I have an A2L file that contains a list of variables and their corresponding 'ECU Addresses.' For example:
https://github.com/christoph2/pyA2L/blob/master/examples/example-a2l-file.a2l.
Now, I need to use CAN XCP to read/write the values of these variables based on their addresses. I have reviewed the examples of PyXCP, but they do not work. Could you help provide an example relevant to my requirements? Thank you very much.

Here is a general guideline for reading and writing once you successfully stablished connecting with your slave:

For reading you have two options, polling and DAQ. If you want to read data through polling you can user the shortUpload and upload methods, the size of the XCP packet determines which one you should use (you can calculate the length of the variable with the data type inside the A2L).

For writing, just like in poll based reading you can use shortDownload and download methods (again you have to calculate the size of the XCP packet just like I mentioned above). Just make sure to pack the data with the corresponding length and data type (you can find this information inside the variable definition in the A2L file).

Note: Be aware if the signal is an array of values or a single value, this affects the length calculation.

@JavierCorado Hi thank trying to use this solution for my case(#183)

but iam failing with initiate the argument parser:
ap = ArgumentParser()
with ap.run() as x:
x.connect()

iam requested to create the conf_file: pyxcp_conf.py

what should i put there if these are my configurations:
i use ethernet, UDP communication, IPV6 host
receive on:
Debug PC
IPv4: 192.168.X.X
IPv6: XXXXXXXXXXXXXXXX
UDP Port: 5555
VLANID: 2
MAC Address: XXXXXXXxX

send to ECU:
PH XCP Slave (KVS):
IPv6: XXXXXXXXXX
UDP Port: XXXX

can you share an example hoe to initiate https://github.com/christoph2/pyxcp/blob/master/pyxcp/cmdline.py ?

Well, pyXCP s basically about XCP and pya2ldb is about A2L...
The interaction of these and other projects will be the task of asamint.

I've created a small example to show the basic procedure of running a DAQ list measurement (Tested with XCPlite).

Note: pya2ldb uses SQLAlchemy under the hood, so arbitrary complex queries are possible, but for the sake of simplicity the example code selects all MEASUREMENTs.

Tip: There is a small command-line utility xcp_fetch_a2l that can be used to fetch the correspondending A2L file.

import time

from pyxcp.cmdline import ArgumentParser
from pyxcp.daq_stim import DaqList, DaqRecorder

from pya2l import DB
from pya2l import model

A2L_FILE = "C_Demo" # No extension -- .a2l is assumed.

db = DB()
session = db.open_create(A2L_FILE)  # Import A2L or open existing .a2ldb

ASAM_TYPE_MAP = {
    "UBYTE": "U8",
    "SBYTE": "I8",
    "UWORD": "U16",
    "SWORD": "I16",
    "ULONG": "U32",
    "SLONG": "I32",
    "A_UINT64": "U64",
    "A_INT64": "I64",
    "FLOAT16_IEEE": "F16",
    "FLOAT32_IEEE": "F32",
    "FLOAT64_IEEE": "F64",
}        
    
measurements = []
for m in session.query(model.Measurement).order_by(model.Measurement.name).all():
    name = m.name
    address = m.ecu_address.address
    address_ext = m.ecu_address_extension.extension if m.ecu_address_extension else 0
    asam_type = m.datatype
    data_type = ASAM_TYPE_MAP.get(asam_type)

    # You may check here if the measurement should be used.
    measurements.append((name, address, address_ext, data_type, ))
    print(f"MEASUREMENT:  {name:<20s} address: 0x{address:08x}:{address_ext}  -- type: {asam_type!r}")


ap = ArgumentParser(description="DAQ test")

EVENT_CHANNEL = 0

daq_lists = [
    DaqList(
        "demo_measurement",
        EVENT_CHANNEL,
        False, # List is DAQ not STIM.
        True,  # Use DAQ timestamps if available.
        measurements,
    )
]

daq_parser = DaqRecorder(daq_lists, "demo_measurement", 1)

with ap.run(policy=daq_parser) as x:
    x.connect()
    if x.slaveProperties.optionalCommMode:
        x.getCommModeInfo()

    x.cond_unlock("DAQ")  # DAQ resource is locked in many cases.

    print("setup DAQ lists.")
    daq_parser.setup()
    print("start DAQ lists.")
    daq_parser.start()

    time.sleep(5 * 60)  # Run for 5 minutes.

    print("Stop DAQ....")
    daq_parser.stop()
    print("finalize DAQ lists.\n")
    x.disconnect()

Regarding basic setup:

First create a configuration file:

xcp-profile create -o pyxcp_conf.py

Then edit pyxcp_conf.py, the relevant lines in case of XCPonEth are:

c.Transport.layer="ETH"

c.Transport.Eth.port=5555
c.Transport.Eth.protocol="UDP"  # or TCP

c.Transport.Eth.host="localhost"  # name or IP of XCP slave

# c.General.seed_n_key_dll="SeedNKeyXcp.dll"   # optional name of Seed-and-Key .dll

A good starting point is the script xcp_info, which gathers some useful information (If a Seed-and-Key .dll is required, you'll notice here...)

I forget to mention:
If the measurement was successful, one can use ex_arrow.py, ex_csv.py, ex_excel.py, ex_mdf.py, ex_sqlite.py to convert from the measurement file (demo_measurement.xmraw in this case) to common file formats.

The necessary dependencies like pyarrow, asammdf, ... are not installed by pyXCP.

Hi thanks !!
2 questions:
1
my pyxcp_conf looks line:
c = get_config() # noqa
c.Transport.layer="ETH"

c.Transport.Eth.protocol="UDP" # or TCP
c.Transport.Eth.ipv6 = True
c.Transport.Eth.bind_to_address="fd53:........masterIPV6"
c.Transport.Eth.bind_to_port=5556

c.Transport.Eth.host = "FD53:......slave ip"
c.Transport.Eth.port=5556 - his is the master port? where should i insert the slave port??

  1. trying to run pyxcp/scripts/xcp_info.py , stuck on:
    \pyxcp\master\errorhandler.py
    executor = Executor()
    res = executor(inst, func, arguments)
    why?

I use this code:

import time
from pyxcp.cmdline import ArgumentParser
from pyxcp.daq_stim import DaqList, DaqRecorder
import logging

logging.basicConfig(level=logging.DEBUG)

# Define measurements directly
measurements = [

logging.info("DAQ Measurements: %s", measurements)

daq_lists = [
    DaqList(
        "demo_measurement",
        0,    # EVENT_CHANNEL
        False,  # List is DAQ not STIM.
        True,   # Use DAQ timestamps if available.
        measurements,
    )
]

logging.info("Init DAQ Argument Parser")
ap = ArgumentParser(description="DAQ test")

daq_parser = DaqRecorder(daq_lists, "demo_measurement", 1)
logging.info("Initialized DAQ Recorder")

try:
    with ap.run(policy=daq_parser) as x:
        # logging.info("Connecting to ECU...")
        x.connect()
        # logging.info("Connected to ECU via XCP on CAN")
        if x.slaveProperties.optionalCommMode:
            x.getCommModeInfo()

        x.cond_unlock("DAQ")  # Unlock DAQ resource if locked.

        # logging.info("Setting up DAQ lists...")
        try:
            daq_parser.setup()
        except Exception as e:
            logging.error(f"Failed to setup DAQ lists: {e}")
        
        # logging.info("Starting DAQ...")
        daq_parser.start()

        time.sleep(60)  # Run for 60 seconds.

        # logging.info("Stopping DAQ...")
        daq_parser.stop()

        x.disconnect()
except Exception as e:

Currently, I am unable to resolve this issue. Can you help me?

Is the SYNCH issue repeateable?
Could you disable the try/except block, an execption trace would be really helpful.
You could also try to run xcp-info, maybe the outcome is different...

My final proposal is to see the values of all measurements and characteristics on the ECU, which are defined in the A2L file

Hard to diagnose with zero information...

  • There is a timeout at the UPLOAD command followed by a SYNCH command, this seems reproduceable; you haven't told me.
  • Have you ever tried to run without loglevel=DEBUG?
    logging has currently an adverse effect on performance, don't activate for no reason!
    If the error still persists, probably something is wrong with your XCP slave.
  • I don't know what is the output of xcp-info.
  • Looks like a plain Python exception trace -- did you for any reason disable rich.traceback?

error: required argument is not an integer

If you need any additional information, please let me know.

Maybe really an configuration issues ?
An empty response from GET_ID / Implemented IDs is rather uncommon...

Also, to preclude a systematic error of the UPLOAD command you should try to read a known-good address (from you A2L),
something like this:

LEN = 4
ADDR = 4711
x.setMta(ADDR)
data = x.fetch(LEN)

You should also give XCPlite a chance, to have a working reference system (I'll include a Dockerfile in the next release, that simply works...)

Currently, I have three issues that I need your support with.

  1. daq_parser.start() issue

I resolved the previous issue, but now I’m facing a new problem: I cannot stop the DAQ because start_stop_synch is not functioning.My program often stops immediately after the daq_parser.start() command, even though it still sends the message DD 01. It doesn’t display any error for this issue, whether DEBUG mode is enabled or not.

  1. My second question is whether there is a way to directly retrieve the values of the variables without having to export to XMRAW and then convert to CSV or Excel. Are the measured variable values stored in a list, dictionary, or something similar?
  2. Additionally, could you specify which function you are using to decode DAQ/ShortUpload messages into actual values based on their hexadecimal format and data type, such as FLOAT32_IEEE, UBYTE, or UWORD? Does the library already provide a function that directly supports this? Please point it out if available.

You are helping me a lot with my project. Thank you very much!

Looks much like that the recorder extension crashes -- this was an older issue., please make sure to use the latest pyXCP version,
in any case run
pip install -e .
to rebuild the C++ extensions.

Coming to your second question: No, it is not required to record first and then do some post-processing; it's also
possible to process DAQ lists live, as they are received.

For an example s. DaqToCsv class, you may use this as an starting point.
The interface of the base class has three methods that must be overriden (C++ pure virtual methods under the hood):

   def initialize(self):
       pass

   def on_daq_list(self, daq_list: int, ts0: int, ts1: int, payload: list):
      pass # Live processing here.

   def finalize(self):
       pass

initialize and finalize can be used to setup/close resources like files.

The parameters of on_daq_list are:

  • daq_list: the number of the DAQ list received.
  • ts0: Timestamp generated py pyXCP.
  • ts1: Timestamp from DAQ list (if available)
  • payload: a list of the converted measurement values.

The conversion routines are included in the fiile unfolder.hpp.
They are used to convert the raw bytes to the desired datatype values (byte-order is taken into account), i.e. the last parameter in the measurements definition, e.g.:

            ("swordCounter", 0x20414, 0, "I16"),
            ("sdwordCounter", 0x20418, 0, "I32"),
            ("channel1", 0x203F8, 0, "F64"),
            ("channel2", 0x20400, 0, "F64"),
            ("channel3", 0x20408, 0, "F64"),

Conversion is currently not available in the Python space, i.e. only raw byte values from UPLOAD/SHORT_UPLOAD ;
but a decent polling mode API could be added.

@PCT-VF can you share your config file(pyxcp_conf.py)?

failing on: daq_parser.setup()

how can i define it? and what if i dont want to read it from a2l file?
Thanks again for your support!!

This is my config inpyxcp_conf.py

c = get_config()  # noqa
c.Transport.layer = 'CAN'
c.Transport.Can.interface = 'vector'
c.Transport.Can.can_id_master = 0x7B1  # Master CAN ID
c.Transport.Can.can_id_slave  = 0x782  # Slave CAN ID
c.Transport.Can.channel = 0  # CAN channel (e.g., 0 for Kvaser channel 0)
c.Transport.Can.bitrate = 500000  # CAN bitrate
c.Transport.Can.Vector.app_name = 'python-can'

In my code, I define measurement list directly instead of using A2L file, you can use it as a example.

measurements = [
("COM_WindowPositionFL", 0x3434CA50, 0, "U8"),
("COM_WindowLockDSBBtnPress", 0x3434CA51, 0, "U8"),
("COM_WindowFRThermalProtect", 0x3434CA52, 0, "U8"),
("COM_WindowFRSuppressionWarn", 0x3434CA53, 0, "U8"),
]

I haven't ever seen your error, however, if you provide more infomation, maybe I can help you.

Hi @PCT-VF thanks again!
i have 2 file in my program

  i tried to run the code and got the error about a2l file, but i dont want to use a2l file:
failing on: daq_parser.setup()
Failed to setup DAQ lists: SystemExit(error_code=ERR_CMD_UNKNOWN, message='Could not proceed due to unhandled error (USE_A2L).')

do you know where is defined to look for a2l file?
Thanks again for your support!!
