Python 使用can模块（记录稿）_pip install can

直接安装：pip install python-can

如果报这个错

更新一下pip

pip3 install --upgrade pip

或者是 pip install --upgrade pip

再安装wrapt

pip install wrapt

再 pip install python-can 就可以了  

测试：

demo.py

import os
import can
import time
 
 
bus = can.Bus(interface='socketcan',
              channel='can0')
can.rc['bitrate'] = 10000
 
'''
# send a message
message = can.Message(arbitration_id=123, is_extended_id=True,
                      data=[0x11, 0x22, 0x33])
bus.send(message, timeout=0.2)
'''
 
## received messages
 
for msg in bus:
 
    timeArray = time.localtime(msg.timestamp)
    otherStyleTime = time.strftime("%Y-%m-%d %H:%M:%S", timeArray)
 
    print(f"Time: {otherStyleTime}  Channel: {msg.channel}   DLC={msg.dlc}    Data-ID: {msg.arbitration_id:X}")
    i = 0
    for data in msg.data:
        s = str(hex(msg.data[i]))
        i+=1
        print(s[2:].upper(),end=' ')
    print("\n")
    #print(msg)
