DRV8834 来控制电机,该控制哪些引脚

Other Parts Discussed in Thread: DRV8834

BPHASE:  direction

ANEBL: logic down enables all outputs

BNEBL:   rising edge moves to next step

M0: logic high set Aout1 high Aout2 low.control along with M1  

M1: determines the state of the outputs when xENBL = 0. Control along with M0.

SLEEP:   logic low to enter low-power sleep mode and reset all internal logic.

方向用BPHASE 来控制,另外一些说的很多,有点混乱,以至于我不知道该将哪个引脚复用为定时器,并配置成PWM模式。
