openmv连接arduino运行不了

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('P5', Pin.OUT_PP)
ain2 =  Pin('P6', Pin.OUT_PP)
bin1 =  Pin('P9', Pin.OUT_PP)
bin2 =  Pin('P4', 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)

def run(left_speed, right_speed):
    if inverse_left==True:
        left_speed=(-left_speed)
    if inverse_right==True:
        right_speed=(-right_speed)

    if left_speed < 0:
        ain1.low()
        ain2.high()
    else:
        ain1.high()
        ain2.low()
    ch1.pulse_width_percent(int(abs(left_speed)))

    if right_speed < 0:
        bin1.low()
        bin2.high()
    else:
        bin1.high()
        bin2.low()
    ch2.pulse_width_percent(int(abs(right_speed)))

上面是openmv代码下面是arduino代码
void setup()
{
pinMode( 5 , OUTPUT );//低电平正转
pinMode( 6 , OUTPUT );//高电平反转
pinMode( 9 , OUTPUT );//高电平正转
pinMode( 4 , OUTPUT );//低电平正转
}

void loop()
{
analogWrite( 5 , 0 );
analogWrite(6,255);
analogWrite( 9 , 255 );
analogWrite(4,0);
}
然后在openmvIDE里运行脚本摄像头闪彩灯运行不了这是为什么

你的OpenMV的代码，只定义了函数，没有运行函数。

运行函数咋弄，求大神教教

ch2.pulse_width_percent(0)

def run(left_speed, right_speed):
    if inverse_left==True:
        left_speed=(-left_speed)
    if inverse_right==True:
        right_speed=(-right_speed)

    if left_speed < 0:
        ain1.low()
        ain2.high()
    else:
        ain1.high()
        ain2.low()
    ch1.pulse_width_percent(int(abs(left_speed)))

    if right_speed < 0:
        bin1.low()
        bin2.high()
    else:
        bin1.high()
        bin2.low()
    ch2.pulse_width_percent(int(abs(right_speed)))

run(100,100)
while True:
    pass

但是这个代码和Arudino并没有什么关系。。。

我用的openmv官网追小车的代码怎么能连接上arduino，然后控制他
