Abstract:
A method for determining a position of a joystick in data communication with a processor and having an initial state, said method comprising steps of:varying said initial state in response to a signal from said processor;returning said joystick to said initial state after a duration of time, with said duration of time being dependent upon said position amongst a plurality of positions;executing a plurality of poll operations of said joystick to sense said returning step, each of which results in a data signal being transferred from said joystick indicating the state of said same, with consecutive poll operations being separated by a predetermined segment of time, defining a first interval;transferring said data signals to said processor, with consecutive data signals operations being separated by a time period, defining a second interval;increasing said second interval to be greater than said first interval; andmeasuring said duration of time by determining a number of data signals received by said processor between said varying step and said returning step wherein increasing step increases said second interval to be the range of 3.75.times.10-7 to 10.00.times.10-7 seconds, inclusive.
