DRV8702-Q1: How to control the direction and speed of motor with PWM ?

Part Number: DRV8702-Q1


Tool/software:

 你好 ,我正在考虑使用DRV8702-Q1 做一个电机控制器的驱动,请问如何控制电机的方向和速度,

在规格书第Page 24 中介绍PWM控制接口,IN1=1 是否意味着可以输入PWM占空比为100% ?而IN1=0 , 则意味 PWM0% ? 比如 IN2 端口输入PWM duty 0%(相当于低电平 0 ),此时 IN1 端口输入PWM duty 0%--100% 变化 ),是否意味着电机速度从0 到最高速度 ?

 

谢谢,
