Research and Implementation of Message Queue on Key Event Processing

Abstract

As electronic technology products continue to expand the control panel buttons, there are hundreds of buttons, and different types of buttons. In this paper, the advantages and functions of message queue in the processing of key events are analyzed in detail. Proposed bond between the control board and the control board to pass key information through SPI communication method, and implemented in Free ROTS(embedded operating systems) use a variety of different message queue management of key events, and in response to key events. The conclusion is that the main control board chip can use software to classify the key events by message queue.
