| Abstract: | This paper introduces the design of a new generation combined meters, which is based on ST72F561, an 8-bit microprocessor from ST Company. In the meter, the mileage is displayed on LCD display, the rotation speed, vehicle speed, water temperature and fuel level are displayed on needle meters driven by stepper motors. The meters also have the following functions such as protecting important data when power down ; alarms for over speed, low fuel and high water temperature; various signal indicators and CAN-bus communication capability. Experimental results prove that the proposed design conforms to the national standard and has high display precision. |
