6.4.1 How to Set IP Addresses in the Sample Programs
With the introduction of Dynamic C 7.30 we have taken steps to make it easier to run
many of our sample programs. You will see a
TCPCONFIG
macro. This macro tells
Dynamic C to select your configuration from a list of default configurations. You will
have three choices when you encounter a sample program with the
TCPCONFIG
macro.
1. You can replace the
TCPCONFIG
macro with individual
MY_IP_ADDRESS
,
MY_NET-
MASK
,
MY_GATEWAY
, and
MY_NAMESERVER
macros in each program.
2. You can leave
TCPCONFIG
at the usual default of 1, which will set the IP configurations
to
10.10.6.100
, the netmask to
255.255.255.0
, and the nameserver and gateway
to
10.10.6.1
. If you would like to change the default values, for example, to use an IP
address of
10.1.1.2
for the RCM3305/RCM3315 board, and
10.1.1.1
for your PC,
you can edit the values in the section that directly follows the “General Configuration”
comment in the
TCP_CONFIG.LIB
library. You will find this library in the
LIB\TCPIP
directory.
3. You can create a
CUSTOM_CONFIG.LIB
library and use a
TCPCONFIG
value greater
than 100. Instructions for doing this are at the beginning of the
TCP_CONFIG.LIB
library in the
LIB\TCPIP
directory.
There are some other “standard” configurations for
TCPCONFIG
that let you select differ-
ent features such as DHCP. Their values are documented at the top of the
TCP_CON-
FIG.LIB
library in the
LIB\TCPIP
directory. More information is available in the
Dynamic C TCP/IP User’s Manual .
