Abstract
Providing collision avoidance protection to controllers sharing the same sensor. Each of a pair of asynchronous controllers changes the period of a sync pulse transmitted to the other controller to indicate to the other controller it is synchronized. When one of the controllers begins reading data from the shared sensor, the other controller waits to receive another sync pulse for indicating when the controller is finished reading data from the shared sensor. Thus, the asynchronous controllers avoid accessing the same sensor at the same time.
