buffers or values to allow a record to persist
