Before you start taking apart your furniture, you
might look first at HomeDepot or Orchard supply or
just a hardware store, or auto parts store. They have
springs of different sizes, compression or extension.

I'm guessing that you're in the USA.

Hola Francisco Betzaeth Rangel Martinez or Paco:

You mean that you would like to know how to interface

parnslayer

I haven't worked with that model(and very little with GPS), but for general
troubleshooting -
Obvious: Have you checked the antenna?
Are you inside, or does your neighborhood have a lot of metal surfaces in it?
(you could be getting reflected signals that screw up the timing. 10 satellites
seems pretty high to me, from what I remember)

I am assuming you have not gotten Longitude yet - I recommend changing over to
that, and seeing if you have the same sort of jumping around.
Are you sure you have the format right? Is it DDMMSS.SS, DDMM.MMMM or DD.DDDDDD?

Hi everyone,

I was putting together the programming cable part of the Level 1 Kit
(http://seattlerobotics.org/WorkshopRobot/level1/index.php), and messed
up on it very badly.  Rather than trying to fix it, I'm considering just
buying another cable.  I was wondering, though -- is there any place
where I can purchase an already assembled programming cable that
connects to the CPU via a DB-25 parallel port?  Or if not, can someone
please tell me the names of the various parts needed to make another
programing cable?

Thanks,
Any help is greatly appreciated!

I don't know if this will help, but I recently purchased a programmed pic on
ebay, something like "GPS decoder", that will take the raw NMEA stream of data
and convert it into a short more useable string of data.  If came from china. 
That may be something to look into for ease of use.

The programming header of the Workshop Robot is a standard AVR 10 pin ISP
header.  Any ISP programmer will do.  You can get simple DB25 programmers
from www.olimex.com, www.sparkfun.com and many other places.  A proper ISP
programmer that runs off a usb port, or serial port is worth the extra $30
(they cost ~$50) and are available from most distributors (digikey).

No, you want the programmer for the AVR, not the TI MSP chip.

should do.

Sparkfun sells Olimex stuff.  Try Olimex as well, although the product,
listed above, is probably Olimex as well.

On a separate note I believe I have learned that the 2x5 header has
been deprectated by ATMEL in favor of the 2x3 (ATMEL AVR910

I haven't cross-referenced the pins yet but it would be handy to be
able to use the ARVISP mkII with the ARC board.

If I am not mistaken the MSP-430 has a different programming ISP than an AVR
one.  You can get one from wrighthobbies.com for cheap.  I have a few and
they work good.  I think he sells them assembled as well.

Oh okay, thanks.
www.sparkfun.com had one, but they were sold out.
I did manage to find this one, though:

What a bout a pogo stck spring.  There are a few with exposed springs and

Mark,

Use the -F to ignore the signature.  From what I understand signature
verification does not work with the Windows of AVRDUDE version.  I have
always had to add -F option to all of my make files.  Perhaps Argued has
been fixed and included in the latest WinAVR 20070122.

Subject: Stellaris Cortex M3 .. GCC / Codesourcery questions

johnmciv

I know some folks here have the demo board for the lm3s811.  I have
questions ...

It seems like all the demo examples reference the driver library, that
is specific for the demo board, but none reference the libraries in
the main Codesourcery path.  I have not been able to figure out 1) why
no functions from these main libraries were used in the demo programs,
and 2) when I try to access them I get a bunch of messages like this ...

writer.c:(.text+0x12): undefined reference to `_write'
d:/program files/codesourcery/sourcery
g++/bin/../lib/gcc/arm-none-eabi/4.1.1/..
/../../../arm-none-eabi/lib/thumb/thumb2\libc.a(closer.o): In function
`_close_r
':

3) there seems to be alot of libraries under the "arm-none-eabi" level
for lib/ lib/thumb /lib/thumb/thumb2/ and another set here
/lib/gcc/arm-none-eabi... , is this processor able to handle only one
of these library types (seems to want to point to the thumb2
libraries)? I am a little unclear about the "thumb" modes, is there a
simple explanation? Does it have to do with memory addressing?

4) Here's what I have managed to do ..

Get the GCC toolchain working, and compile all the examples that were
ported over from the Kiel tools.

Write a function to convert a unsigned long to a string, so I can
print a numeric value to the matrix display.  I did this, because I
couldn't manage to get a libray function .. sprintf to load, all I did
was add...  #include "stdlib.h"  to my code, is this not enough?

Could anyone offer a very simple example of accessing these libraries,
include please a code snippet, and a makefile snippet, if you have the
answer.

Super big thanks !   ...John

Probably just trying to keep the code portable?

The ARM processor has a few different flavours. There's the 32-bit
instruction set, the thumb instruction set and the thumb2 instruction
set. The CodeSourcery compiler can deal with all of these variants.
The LM3S811 is a thumb2 only variant.

I think that the problem relates to how the libraries are compiled and
linked. I think that there are some issues with the new "garbage
collection" scheme being employed by the linker.

It used to be that a runtime library would have a separate object file
for each function. The "new" way is to use fewer object files and
allow the linker to be cut out unused functions. Unfortunately, it
still seems to require the unneeded functions so that it can cut them
out (go figure).

The runtime library that comes with code sourcery is missing a few key
functions, which need to be implemented by the OS, and since there is
no OS, it falls on the developer to implement them (I've run into this
in the past).

The libraries which are under /lib/gcc contain functions which are
considered to be compiler suppoprt functions, as opposed to the other
stuff under /lib, which is considered to be runtime library support
functions.

I have a pretty nice StrPrintf function which you can find on my svn server:
<http://websvn.hylands.org/listing.php?repname=Projects&path=%2Fcommon%2F&rev=0&\
sc=0>
You'll need Str.h and StrPrintf.c

There should be enough documentation in the source file to understand
how to use it.

I've also put together a few little programs of my own:
<http://websvn.hylands.org/listing.php?repname=Projects&path=%2Fluminary%2F&rev=\
0&sc=0>

If you like, you can retrieve my entire svn tree using the following:

svn co svn.hylands.org projects

This will place all of the source files into a directory called
projects (you can use any name you like). In theory, you should be
able to cd into luminary/PWM-Test and type make and it should build.
If you run into troubles, let me know.

Hey Guys!
I bought a Pololu dual serial motor controller and it has gone
haywire after a couple of uses. When I apply 9v to the supply input I
am reading this 9v across serial input, motor1 output and motor 2
output. Seems like I burnt an IC. The Pololu device is now sending
current to my robot without recieving a line signal from my
microcontroller.
How durable are these Pololu dual serial motor controllers?

It's been suggested to me that Junun might be a small business, and as
such the owner might be sick, or away and that might be the reason why
he's not responding.  Does anyone know whether Tim is okay, or out of
