Principle Description of the API

The PCAN-Basic API is the interface between the user application
and device driver. In Windows operating systems this is a DLL
(Dynamic Link Library).
The sequence of accessing the CAN interface is divided into three
phases:
1. Initialization
2. Interaction
3. Completion
Initialization
A channel must be initialized before using it. This is done by the
simple call of the function
CAN_InitializeFD
hardware, up to 16 CAN channels can be opened at the same time.
After a successful initialization the CAN channel is ready. No further
configuration steps are required.
