PCAN USB Hardware ID - Python

Post by Pbreaction1 » Tue 12. Jun 2012, 17:37

I am wondering what i am doing wrong... With the code displayed i expected the return to be 5 or 5h on the GetValue() method.

Any help would be greatly appreciated.


Thanks in advance,

Mark

you use the wrong PARAMETER when calling CAN_GetValue - please use PCAN_DEVICE_NUMBER
PCAN_DEVICE_NUMBER

Access:
Description: This parameter is used on PCAN-USB hardware to distinguish between 2 (or more) of them on the same computer. This value is persistent, i.e. the identifier will not be lost after disconnecting and connecting again the hardware.

Possible values: According with the Firmware version, this value can be a number in the range 1-255 or 1-4294967295. If the Firmware has a resolution of one byte and the specified value is bigger, than the value is truncated.

Default value: If this parameter was never set before, the value is the maximum value possible for the used resolution. For 8-bits: 255 (FFh), for 32 bits: 429496729 (FFFFFFFFh).

PCAN-Device: PCAN-USB.

Why am I only able to read the PCAN_DEVICE_NUMBER one time for the PCAN-USB?

After I initialize, I am able to call GetValue on the PCAN_DEVICE_NUMBER; however, any subsequent calls for the PCAN_DEVICE_NUMBER I will get a PCAN_ERROR_UNKNOWN error returned. In order to reset, I would have to unplug the USB device and replug it in.

This happens only with the PCAN-USB and not the PCAN-USB Pro
I am able to call GetValue for PCAN_DEVICE_NUMBER on the PCAN-USB Pro many times with no error.

Hello,

please share some code as well as information (driver version, API version, etc). Without it we cannot tell you if or where something could go wrong. A small test shows that the behavior you describe is not reproducible, at least with our python version...

You can use the Python sample delivered within the PCAN-Basic package to test this (PCANBasicExample.pyw). There you can initialize a device and then ask for its ID just by clicking a button...

Hi Keneth,

Thanks for the reply.
I am using API Version 4.1.0.2. Channel Version 8.1.0.

I tried your code input and it works when I execute it in the python command line; however, when I move it to a file and execute it multiple times, it does not.

when I run:
$ python test.py
This will work the first time, but not subsequently (again, this only happens with PCAN-USB and not PCAN-USB Pro)

Here is the code contained within test.py

Code: Select all

from PCANBasic import *

pcb = PCANBasic()
pcb.Initialize(PCAN_USBBUS1, PCAN_BAUD_500K)

print(pcb.GetValue(PCAN_USBBUS1, PCAN_DEVICE_NUMBER))

pcb.Uninitialize(PCAN_USBBUS1)

Hello,

It seems you are using the linux version of the PCANBasic API, could you tell us what is the version of the linux PCAN driver and your kernel version by returning the output of the following commands ?

Code: Select all

$ cat /proc/pcan
$ uname -a
Note that we strongly recommand to use the PCAN driver linux 8.x versions.

Thank you.
Best regards,
Fabrice

Hello,

Obviously the second time you call the script, PCANBasic returns an error when calling pcb.GetValue.. It indicates a system error.
Since we can't reproduce the issue, we have to investigate what happens within your driver, can you please return the output of the following commands :

Code: Select all

# outputs system message
dmesg | grep pcan
# call the "get_device_number" test script 
python3 test.py
# call again the test script to generate an error
python3 test.py
# outputs system message
dmesg | grep pcan
Thank you.
Best regards,
Fabrice
