问在Python中使用asammdf解码CAN帧

EN

from asammdf import MDF
import cantools

filename = "~/mdf_dbc_play/tmp.dbc"
db = cantools.database.load_file(filename)

msg_bytes = [0,0,0xff,0x01,0x02,0x03,0x04,0x05]
# Temporary bogus timestamp
timestamps = [0.1]

# Use cantools to decode the raw bytes
msg = db.get_message_by_name("EEC1")
unpacked_signals = msg.decode(msg_bytes)

# Using version 3.10 just in case we have some versioning issues with old tooling.

with asammdf.MDF(version='3.10') as mdf:
    # I assume there's some way of getting the actual value we care about from an unpacked message.
    samples = unpacked_signals.get_values()

    sig = asammdf.Signal(name="EEC1", samples=samples, timestamps=timestamps)
    mdf.append(sig)
    mdf.save("~/mdf_dbc_play/output.mdf")
