2 Software
The software consists of two parts. One part is
executed by the microprocessor inside
CPC-XTI. The application program runs on the
PC and makes use of the interface library.
2.1 Functions of CPC-XTI
CPC-XTI offers enhanced functionality for
CAN communication:
•
Transmission and reception of
CAN-messages
• Filtering and buffering of received mes-
sages
• Measurement of bus-load
The functions of CPC-XTI are accessed
across the interface library of the PC.
2.2 Application program: Realization Concepts
The library of interface functions supports two
ways to implement the application program.
The synchronous mode complies with
conventional programming. The sequence of
program steps is given by the program
structure. Asynchronous mode allows event
driven programming similar to the way used in
graphical user interfaces.
