A keypad protocol is provided as part of mobile device system software to serve as a standard interface between application software and keypads and other user-interfaces. The keypad protocol can provide a common set of interfaces and APIs to facilitate development of applications that are compatible with a wide variety of keypads, including keypads that may be developed after applications are fielded. Similarly the keypad protocol can provide a common set of data structures and interfaces for accepting key press event notifications from and providing configuration information to keypads made by a variety of manufacturers. The keypad protocol can inform applications of the keypads activated and connected to the mobile device and useable by the application. Applications can inform the keypad protocol of a keypad selected for use as well as configure how the selected keypad should interface with the application. |
