Little help on NE64 - Santiago - Nov 10 20:40:00 2005
Hello:
Well hello im trying to develop an applicattion using the ne64 for a
school project, the project is supposed to, using a tcp/ip connection,
monitore the status of some port or something like that. the problem
i have is this, i´ve managed to stablish the connection using telnet,
but it never ends the negotiation so it keeps trying to conect
indefinitly, the aplication monitores the atd register to send the
status of on/off of it, but cant recieve the info to complete the
process.
the question is have anyone some piece of software that can help me to
acomplish my task?? or knows a place where i can get it??
it would be great if anyone cuold help me.
thx.

See link http://www.ericengler.com/EmbeddedGNU.aspx
and check out Pierre Morency's uIP port. It a lot of the stuff you
are looking for.
Read doc if you haven't

Guessing you are trying to use the NE64 version of OpenTCP? If so
then you need to fix a few bugs in OpenTCP. As shipped the RTI isn't
running. Therefore the TCP timers are not working. However the http
server seems to work good enough most of the time.
Its only a school project? So "quick and dirty" is acceptable?
Suggest you study the http server and look into server-side includes.
Add a "file" to the http server. When that file is requested jump to
a routine which spits out http text containing the value of the
register you are trying to read. This way you don't have to write the
client side and can use telnet if you must, or any web browser.
OpenTCP doesn't buffer TCP I/O in a high level way. Your application
has to internally buffer its output so as to be able to resend it if
the TCP timers time out and request a retry.
The MC9S12NE64 demo kit from Freescale included CDs from http://
www.treck.com/ and http://www.cmx.com/ with demo versions of their
products including TCP/IP protocol stacks. If they work then they
can't be worse than OpenTCP. OTOH to use in a product they cost as
much as a modest new car.
Haven't looked closely at the CMX product but Treck's documentation
is very good.
As a school project you should get some Brownie Points for discussing
the difference between OpenTCP, CMX, and Treck products in your report.

Hi
Go to www.mjbc.ch.
We have a software packet called "uTasker" which we supply to
educational establishments without cost - presently it is Beta
testing. At the web site there are a number of on-line demos which you
can control with a standard browser and see on a webcam.
It runs on the NE64 demo board and includes operating sytem, TCP/IP
stack with the things you need, as well as a debugger and simulator.
It is configured to build with the GNU tools and IAR embedded
workbench.
Regards
Mark Butcher
