SXList embedded ethernet starter
contest.
This contest is now closed
For the new year, my goal is to get YOU involved in SX development especially
if:
-
You have worked with other microcontrollers and are looking for something
-
You have time but not necessarily money. Students, mature kids, hobbiests,
retired persons and devoted computer enthusiasts. SX processors are one of
the lowest cost systems to get started
with where you actually get a complete and professional development environment.
-
You like to learn new things but don't necessarily know anything about
computers. There is no better way to learn than to just get started...
To make that happen, starting in January 2002, I will:
-
Give away at least one
development system a month to
the most deserving applicant (in my humble opinion) who has written an original
SX program and is ready to debug it.
-
Give away Ethernet SX Stack Evaluation Kits like the ones used in the
SX FAST EMBEDDED ETHERNET
contest to anyone who presents me with source code for an SX stack application
that is ready to debug on the eval kit.
-
Answer questions, provide resources and make suggestions as needed... just
post using the form below and be sure to check back or include an email address.
What do you have to do? Just send me code...

Alberto Geraci of BTX Sistemas
says:
This project use the Ubicom SX28 micro controller to made a
digital reverb and echo effect from an
audio signal. It is for beginners, that want to learn more about A/D conversion,
read and write SRAM's and digital audio basics.
Winner: Alberto of course... how about some competition???

Phil says:
Here's my submission for the SXList contest. It's an
RS-232 humidity sensor. It's about 90% done and just needs debugging
and a bit of extra code (bitbanged RS232). All relevant files are attached,
assemble HUMID.ASM with MPASM. Add salt to taste :-)
Winner: Phil of course...

Randy Glenn says:
My entry for the contest is an SX-based contestant
lockout system, for 8-player, 2-team games, like Reach For The Top (where
Alex Trebek got his start). It's like Jeopardy, but with 2 teams of 4 members
each. One member answers the question by "buzzing in", at which point a tone
sounds, their light lights, and everyone else is locked out.
My system adds a twist - an auto-reset 4 seconds after the sound ends. This
is due to my own experiences, where moderators forget to reset the board,
and no one can buzz in for the next question.
The code uses the RTCC interrupt to generate the tone, and the RB interrupt
to detect when someone has buzzed in. I've designed it to run on a 4 MHz
oscillator, in Turbo mode. Details on hardware connections are in the attached
ASM file.
Winner: Randy of course... entering this contest is getting to be a sure
thing...

George F Hotz Says:
I entered in the ethernet starter contest, but
I wasn't able to finish my code. I have been working with SX microprocessors
for about a year now, but had some difficultly because I was never able to
debug (I have the SX-Blitz). When I saw this
contest I decided to write a
keyboard interface for the SX.(There are plenty for the PIC, but none
for the SX) I wanted it to write to an LCD the keyboard scan code. (Maybe
later it will support Ascii or a TV Out) For info on TV-Outs see
NTSC TV for the SX.
Winner: Duhh!

Aquarium Monitor V1.0 by Mike Woods. Designed
to grab the temperature and pH of an aquarium and send the data to a PC via
serial port. The PC then inserts the data into a database where the data
can be graphed and viewed from the web. I would like to skip the serial step
and have the SX directly insert data on my webserver. Listed below is the
link to the code and the PCB schematic zoomed out to make it easier to view.
All done for 1206 surface mount components. Eventually I will make the SX
itself surface mount with connectors to program directly. More information
on that will be available soon.
Winner: Ummm, with only one entry, who do you think won!

Hi I am interested in you reviewing this for you contest. I am interested
in the idea of microcontrollers and the SX28 seems so cool right now. At
19 it seems like I will be ahead of the class if I can start learning how
to use this stuff now. I also saw the ubicom ip2022 and that looks even better
than the sx but I think my time may be best spent learning the simpler one
right now. I do really like the idea of being able to incorporate ethernet
into a project. That just seems like it would literaly oopen up worlds to
me. I realize that my project is sort of "reinventing the wheel", I know
that ubicom already provides info on motor control, I haven't tried theirs
yet but I think mine might work pretty well.

SX On-hold messaging
switch The SX On-hold Messaging switch device adds a level of flexibility
to any company that has a PBX and wants to add Message or music on hold features,
they would be able to play different music or messages depending on which
external telephone line a call is on;
-
SX Weather StationThe Station is designed
to include Wind-speed and Direction, A Temperature sensor, a Barometric-pressure
sensor, a Humidity sensor, and a Rain-guage sensor. It is intended to be
built as a portable module to link up to an Ethernet cable and place on the
porch (for example). This would give the User a quick reference to outside
weather conditions (via an indoor PC), and allow the User to upload (to a
File, Database, etc) continuous Weather Data throughout the Day/Month/Year/etc.
The User could then project Daily/Seasonal/Annual/etc Graphs for his/her
local Weather.
Winner: All the entries this month are excellent and I've declared a 3 way
tie. I'm sending Ethernet
Demo Boards to all three contestents and one box also has an
SV-TEHS SX-DEV DEBUGGER. The
packages were shuffled so luck of the draw will decide who gets it.

John Coleman [jlsilicon at yahoo.com] has entered his
"ROV - Remote Operated Vehicle"
entry with game boy camera and motor controller circuits ready to add to
the Ethernet Demo board. His code looks ready to debug with the embedded
web server and will allow remote operation from any web browser! Just add
an 811.12 wireless ethernet adapter and John will have a true virtual presence
from the internet.
Winner: Ummm, with only one entry, who do you think won!

Timothy Stranex [perspex at dream.za.net] send along his "first ever
microcontroller project."
Digilight
It "...changes the intensity of 6 lamps using pwm, the pwm values are changed
through an rs232 port. The lamps could be coloured Red, Green and Blue and
create some nice colour sequences for discos (and for my imax-in-house project)."
Timothy hopes to expand this project into the Ethernet demo board
-
Guenther Daubach sent a very
nice "description and the source code for a
Morse code keyer using an
SX 28 device."
Guenther is obviously a pro and admits that he is writing a book on the SX
chips for publication later this year. I'll be looking to buy a copy when
it comes out if it has more projects like this on in it! He says he want
to win the debugger to give it to a student of his. Lucky guy.
Winner: Timothy Stranex. Tim has one
SV-TEHS SX DEBUG and an
SX Ethernet Demo on the
way.
