Counters and Edge Detectors

In the integrated development environment CannyLab the following types of counters and detectors:

Symbol	Function block name
	Counter: at a zero value at the “Reset” input: on each leading edge at the “Increment” input, adds one to the output value, and on each rising edge at the “Decrement” input, subtracts one from the output value
	Rising edge detector: signal source of minimum duration (one pass of the diagram), synchronized by the leading edge
	Falling edge detector: signal source of minimum duration, synchronized with a falling edge
