请问pyb中can.send函数怎么发送8个字节？发送了一个列表提示错误。

import time
from pyb import Pin, Timer
from pyb import CAN
can2 = CAN(2,CAN.NORMAL,extframe=False,prescaler=9,sjw=1,bs1=8,bs2=3)
can2.setfilter(0,CAN.LIST16,0,(0,1,123,124))
ID=0x111
MSG=123
Data=[1,2,3,4,5,6,7,8]

def tick(timer):            # we will receive the timer object when being called
    print("Timer callback")

tim = Timer(4, freq=1)      # create a timer object using timer 4 - trigger at 1Hz
tim.callback(tick)          # set the callback to our tick function

while(True):
    time.sleep(1000)
    print("wait")

    can2.send(MSG,ID,timeout=3000)
    can2.send(Data,ID,timeout=3000)

非常感谢！能通过，但是我想知道原因，为什么需要用bytes（）来将数组转换才能传入数组？

@z1sk 数组不是字节。你要考虑大小端的问题。
