PCAN - Matlab Dll Issue

[pietmanheyns]

Hi all,

I am using a PEAK CAN-USB converter (item number IPEH-002021) to communicate with a servo drive via matlab. I only recently started using load-library files in Matlab and I'm having a bit of difficulty communicating to the PCAN converter using matlab.

I loaded the pcanbasic.dll file with the pcanbasic.h headerfile using the loadlibrary function, the library gets loaded and I can view the functions using the libfunctions('libname') file, but its loaded with a lot of errors (Warning: The data type 'error' used by function CAN_initialize does not exist).

When I try calling a function using calllib function, I get the error: Error using ==> calllib, no method with matching signature.

Has anyone come across this problem or does anyone know what I am doing wrong?

Any help would be greatly appreciated.
Kind regards,

Pieter

Hi,

did you see the following post with some Matlab examples for PCAN-Light:

perhaps this will help

Hi Michael,

Thank you for the reply and the info.
I'm not using simulink at all to communicate to the PCAN module, the comments and information of the post is not applicable to my problem.
Thank you anycase.
Regards,
Pieter

We also have a simple MATLAB implementation (without ANY support) free of charge for the older PCAN-Light API (unzip with PW: peak)

Hi,

i am getting the following error when i amtrying to compile the matlab dll on my win7 64 bit machine.

Error in Build_DLL (line 2)

Does anyone have an idea what's the problem?

Thx in advance!

The LIB file´s are 32Bit LIB´s and could not used to create 64Bit code.
Please Download the latest 32/64Bit Light package and use the 64Bit LIBs on a 64Bit System.
DOWNLOAD PCAN-Light package
