The following sections of the Narrowband Chipset Device Driver Manual describe the
Narrowband Chipset device driver. The chipset driver is written in ANSI-C programming
language to promote greater driver portability to other embedded hardware and Real Time
Operating System environments.
Section 2 gives an overview of the Narrowband chipset and the main features provided by the
chipset driver to the user from an application perspective. Section 3 defines the software
architecture of the Narrowband Chipset driver. It also includes a discussion of the driver’s
external interface and its main components. The Data Structure information in Section 4 describes
the elements of the driver that either configure or control its behavior. Included here are the
constants, variables, and structures that the Narrowband Chipset device driver uses to store
initialization, configuration, and status information. Section 5 provides a detailed description of
each function that is a member of the Narrowband Chipset driver Application Programming
Interface (API). This section outlines function calls that hide device-specific details and
application callbacks that notify the user of significant events.
For your convenience, Section 8 of this manual provides a brief guide for porting the Narrowband
Chipset driver to your hardware and RTOS platform. In addition, an extensive Appendix (page
178) and Index (page 257) provides you with useful reference information.
