基于python-can的blf格式日志转csv格式脚本

import sys
import binascii
import can
import time
from datetime import datetime

# 时间戳转换为真实时间
def timestamp_convert_realtime(ts):
    return str(datetime.fromtimestamp(float(ts)))


def main():
    """The transcoder"""
    with open("blf2csv.csv", mode="a+") as f:
        f.write("timestamp" + 23 * " " + "id      dlc            Data\n")
        
        # 读取文件里的内容，写入新的文件
        with can.LogReader(sys.argv[1]) as reader:
            for msg in reader:
                row = '     '.join([
                    timestamp_convert_realtime(repr(msg.timestamp)),
                    hex(msg.arbitration_id),
                    str(msg.dlc),
                    (binascii.hexlify(msg.data, " ")).decode("utf-8")
                ])
                f.write(row + "\n")


if __name__ == "__main__":
    start_time = time.time()
    main()
    end_time = time.time()
    print(f"用时{int(end_time - start_time)}s")

以上只是一种简单转换思路，通过命令行方式进行执行，仅供参考。
