| Hi Charlie
Think of a really fast TRS80 from back in the 80’s built into a single PIC32 chip but with great hardware control etc. The BASIC interpreter has commands to do a bunch of stuff really easily. It even supports interrupts and can do some quite good timing.
I took a photo just now of my 7” VGA LCD that will be going into my panel. Its running the code I attached. This code plots 10 analogue inputs across the bottom (all floating so reading various levels) Above the bar graph is a line graph which plots the analog #1 input in real time. You can see that in only a few lines of code you can plot and display various stuff. Download the MMBasic Language Manual - on Geoff’s web site - Downloads Documentation ….. I think there is a DOS port of the language available on the site so you could run the code up on a pc.
I plan to use it to: 1. Display position and status of my hydraulic retractables. 2. Run an auto trim system. 3. The audio out into my Dynon Skyview Audio for warnings.
Cheers

Price is definitely right, but I didn't
see any pre-packaged software. I can handle almost any hardware
construction, but I haven't programmed anything since before the
PC's designers were in middle school. :-) My limit is entering
configuration details. Is there display/logging software? If so,
I'd love to take a look.
Thanks,
Charlie

Hi Charlie
I’ve been around this loop for years. A tablet would be nice
but learning to program it is well beyond my time/ability
resources.
I'm using the “Colour Maximite”. Cheapish, 40 I/O with
Arduino shield support, VGA output to a 7”LCD display, basic
interpreter. Or use the Micromite which is setup to talk to say
a 4 line by 20 character LCD.
Simple hardware (you will need external amps for any
thermocouples, but doable), simple software. Good display
options.

I seem to remember some using
analog-to-digital converters and logging software to
monitor multiple sources of data (pressures, temps in/out,
etc).
I've quickly run out of 'inputs' on the EIS2000
engine monitor; I could use at least a dozen more for
various monitoring issues, at least for flight test.
Ideally, I'd like a multi-channel a/d converter that
could have inputs configured for typical resistive
sensors found on engines, and also J & k
thermocouples & new inexpensive pressure/temp
sensors like Tracy is using for manifold pressure and
inlet air temp. And software for a tablet, either
android or windows mobile.
This:
is obviously available at the right price :-), but
I'd prefer something already in a case with terminals,
and something that others have already vetted as
useful.
The EIS 2000 is so limited that if there's a usable
device with display software that's configurable (so
inputs can be named in the display), I'd seriously
consider abandoning the EIS for a tablet-based engine
monitor.
Any thoughts?
Thanks,
Charlie
Y'all come to the Pumpkin Drop. If you need to
overnight, we'll find a place for you.
