| Abstract: | This paper introduces the design thoughts, the working principle and the realization of a kind of digital colorized LCD automotive instrument based on ARM. By using high-performance microcontroller AT91SAM9263, combined with embedded operating system μC/OS-Ⅱ and graphical user interface μC/GUI, the system constructs the unified information platform of the automotive working conditions, provided such functions as the real-time data communication with CAN bus and could display all vehicle operating parameters with alarm function. This expansible system will be a direction in the digitized and intelligentized progress of the automotive instrument. |
