Erreur Code

[MOUHOUBI]

Hello,

I tried this python code to read a message, this example I found it on this forum but I have this error message:

Code: Select all

# The Plug & Play Channel (PCAN-USB) is initialized
#
objPCAN = PCANBasic()
result = objPCAN.Initialize(PCAN_USBBUS1, PCAN_BAUD_500K)
if result != PCAN_ERROR_OK:
    # An error occurred, get a text describing the error and show it
    #
    result = objPCAN.GetErrorText(result)
    print (result[1])
else:
    print ("PCAN-USB (Ch-1) was initialized")

readResult = PCAN_ERROR_OK,
while (readResult[0] & PCAN_ERROR_QRCVEMPTY) != PCAN_ERROR_QRCVEMPTY:
    # Check the receive queue for new messages
    #
    readResult = objPCAN.Read(PCAN_USBBUS1)
    if readResult[0] != PCAN_ERROR_QRCVEMPTY:
        # Process the received message
        #
        print ("A message was received")
        ProcessMessage(result[1],result[2]) # Possible processing function, ProcessMessage(msg,timestamp)
    else:
        # An error occurred, get a text describing the error and show it
        #
        result = objPCAN.GetErrorText(readResult[0])
        print (result[1])
        HandleReadError(readResult[0]) # Possible errors handling function, HandleError(function_result)

# The USB Channel is released
#
result = objPCAN.Uninitialize(PCAN_USBBUS1)
if result != PCAN_ERROR_OK:
    # An error occurred, get a text describing the error and show it
    #
    result = objPCAN.GetErrorText(result)
    print (result[1])
else:
    print ("PCAN-USB (Ch-1) was released")

Code: Select all

FileNotFoundError: Could not find module 'PCANBasic' (or one of its dependencies). Try using the full path with constructor syntax.

from what I understand he did not find the path to the PCANBasic library while I even added his path to PATH, how to do ?

thank you

Hello,

Python cannot find the library (PCANBasic.dll). Please make sure that you have the PCAN-Basic libraries in a place where python can find them. Normally (and best for beginners) is to use our PEAK-Drivers Setup to install the DLLs. Start the setup and install the feature "PCAN-Basic API"

Note that you already was instructed to do so in the other post from you, send and receive frame pyhton.

That does not give us any information that we could use to help you

i did everything you told me but i still have the same problem !!

post what exact is the problem - also do not start double post or we will remove all of them.
Also be sure that you have follow the instruction Keneth told you - it looks you did not. Check if you have any old DLLs anywhere on the PC - keep it clean!
