Design and Research of Freescale Smart Car Keyboard in Mechanical Manufacturing Engineering
Keyword(s):
The keyboard is made up of a number of key switch matrix. It is the simplest digital input device of MCU (micro control unit). The operator inputs data or commands through the keyboard and realizes the communication between people and machine. In the process of Freescale intelligent car competition, many operations are completed by keyboard such as speed adjustment, mode switch, reference frame changing and so on. In order to improve the adaptive ability of intelligent car, the keyboard plays an important role. So the design of the keyboard also becomes a very critical process in smart car design.
