如何使用 python 将 CAN 的.blf 数据转换为.asc

Question

I have a.blf file, I have to convert that to a.asc file so that my ASCREADER is able to read the data.

from can.io.blf import BLFReader
blf_file = "/home/ranjeet/Downloads/CAN/BLF_Files/input.blf"
with BLFReader(blf_file) as can_log:
    for msg in can_log:
        print(msg)

I've tried this so far. Able to read BLF File, need to write data as per.asc file

Answer 1

Very similar to my other answer you should read your blf file in binary mode then write the messages in the asc one:

import can

with open(blf_file, 'rb') as f_in:
    log_in = can.io.BLFReader(f_in)

    with open("file_out.asc", 'w') as f_out:
        log_out = can.io.ASCWriter(f_out)
        for msg in log_in:
            log_out.on_message_received(msg)
        log_out.stop()
