# Motor Shield PWM Example # # This example shows off how to control the motor shield on your # OpenMV Cam. The motor shield is controlled by using the PYB module # which lets you do PWM to control the speed and set digital I/O pin # states. The motor shield needs 6 I/O pins for both motors. import pyb #from pyb import Pin, Timer tim = pyb.Timer(4, freq=50) chA = tim.channel(1, pyb.Timer.PWM, pin=pyb.Pin("P7"))# chB = tim.channel(2, pyb.Timer.PWM, pin=pyb.Pin("P8")) times = 500 while (times >1): chA.pulse_width_percent(40)# chB.pulse_width_percent(30)# times = times - 1 pyb.delay(10) chA.pulse_width_percent(0)#向前 chB.pulse_width_percent(0)#
