JOYSTICK INTERFACES AND METHODS OF PROVIDING POSITION INFORMATION OF A JOYSTICK

摘要

This invention provides joystick interfaces and methods of providing position information of a joystick. According to one aspect, the invention provides a joystick interface for use with a joystick, the joystick interface being configured to selectively operate in one of a digital mode and an analog mode, the joystick interface including an interconnect adapted to couple with a host system; a timing circuit adapted to couple with a joystick having a lever and configured to output a timing signal having a timing characteristic which is dependent upon the position of the joystick lever; and logic circuitry coupled with the interconnect and the timing circuit and configured to initiate a timing operation within the timing circuit to generate the timing signal and output an indication signal responsive to the timing signal during operation in an analog mode of operation, the logic circuitry being further configured to generate and output a digital value to the interconnect responsive to the timing signal and during operation in a digital mode.
