Hello!

The following is a snip of a PicBasic program which reads 2 A/D channels
(LTC1298) and is suppose to display them independently on a bargraph. The
problem is when I call  for the "test_zero" display,  the bargraph will read
either both A/D channels. They are not isolated. When I get the channel 0 A/D
value I copy it
to the "test_zero" register. When I get the channel 1 A/D value I copy it to
the "test_one" register. When I attempt to display channel 1, channel 0 will
also display. I only want to display one A/D result at a time.

Do I need a delay before getting the next channel?
The AD register is 16bit. I only need to display 8 bit so I wrote let
test_zero = AD/16, where test_zero is a 8 bit register. Can I do that?

I am sure I am missing something simple. Please have a
looksee. I have a code snip to not bore you with other details.

main:
  gosub  GetAD                  ' Get test0 amd test1 A/D sample
  gosub  show                   ' Display fuel sample on bargraph
  goto main

show:
  let dispVal=test_zero/32      '8 bit result
  lookup dispVal,(64,96,112,120,124,126,127,255),bargraph
  gosub MaxDisplay
  return

GetAD:
  let ADch = 0                  ' Toggle between input channels.
  gosub Convert                 ' Get data from ADC.
  let test_zero = AD/16                 '  AD to 8 bit 0-255  and store AD resul
t

  let ADch = 1                   ' Change input channels.
  gosub Convert                 ' Get data from ADC.
  let test_one = AD/16          ' AD to 8 bit 0-255  and store AD result
return
