怎么让一个拖钓马达跟随操纵杆

我用的是pic16f1937处理器。我的配置是，我有一个操纵杆，在中间测量2.5V，在右边测量4V，在左边测量1V（从左向右摆动3V）。我有一个直径磁化的圆盘磁铁安装在拖动电机的中心轴上。我用的是磁位置传感器集成电路，它有一个从左向右摆动的2V摆幅，它测量3.5伏，电机指向正前，电机指向右90度时为2.5伏，指向左90度时为4.5伏。旋转马达的NG马达。把马达从左转90度转到右转90度需要400步或时钟脉冲。我用adc通过磁定位集成电路找到操纵杆的位置和拖车马达的方向。我想写一个代码，用磁定位芯片将步进电机定时到跟随操纵杆的位置，从而确定步进电机的定时量。我在操纵杆上测量3V摆动（1V到4V）和反向2V摆动（4.5V至2.5V）的测量值。磁定位集成电路的研究从左到右旋转拖曳马达需要400个步骤。我很难理解代码来实现这一点。所有的建议都非常感谢！谢谢

    I'm using the pic16f1937 processor.

My configuration is that I have a joystick that measures 2.5V at middle, 4V at full right and 1V at full left (a 3V swing from left to right).

I have a diametrically magnetized disc magnet mounted in the center shaft of the trolling motor.  I'm using a magnetic position sensor ic that has a 2V swing from left to right with it measuring 3.5 with the motor pointed straight forward, 2.5V when the motor is pointed 90 degrees to the right and 4.5V when pointed 90 degrees to the left.

I have a stepper motor mounted to the shaft of the trolling motor that turns the trolling motor.  It is 400 steps, or clock pulses, to turn the motor from 90 degrees left to 90 degrees right.

I use the adc to find the position of the joystick and the direction of the trolling motor via the magnetic positioning ic.  I want to write code that will clock the stepper motor to follow the joystick using the magnetic positioning chip as to where the motor is pointing and therefore how much to clock the stepper.

I have a 3V swing (1V to 4V) measurement on the joystick and an inverse 2V swing (4.5V to 2.5V) measurement on the magnetic positioning ic.  It takes 400 steps to turn the trolling motor from left to right.

I'm having trouble making sense of the code to do this.  All suggestions are very appreciated!

Thanks
