Level component
Allows for detection and collection of peaks, troughs and averages.
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.
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.
