8.3 Development Environment

8.3.1 Development Environment

To develop application programs a 16-bit compiler, Microsoft C/C ++ 7.0 or later, and a computer

on which the compiler can run are required.

8.3.2 Application Development Library

For this terminal various libraries such as the keypad library and OBR library, which is used to

enhance the efficiency of developing applications. This terminal is also provided with the libraries

of controlling the IT-2000 dedicated devices such as the backlight control and device power control,

etc. However, those processes which depend on interfaces of hardware are managed with DLL, and

the dedicated functions cannot be linked to application program directly.

Note:

In case Visual BASIC is used as the development language, the libraries in boxes with

broken-dot-line in Fig. 8.1 are not needed.
