We would like to help, but need more information about the application.
You will as a minimum need to set up a ramdisk to hold the real-time
data, but should probably consider battery backed RAM to hold the
real-time data so that you won't lose data in the event of a power
failure. TS is working on making their battery backed RAM appear as a
mounted disk drive.
Remember, do NOT write continuously to flash, it has limited write
cycles. Though, TS uses a special file system for flash to distribute
the writes, with a 1 GB flash, you would probably last years writing
100 bytes per second and that might be cheaper and easier than buying
battery backed RAM. I am actually considering this because the the
battery backed RAM boards are very bulking and cost over $100 for 2
meg. I would take 3 years to fill a 1 GB flash writing 100 bytes per
second.
To get started, I would reccomend generating straight html for your
real-time displays. If you add the following to the top of your file,
this will force a refresh every second.
<META HTTP-EQUIV="refresh" CONTENT="1">
<meta http-equiv="pragma" content="no-cache">
Also, you should use Firefox since it works so much better for
real-time displays. Internet Explorer insists on scrolling to the top
of the page on refresh, rather than leaving you where you were, and
also gives a lot of blink. With Firefox, you don't get all the blink.
You can also use overlapping images to create interesting animations,
though you can not rotate. You can even use transparency with png
images. Here is an example:
<div style="position:absolute; top:50px; left:0px;">
<img SRC=Line1_1024.png>
</div>
<div style="position:absolute; top:95px; left:26px; z-index:2">
<img SRC=square10x10.png>
</div>
Well, give us some more information and we can help you.
Do you know how to use the C compiler and transfer files to the SBC?
Do you understand the basics of Apache? Apache is turned on by
default.
