Fatal Python error: deallocating None

[zesoo]

There is a fatal error when I execute ./examples/transmit_canfd_example.py in WIN10 environment.

Message #414 NetID: 0x1 ArbID: 0x243 Data: ['0x48', '0x0', '0x1', '0x0', '0x0', '0x28', '0x26', '0x47'] Message #415 NetID: 0x1 ArbID: 0x533 Data: ['0x0', '0x0', '0x0', '0x0', '0x0', '0x0', '0x0', '0x0'] Fatal Python error: deallocating None Python runtime state: initialized

Current thread 0x00000c1c (most recent call first): File ".\transmit_canfd_example.py", line 115 in receive_can File ".\transmit_canfd_example.py", line 132 in Message #416

How can I fix it?

@zesoo Can you provide me details of the following:

1. Python Version (3.11)
2. Python architecture (32-bit or 64-bit)
3. python_ics version (914.x)
4. icsneo40.dll version (3.9.x.x)
5. Intrepid hardware in use (ValueCAN4-2, FIRE2, etc.)

4. how can I get this version?
5. ValueCAN4-2

[drebbe-intrepid]

@zesoo C:\Windows\System32\icsneo40.dll is the typical location. You can right click on it and go to properties to grab the version information.

The version is：3.9.15.14

@zesoo Thank you, I'm looking at it now to see if I can reproduce it.

@zesoo I can't reproduce this here but it looks like its crashing due to use of ExtraDataPtr (It shouldn't). Whatever Message #416 is, is creating the crash.

Can you change line 115 that reads this:

data = m.Data if not m.ExtraDataPtr else m.ExtraDataPtr

to this:

data = m.Data if not m.ExtraDataPtrEnabled else m.ExtraDataPtr

please and report back?

@drebbe-intrepid Thanks a lot,it worked,I wondering how to get the exact timestamp of the message.

 timeHw=m.TimeHardware|m.TimeHardware2<<32
 timeSys=m.TimeSystem|m.TimeSystem2<<32

Also you can keep this open, I'll update the examples to resolve this issue.

HI: I use the API get_timestamp_for_msg to get timestamp,

ts=ics.get_timestamp_for_msg(device,m)

but the result was 37 years off from the actual value.

@zesoo sorry for the late reply, ValueCAN4-2 doesn't have a battery for the RTC so you need to set the RTC when you open. See https://python-ics.readthedocs.io/en/master/index.html#ics.ics.set_rtc

Also the intrepid epoch is 1-1-2007.
