Detailed Description

Helper class to detect falling edge of any changing value in C++ code

Constructor

FallingEdgeDetector::FallingEdgeDetector(T initialValue)

• Parameter initialValue specifies the start value to start detecting edges from

Methods

bool FallingEdgeDetector::detect(T newValue, T threshold)

• detects if the newValue represents a falling edge of the value and stores the newValue as last known value for possible next detect. Parameter threshold specifies the threshold (absolute, positive) value that will be considered as the minimum change for the edge to be detected. For boolean values the threshold has no meaning.
• Returns true if there was a falling edge compared with last known value.
