6.5 Run the PINGME.C Sample Program
Connect the crossover cable from your computer’s Ethernet port to the RCM3750
module’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 LINK light on the RCM3750 module should be on to
indicate an Ethernet connection is made. (Note: If the LNK light does not light, you may
not be using a crossover cable, or if you are using a hub perhaps the power is 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 yellow ACT light flashes on the RCM3750 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\RCM3700\TCPIP\
and the SAMPLES\RCM3720\TCPIP\ folders.
The program BROWSELED.C demonstrates how to make the RCM3750 module 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 RCM3700
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.
