Abstract
A method for determining a position of a joystick in data communication with a processor and having an initial state that includes steps of varying the initial state in response to a signal from the processor; returning the joystick to the initial state after a duration of time, with the duration of time being dependent upon the position amongst a plurality of positions. A plurality of poll operations of the joystick are executed to sense the returning step. Each of the polling operations results in a data signal being transferred from the joystick indicating the state of the same, with consecutive poll operations being separated by a predetermined segment of time, defining a first interval and consecutive data signals operations being separated by a time period, defining a second interval. The second interval is increased to be greater than the first interval, the duration of time is measured by determining a number of data signals received by the processor between the varying step and the returning step. Thereafter, the spatial position of the joystick is determined.
