It executed it's first program. Had a wiring error but it can be fixed with
 jumpers.

 The silver lever is a Aries zero insertion force socket for getting the
 chip
 in and
 out quickly for programming purposes. There is no on board in circuit
 programming
 for this version. You must have a stand alone programmer.

 It is not fully populated yet but all the other circuits have been tested
 on
 the bench.

 NICE !

 I am thinking of going one step up on processors to the 80C51.
 It is at least four times faster than the 8051. It has built in USB and
 PWM mode for the timers.

 BTW I am up in Monterey for the rotary races. Mazda owns the race track.
 We flew in to San Francisco which was a big mistake, You have to take a
 train to get a rental car. The people up here are logic and reason
 challenged. They could have built a big parking garage for the rental cars
 cheaper than the train. Total travel time was six hours. I could have
 driven it in 4 and the cost would be much much cheaper if you need to pay
 for airline tickets even with gas at $4 in CA. We don't as Robin is a
 retired UAL A&P.   The Comfort Inn has lousy Internet service. I am at
 Denny's.


My dad had a bad experience flying standby- he flew from Charlotte to
Chicago and was trying to get back. Took 2 days for him to get a seat.
Seems like Chicago might be a tad busy.

I have my board up and running too. I set it up with staged injectors and
manual leaning, all of which seem to be working correctly. I read MAP, temp
and RPM. I used a second board as a signal generator, and it worked well up
to 6000 rpm where the generated pulse width was short enough that it was
having trouble reaching the threshold voltage to fire the coils. I think
that I may have to use a second chip like the 555 as a trigger for the coil
to make sure it works at high rpm. At low rpm the CAS will trigger the
board, but didn't reliably fire the coils. It did fine at high speed.

It will be a bit before I can test it on the engine, I still have to fab
intake, install the radiators, etc. I did finally finish the left wing
except for installing the tip! Progress, little by little.
I will keep testing the code and the board and see how it holds up.

Paul, how many kb is your code file? Mine came in just under 10k total
uploaded to the board including the libraries for the digital temp chip.
The executed code is around 5k, the temp sensor I used has a built in ADC,
so it outputs the temp digitally.

Kevin, What AT chip number are you using? ZBASIC uses the AT1280 and the AT1281.
A lot of the problems with the timers are the same. Are you using software PWM?
I am moving much faster with ZBASIC than MikroBASIC and the 80x51xx.
Mainly because the help is in my time zone and not half way around the world :)
