|Free Buzz tool facilitates easy connectivity checking. To check if a connection is present the driver is selected from the list on the left and drag and dropped in the left Buzz field. Likewise the sense pin is selected and placed in the right Buzz field. When the Buzz test is executed a sound indicates whether a connection was found or not. The result is also indicated graphically by the color of the field between the drive and sense pin. Other measurements in the Buzz tool allow for checking the activity of a pin (Watch window at the top), or measure the response on input pins when driving various driver pins (Measure window in lower part).
