Subject: ARM EFI prototype

 I have ordered this ARM board to build a EFI system around, written in ARM
 compiled
 BASIC.

 It should be here in a few days DHL.

 We shall see how it goes.

 I should have something running in about a week.

 Paul,

 Could you give us the info on this board so we could consider buying one
 also.

 I am thinking of some developments to our robotics products.

 Here is the ARM board. It has infinite expansion potential.

 I am working on two systems. I am working on a parallel approach as well with
 a real simple and old CPU (8051 not a C8051) controlling mostly hardware.

 If you are interested in the simple system let me know. It will very limited but it
 is quicker to build and program I hope. I will be testing some of the hardware in a
 few days. I'll know then if it is going to work.

     Hey Paul,

     I was thinking about leaning on the way home tonight.  How about this.

     Put a rheostat/pot in the cockpit that adjusts a simple voltage divider
     so that the output can be varied across some arbitrary range.

     Connect said output to the A side of an A/D.

     Read the knob position from the D side of the A/D and use that as the
     multiplier for the pulse width generator.

     You wouldn't even have to use a high fidelity A/D.  Eight bits would be
     overkill for our purposes.  Set the knob in the center and use that as
     the base.  Higher is richer, lower is leaner.

     That is what I planned.

   They say that great minds think alike.  Do you have any idea where I can
   find one? ;-)

   One what Mark? http://www.mikroe.com/

 No, I meant a great mind.  Mine is pretty gummed up.  Sometimes I feel
 like one of those bigger and better idiots.

 "Programming today is a race between software engineers striving to
 build bigger and better idiot-proof programs, and the Universe trying to
 produce bigger and better idiots. So far, the Universe is winning." --

 or, as we say in the ship building industry,

 You can make it fool proof, but you can't make it sailor proof.

 Oh man, I should have put this on the National Budget email chain.

 Sounds like you live in the Norfolk area :)

Newport News

They don't build any ships in Norfolk.

All commercial ship building in the world today is subsidized by their
governments.  The U.S. decided that supporting shipbuilding jobs was not
where they wanted to spend their money.  I think that was a good ethical
decision.

Too bad they don't feel the same way about the auto industry.  If they
did we wouldn't have "government motors" unfair competition today.  I
hear that Fiat is pulling their support for NASCAR at the end of this
year's season.  Next year it will be Ford, Government Motors, and
Toyota.  The Sahlen's ALMS team is dumping Mazda now that they quit
supporting the RX8 rotary.
