Definitely interested in an efis  with 16 analog inputs.   Was working on a more expensive version on my own, but this is less expensive, takes up less room, and better suited for the application. Don't mind having to do some work on it myself.  Looks like a glass dash  on the super rebel...

I'm very curious about this approach, too.  Did a bit of calling and
surfing today about it, too.  Looks as if the pic18c452 is the current
champ.  I know so little of these things, but I do know 6502 & 8086
family assembly language, C (my favorite), BASIC, and a few others.  I'm
a major software weenie.

Anyway, if anyone can help with these questions, please, or is there a
web site that can explain them (I've only searched over 100 sites so
far):

1. what can one do with the $99 or $159 "evaluation boards?"
2. how does one power these boards with 12vdc?
3. How does one store the PIC's program on the board?  Flash ram is my
favorite, but if it has eeprom or eprom with writers on the board,
that's ok, too.  Black lights are cheap 8-).
4. I've talked to Digikey, and MCM Electronics but their tech support
guys weren't much help.  Any other company sell these boards and
processors at equivalent prices that have techies that have a clue?
5. It looks like 'C' is available, but the only version I've found so
far is $495 -- there has to be a better way.  How much is the BASIC
compiler for it?
6. The chip has 33 i/o lines, but only 8 a/d lines according to the pdf
spec sheets.  However, other web sites say it has 16 a/d lines.  There
is also some discrepancy between web sites as to whether it is 8, 10,
12, or 16 bit a/d.  What is it really?

That's enough questions for now.  I'd like to order one or two soon.

Thanks,

Paul, why not approach  of Cicuit Cellar fame with the idea. This is right up his alley and would make a great article for his magazine to boot. In the process he would develope the code and there would be comprehensive instructions and a circuit board too. Microcontrollers, I/O and connecting to the real world are things he does a lot of, at the very least he might want to collaborate for an article.

Just another ho hum article for Steve Ciarcia's magazine. It needs to go out to the aviation
community through EAA Sport Aviation magazine.
