msg.channel —— channel,取决于录制blf时的channel mapping msg.timestamp —— 录制blf时记录的本条数据时间戳 msg.arbitration_id —— can id,或者叫frame id msg.data—— bytearray格式的raw data raw data如果直接打印的话,默认是按bytearray格式打印的。比如,我们可以筛选出channel=2,id=0x51的数据帧,...

pipinstall-e. 4.找到安装的python-can包,找到vector文件夹,修改vxlapi.py 140行 #CAN FD configuration structureclassXLcanFdConf(ctypes.Structure): _fields_= [('arbitrationBitRate', ctypes.c_uint), ('sjwAbr', ctypes.c_uint), ('tseg1Abr', ctypes.c_uint), ('tseg2Abr', ctypes.c_uint), ...
format(channel)) except can.CanError: print("Message NOT sent") 5. 编写Python代码接收CAN消息 接收CAN消息通常涉及在一个循环中监听总线: python try: while True: message = bus.recv(1.0) # 等待接收消息,超时时间为1秒 if message is not None: print("Message received on {}: {}".format(...
1)socketcan 对应的channel 为:vcan0 SocketCAN 2)ixxat 对应的channel为:0 IXXAT Virtual CAN Interface 3)pcan 对应的channel为PCAN_USBBUS1 PCAN Basic API 4)vector 对应的channel为0,需要额外增加一个app_name 为CANalyzer Vector 5)。。。python-can库基于PCAN-USB使用方法 ...
Python: AttributeError:'list‘对象没有属性'channel’ 、、 我试图使用bus.send_periodic发送100 of的多条消息。然而,当我运行下面的代码时,我得到了错误:AttributeError:'list‘object在第50行中没有属性'channel':Task= bus.send_periodic(messages,0.1)import timeimport cantools bus = <e ...
为什么只能初始化一次特定的PCAN Channel? 、、 在这里使用python-can库。下面是打印can消息的简单代码: from can.interface import Bus bus = Bus(bustype='pcan', channel='PCAN_USBBUS1', bitratecan.interfaces.pcan.pcan.PcanError: A PCAN Channel has not been initialized yet or the initializati...
bus = can.interface.Bus(bustype='neovi', channel='1', bitrate=500000) 如果没有任何异常抛出,那么证明一切正常,但是因为要跟硬件交互,python-can需要调用dll或驱动(一般是c/c++实现),出现异常也是挺常见的,最常见到的就是: ics.RuntimeError: Error: find_devices(): Failed to open library: 'icsneo40...
