I feel like I'm way over my head here, but would it be possible to have

the 'setup'

of parameters done on a PC and downloaded to the unit which would then

simply scroll

up and down displaying 4 outputs and execute whatever alarm features are

included

according to the parameters present.  If you want to change something,

set up the

parameter list on a PC and download it to the unit.  Live with what

you've done for

that flight at the very least.  Cockpit unit would scroll and accept a

new parameter

list from the PC and that's about all.  Like a GPS that you could page

but not change

anything else on the fly.

snip

ive attached 6 files in pic basic that allows for changes on the fly
for the tbi unit that ive built.
the main file is afuel.bas there are 5 other files that are include files.
the total text file size is about 15k, compiled its about 1k.

it uses 1 rotary encoder with a mom contact push button built in
and a 2 line with 16 char display.

when pressed it goes to the beginning of the list
then it displays that item and the rotary then becomes a y/n toggle
you then push the button to "enter" the y or n
if its n it goes onto the next line option, if its a y the rotary allowes
you to scroll thru the options for that line, then the button is the enter
key for that option
and on it continues until you select end.

this is being used on a pic 16f876.

this is for a throttle body unit ive created for my kids volkswagon bus.

we havent installed it yet, but its completely assembled and appears to be
ready.

pic assembler norm?
