8.3.1Development 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.

8.3.2Application 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.
