I can't remember the location, but search for index.html:
find / -name index.html
Just change that file and add others under the same directory. You can
then write files every 5 seconds say, generated with real-time values.
I think I already gave you the code to force the browser on the client
side to refresh periodically. You should eventually use file locking,
but to start, just write the files. You can also write cgi files in C
to send outputs from a browser on a remote computer. Of course keep
this on a private network!!

You first need to download and install the cross compiler under /opt
Then add the following to the path:
/opt/crosstool/arm-linux/gcc-3.3.4-glibc-2.3.2/bin/
You can insert this into your .bash_profile file:
PATH=/opt/crosstool/arm-linux/gcc-3.3.4-glibc-2.3.2
/bin/:$PATH
export PATH
gcc is: arm-linux-gcc
g++ is: arm-linux-g++
I have attached a makefile that compiles all of my programs and puts
them an a directory called "arm", to keep them separate from ones that
run locally. I compile programs for Fedora, TS SBCs, and Sixnet RTUs,
so need to keep it all separate.
Make sure you use the compiler option: -mcpu=arm9
If you want to create your own libraries to run on the arm sbc, you need to copy the shared object to:
/opt/crosstool/arm-linux/gcc-
3.3.4-glibc-2.3.2/lib/gcc-lib/arm-linux/3.3.4/
This is so the cross compiler can also find them and verify all the
library calls at compile time. You also need to copy them to
/usr/local/lib on the target SBC and run ldconfig.
It really is quite simple!!

look at the example code for the LCD display and keypad, and also read
the manuals. You will see how to set each pin as either input or
output. If you have specific questions after looking at that code and
after reading the manual let us know. On 4/26/06, francis joss <

To transfer files to the 7200 you should use
FTP, but you need to get
the ethernet connection going first. You really only need to set the
IP on your computer to a fixed IP using the same address range as the
7200 default, such as
192.168.0.5. The default IP of the 7200 should
be 192.168.0.50.
Actually, from the command prompt, type "ifconfig" to verify the
default IP of your 7200 is in fact 192.168.0.50.
Once you have the ethernet connection working, you can also telnet to
the 7200. Of course in a browser window, type in http://192.168.0.50
and you should see
the default TS web page.
Well, you need to look for someone locally that has experience with
Linux or Unix in general. We can't help you with everything via the
email list.
Also, if you describe you application, you will get a lot more
helpfull suggestions.
