Demo Programs

Every TCP/IP demo program must know which Ethernet driver it should use. Since On Time RTOS-32 is not a plug-and-play operating system, the demos will not automatically detect what network hardware is installed. Rather, this information is supplied in include file Netcfg.h, which is part of every included demo.

This is the default content of Netcfg.h:

// #define DHCP       // if you enable this, you must also 
                      // link library dhcpc.lib 

#if defined(DHCP)     // use DHCP 
   ... 
#else                 // static IP address assignment (default) 
   static BYTE TargetIP[]       = {192, 168,   1,  10}; 
   static BYTE NetMask[]        = {255, 255, 255,   0}; 
   static BYTE DefaultGateway[] = {192, 168,   1,   1}; 
   static BYTE DNSServer[]      = {192, 168,   1,   1}; 
#endif 

// #define DEVICE_ID  NE2000_DEVICE  // define your device type here 
#define DEVICE_MINOR  0              // first device of type DEVICE_ID 

#ifndef DEVICE_ID 
   #error You must define network driver/resources here 
#endif 

...

The NetMask, TargetIP, DefaultGateway, and DNSServer constants are only used by demos which do not use (or are not configured to use) DHCP. You can set DefaultGateway and DNSServer to 0.0.0.0 if you do not intend to use the demo to communicate outside the local LAN segment. With DHCP enabled, all required values are requested from a DHCP server which must be present on the LAN.

The DEVICE_ID specifies which driver shall be used on the target. The following values are available:
