Chapter 4 - Writing the SDK Application
The SY7000 SDK runs give the user the ability to develop an C++/C application which accesses and
control the S Y7000 functionality terminal like (Keyboard, LEDs, card readers, Buzzer, Relay).
The SDK is based on the following libraries that are supplied in the CD:
GLibC – GNU C Library
The C language provides build-in facilities for performing such common operations as input/output,
memory management, string manipulation and the like. The GNU C library core is an ANSI/ISO standard
C library. GNU C also includes extension compatibility with Posix, BSD, SUID, and XPG.
Interface Library
Simple and easy to use, the interface library is event driven and multi-threaded. The user application can
be a single threaded program. The simplicity of the interface library removes the complexity of file and
event I/O and also removes the need for low level hardware interfacing.
LibNE7000Pik – is the high level library, written in C++. The purpose of this library is to extend the low
level library and give it the ability to manage and control events, and terminal functionality using a simple
API.
The classes of this library are described below.
LibNE – is the low level library written in C. This library is closer to the hardware and the user rarely
needs to access the functions of this library because it is extended by the high level functionality of
LibNE7000Pik .
