【摘要】 介绍一种AVR单片机串行通讯在汽车油耗测量中的应用方法.此方法能够将测量结果通过软件控制以数字信号的方式传送给主控单片机,减小了远距离传输的信号衰减和外界干扰,十分适合用于汽车油耗的测量.配合标准容积的油箱使用,测量精度达到了0.1%～0.5%.更多还原

【Abstract】 This paper introduces a method of AVR MCU serial communication in the applicaton of car oil measuring, by which the measuring data can be transfered into the main MCU by software control. It’s suitable for cars because the signal attenuation and electromagnetic interference are reduced. This meter reaches an accuracy of 0.1~0.5% accompanied with a standard-volume oil tank.更多还原
