InnoMakerUsb2CanLib

[rzucca]

I wrote a programme for writing/reading data to/from a device over CAN.

It works fine when I use PEAK CAN as an interface because I can use the inbuilt QCanBus plugin.
I had less luck when trying to use the innomaker USB2CAN interface because I am not able to link and compile the InnoMakerUsb2CanLib dynamic libraries.

Any advice?

Any more information? Like error messages, OS, Qt version? Did you build these libraries? If you downloaded prebuild libraries - were they built using same compiler?

Hello. Sorry for the missing information, I was just at the start and having difficulties to link the inno prebuilt library (.h, lib, dll) to my project.
I'm using Qt 6.8.2 MSVC2022 for Windows and I got the libraries at the GitHub page of INNO-MAKER/usb2can
After some trial and lots of errors, I found out how to link the libraries and connect to the target.
For reference, if anyone reading is having the same difficulties as I, I added the following lines to the pro file:

win32: LIBS += -L$$PWD/include/ -lInnoMakerUsb2CanLib

INCLUDEPATH += $$PWD/''
DEPENDPATH += $$PWD/''

I still can't send or read CAN messages, though. I am afraid, it has more to do with my lack of skills (coupled with to non-existing library documentation) and is not strictly a technical problem I have with Qt. The only thing I know is that the driver function sendInnoMakerDeviceBuf is returning false

@rzucca have you already seen https://github.com/INNO-MAKER/usb2can/tree/master/For Windows/QT/QT/QTInnoMaker ?

That looks like an useful example for you.
