RWEB_IO_SAMPLE.C
—Demonstrates using RabbitWeb to display the status of multiple I/O
lines (analog and digital) in a Web browser, and allows the user to change the digital
outputs by clicking the buttons on the page.
The sample program uses an IFRAME (invisible frame) to refresh the I/O readings
every two seconds. Since the Web browser does not have to re-render the entire page,
updates are quick and flicker free.
Once the sample program is compiled and running, open your PC Web browser. 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
Now use a wire to touch +5 V from header J4 on the BL4S100 to the various digital and
analog inputs on header J3, J15, and J16
•
SMTP.C
—Uses the SMTP library to send an e-mail when a pushbutton switch on the
Demonstration Board is pressed.
•
TELNET.C
—Allows you to communicate with the BL4S100 using the Telnet protocol.
This program takes anything that comes in on a port and sends it out Serial Port D and
displays the content in the Dynamic C
STDIO
window. It uses a digital input to indicate
that the TCP/IP connection should be closed and a digital output to toggle an LED to
indicate that there is an active connection.
Once the sample program is compiled and running, start the Telnet program on your PC
(
Start > Run
telnet 10.10.6.100
). As long as you have not modified the
TCPCONFIG 1
macro in
the sample program, the IP address is 10.10.6.100 as shown; otherwise use the TCP/IP
settings you entered in the
TCP_CONFIG.LIB
library. Each character you type will be
printed in Dynamic C's
STDIO
window, indicating that the board is receiving the char-
acters typed via TCP/IP.
