Chapter 8 Sample Program

The V850 ZigBee

TM

 Gateway sample utilizes several complex libraries in order to

provide a wireless-to-Ethernet gateway solution for application development. In
this section, we will identify the key user configurable files that will allow the
solution to be tailored to the user’s application. However, it is recommended that
the users familiarize themselves with the MAC and CNET library documentation.

8.1 User configurable network Parameters

Various network parameters will always be user specific and must be tailored to
the user application; these user configurable parameters can be found in the
“config.h” header file.

8.2 Libraries

The following provides a brief overview libraries supplied with the 

V850

ZigBee

TM

 Gateway Development Platform

.

Table 8-1 Different libraries used

API.R85

API interface for the CNETTCPIP stack.

Cnet_osless.R85

Required to ensure correct operation of the TCPIP stack when
No RTOS is employed.

Config.R85

Various system configuration utilities.

Driver.R85

Library for the Ethernet device driver.

NEC.R85

NEC Utilities and applications library.

Sellib.R85

Flash Self programming library.

Stack.R85

IEEE.802.15.4 MAC stack library.

Webpages.R85

Library containing the web pages, the web pages are also
supplied as source code so that the user can modify the web
pages. Care must be taken to use the same names for the web
pages so that at link time the web page library is not called. Web
pages can generate large code sizes so care must be in the
design to ensure that the 64KB code size limit is not exceeded.

8.3 Embedded functions in Web Pages

All of the embedded functions that are called from the web interface can be found
in the file 

“httpdfunc.c”

; should the user wish to change the functionality of the

web calls please modify the code appropriately.

A utility program is provided to convert web pages (see accompanying CNET user
manual) to a large data array; this data is placed in a file called 

“fsdata.c”

. After

conversion this file needs to be modified with the following to ensure the web
pages are located in the correct segment of memory.
