说明：  比例液压阀智能驱动器主控制程序,通过可调电位器获取电流值,通过PWM方式产生10位分辨率的可调占空比波形以驱动场效应管产生控制阀体的电流,通过取样电阻获取输出电流值 , 根据反馈电流调整输出波形以稳定输出电流
(Proportional hydraulic valves smart drive master control program, to get the current value adjustable via potentiometer, adjustable duty cycle of the waveform generated by a 10-bit resolution PWM mode to drive the control valve FET current generated by the sampling resistor to get output current value, based on feedback from current adjustment of the output waveform to stabilize output current )
