更新固件以后官网的追小球代码报错了

就像这样，一识别到小球就报这个错误

官网追小车实例的代码
car.py

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)

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(abs(left_speed))

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

更新了代码，刷新一下网页，不会报错了。

@kidswong999 把后面这一串代码加在之前的代码后面是吗
