This example creates a single encoder instance that is updated by
|
|
running the service method directly in the main program loop. This
|
|
must be called frequently enough to avoid missing any pin changes. That
|
|
means several hundred times a second in many cases. If a change is detected
|
|
in the main loop, the current count is sent to the serial port.
|
|
|
|
You can add a delay into the loop in this eample to see just how often you
|
|
need to call the service method and still get reliable counts.
