CAN API V3 is a wrapper specification to have a uniform CAN Interface API for various CAN interfaces from different vendors running under multiple operating systems.
This repo contains the source code for a CAN API V3 compatible wrapper library under Windows for CAN Interfaces from Kvaser AB, Sweden. The wrapper library is build upon Kvaser´s CANlib SDK.

Important note: To build any of the following build targets run the script build_no.bat to generate a pseudo build number.
C:\Users\haumea>cd C:\Projects\CAN\Drivers\KvaserCAN
C:\Projects\CAN\Drivers\KvaserCAN>build_no.bat
Repeat this step after each git commit, git pull, git clone, etc.
To build all 32-bit targets (x86) run the script x86_build.bat.
C:\Users\haumea>cd C:\Projects\CAN\Drivers\KvaserCAN
C:\Projects\CAN\Drivers\KvaserCAN>x86_build.bat
To build all 64-bit targets (x64) run the script x64_build.bat.
C:\Users\haumea>cd C:\Projects\CAN\Drivers\KvaserCAN
C:\Projects\CAN\Drivers\KvaserCAN>x64_build.bat

can_moni is a command line tool to view incoming CAN messages.
I hate this messing around with binary masks for identifier filtering.
So I wrote this little program to have an exclude list for single identifiers or identifier ranges (see program option /EXCLUDE or just /X). Precede the list with a ~ and you get an include list.

can_test is a command line tool to test CAN communication.
Originally developed for electronic environmental tests on an embedded Linux system with SocketCAN, I´m using it for many years as a traffic generator for CAN stress-tests.
