X12.017嵌块驱动器在汽车仪表中的应用

Application of the M-S Quad Driver X12.017 in the Car Dashboard

以微处理器为核心,应用传感器将水温和燃油液面位置转换成相应的电阻值,通过恒流源变换成相对应的电压模拟信号,经模数转换器变换为数字信号,应用相关算法,进行线性化处理。通过X12.017嵌块驱动器驱动步进电机带动指针转动,指示出实测的水温和燃油液面值。

With the microprocessor for the core,the temperature of water and position of gasoline can be converted corresponding digital signals by using sensors,current source and analog to digital converter,the M-S Quad Driver X12.017 converts a pulse train f （scx） into a current level sequence sent to the motor coils. This sequence is used to produce the microstepping movement of the motor. It indicates the real value of measure.
