这个pwm里面Timer.channel(channel)的channel参数具体取值是多少，范围是多少

[5zgw]

我用不同的Timer

p1 = Pin("P1", Pin.OUT_PP)
p2 = Pin("P2", Pin.OUT_PP)
p3 = Pin("P3", Pin.OUT_PP)
p4 = Pin("P4", Pin.OUT_PP)

tim1 = Timer(1, freq=1000)
tim2 = Timer(2, freq=1000)
ch1 = tim1.channel(2, Timer.PWM_INVERTED, pin=p1)
ch2 = tim1.channel(3, Timer.PWM_INVERTED, pin=p2)
ch3 = tim2.channel(2, Timer.PWM_INVERTED, pin=p3)
ch4 = tim2.channel(3, Timer.PWM_INVERTED, pin=p4)

这里加了ch3和ch4就运行不了
