What's a Tablet PC?
Tablet PCs are compact, ultra-portable entertainment devices that
let you read email, surf the Internet, read eBooks, view photos,
play games, listen to music and watch video files. Most tablets are
based on a smaller operating system, which allows you to purchase
and download additional applications from supported stores. Tablet
PCs do not have a CD/DVD drive and will not run Microsoft Windows
or its applications. Tablet PCs function as a secondary device for
casual entertainment purposes, and are not meant to replace a
computer. They are ideal for use around the home and on the go with
WiFi or 3-4g mobile broadband connections (pay as you go, contract
may be required for service).
In theory the ARM BASIC EFI can use this as an EFIS display for all
you engine parameters.
No stand alone LCD for micro EFI computers can come close to this
resolution.
Things they are a changing fast :)

Has anyone looked at the Raspberry pi or Beaglebone Black with a
high NIT display on the HDMI port? Seems like perhaps a good EFIS
core. Has SD slot, USB, HDMI, network, uart port, some gpio, etc...
Certainly missing the 4.3" touchscreen at $50.
Dunno what happened here as pi's keep replicating at my home. They
shoulda called it the Tribble device.

The cost of the ARM IDE software (Integrated Development
Environment) is $3,300 to $6,600. They must be kidding :)

ARM IDE's are free from Coridium.

Hi folkz
I was a businesses devloper at a Wankel engineering-facility and be a
pilot of ultralights.
For my gyro-project I will relay on mazda rotary and hook on the
analogue world to my tablet with IOIO. An Arduino shield can also due
the job.

Maybe it will speed up our dreams for an EFIS tablet ;-)
My biggest concerns are the bad looking displays in sunlight or
coldness...
kind regards Claude
Sometimes you have to make a shroud or hood.
IMHO BASIC on 32 bit Teensey 3.1 beats Arduino by a factor of two :)

IMHO C is cryptic nonsense. Computers are smart.
They should be able to understand plain English.
BASIC is the closest thing to plain English in the
computer programming world.
As far as I can tell there is no BASIC IDE for Raspberry.
There appears to be some Linux solutions but most
of the world users have Windows unfortunately.
Paul Lamar
Have no interest in an EFIS on a tablet as there are many many
commercially successful solutions that are tested and affordable.
No need to re-reinvent the wheel.
Much interest in simplified EFI and ignition systems that work on
real engines. Current commercial solutions are expensive and complicated.

If you would like to practice while I get the low cost EFI printed
circuit boards made
down load the free qb64. I think it runs on Windows 8. There is no hardware
I/O like PWM or A to D in qb64 but you can practice arrays which are the
key to any EFI.
Windows, unlike the old DOS, does not allow hardware I/O.

When I get the EFI PC board done you will need a $29+ $9 shipping Mini
MO from this company.
It is the brains of the EFI and allows the EFI to communicate with your
PC using a USB cable.
There will be a socket on my EFI PC boards that this plugs into. I have
done biz with this
company in the past and they are reliable.

Once you have that you can download the free BASIC from them that does do
hardware I/O. No need for my PC board yet. You can turn LED's on and off
to simulate
injectors and feed low voltages up to 3.3 volts into the A to D and see
what affect that
has.
A scrap MAF would be fun to play with as you can use a hair dryer to make it
think it is seeing intake air flow. Don't forget to limit the MAF out
put voltage with
a divider and 3.3 V zener. The Mini MO can send the voltage out of the
MAF to
your computer screen. Good testing device for MAF's.
You can also build a smart rotary engine compression tester with the
Mini MO.
All you need is a $5 pressure sensor from DigiKey or Mouser.
Testing various other engine sensors (water temp, oil pressure, manifold
pressure, etc., etc., etc..) is a piece of cake. But you probably have
all that stuff
already at work.
I should be getting my Mini MO any day now.
