发明名称 Method to detect and recover from stuck keys on an electronic device keyboard
摘要 A method of detecting and recovering from stuck keys on an electronic device keyboard comprises receiving one or more messages by a processor based upon a predetermined periodic scan rate and each message corresponding to a pressed key, determining one of the pressed keys is a stuck key based upon the received one or more messages corresponding to a pressed key, sending a mock key-up message from the processor to a keyboard controller in response to the determined stuck key, operating the keyboard controller at a changed scan rate in response to the mock key-up message, detecting the electronic device keyboard is in a released key state by the processor; and operating the keyboard controller at the predetermined periodic scan rate in response to the detected released key state. The processor can include two components, such as a keyboard processor and a keyboard controller.
