Chapter 1. The Programming interface

of AnaGate devices

The AnaGate product line consist of several hardware devices, which offers access to different bus systems

(I2C, SPI, CAN) or processors (Renesas) via standard network protocol.

The communication to the individual devices always is done through a documented and disclosed

proprietary network protocol. Thus, all products which incorporates a socket interface (like personal

computers, PLC, ...) are allowed to access the devices of the AnaGate product line.

Analytica provides a programming interface for users of Windows and Linux operating systems (X86)

which implements the proprietary communication protocol and make it available through simple function

calls. The software API (Application Programming Interface) is available free of charge for Windows and

Linux operarting systems.

Note

To provide a widespread support of differrent programming languages like C++, Visual

Basic, Delphi and the programming languages of the .NET family, the cdecl calling

convention is used in all function calls. Using this calling convention means that all function

parameters are pushed on the stack in reverse order (from right to left) and that the caller

is responsible for the stack handling. Most programming languages support this calling

convention.

The different libraries include common and specific functions which are neccessary for accessing and

controlling the devices of the AnaGate product line. In the following, all library functions of the software

API are documented in detail.
