如题，如何应对no module named 'pyb'的报错？是只能移植代码还是有别的方法可以直接跑openmv的程序呢？部分例程如下
- from pyb import Pin, Timer
- inverse_left=False #change it to True to inverse left wheel
- inverse_right=False #change it to True to inverse right wheel
-
- ain1 = Pin('P0', Pin.OUT_PP)
- ain2 = Pin('P1', Pin.OUT_PP)
- bin1 = Pin('P2', Pin.OUT_PP)
- bin2 = Pin('P3', Pin.OUT_PP)
- ain1.low()
- ain2.low()
- bin1.low()
- bin2.low()
-
- pwma = Pin('P7')
- pwmb = Pin('P8')
- tim = Timer(4, freq=1000)
- ch1 = tim.channel(1, Timer.PWM, pin=pwma)
- ch2 = tim.channel(2, Timer.PWM, pin=pwmb)
- ch1.pulse_width_percent(0)
- ch2.pulse_width_percent(0)
