6.5 Run the PINGME.C Sample Program
Connect a Cat. 5 Ethernet cable from your computer’s Ethernet port to the RCM3900
board’s RJ-45 Ethernet connector. Open this sample program from the SAMPLES\TCPIP\
ICMP
folder, compile the program, and start it running under Dynamic C. When the program
starts running, the green LNK/ACT light on the RCM3900 module should be on to indicate
an Ethernet connection is made. (Note: If the LNK/ACT light does not light and you are
using a hub, check that the power is not off on the hub.)
The next step is to ping the board from your PC. This can be done by bringing up the MS-
DOS window and running the pingme program:
ping 10.10.6.100
or by Start > Run
and typing the entry
ping 10.10.6.100
Notice that the green LNK/ACT light flashes on the RCM3900 module while the ping is
taking place, and indicates the transfer of data. The ping routine will ping the board four
times and write a summary message on the screen describing the operation.
6.6 Running Additional Sample Programs With Direct Connect
The sample programs discussed here are in the Dynamic C SAMPLES\RCM3900\TCPIP\
folder.
The program BROWSELED.C demonstrates how to make the RCM3900 board be a Web
server. Two “LEDs” are created on the Web page, along with two buttons to toggle them.
Users can change the status of the lights from the Web browser. The LEDs on the Proto-
typing Board match the ones on the Web page. As long as you have not modified the
TCPCONFIG 1
macro in the sample program, enter the following server address in your
Web browser to bring up the Web page served by the sample program.
http://10.10.6.100.
Otherwise use the TCP/IP settings you entered in the TCP_CONFIG.LIB library.
The optional LCD/keypad module (see Appendix C) must be plugged in to the RCM3900
Prototyping Board when using this sample program. The sample program MBOXDEMO.C
implements a Web server that allows e-mail messages to be entered and then shown on the
LCD/keypad module. The keypad allows the user to scroll within messages, flip to other
e-mails, mark messages as read, and delete e-mails. When a new e-mail arrives, an LED
(on the Prototyping Board and LCD/keypad module) turns on, then turns back off once the
message has been marked as read. A log of all e-mail actions is kept, and can be displayed
in the Web browser. All current e-mails can also be read with the Web browser.
The sample program PINGLED.C demonstrates ICMP by pinging a remote host. It will
flash LEDs DS1 and DS2 on the Prototyping Board when a ping is sent and received.
