I've been doing some more digging using Darrel Taylor's upgrade to the search engine: http://www.picbasic.co.uk/forum/showthread.php?t=4751
and found a nice description of another way to use A/D instead of ADCIN from Melanie that I am also going to try: http://www.picbasic.co.uk/forum/arch...php/t-352.html

I remember increasing the sample time to 100us before and maybe even more but it didn't make a difference. I'm sure if it's not configured right in the first place it wouldn't even matter! Man, am I glad that these devices are made to handle the all the flashing I can muster up.
One thing that's really bugging me, for lack of understanding, is that I have to keep the pot variable "Low_set" in the FOR/NEXT loop or else it won't give me the adjustable output. I thought that declaring Low_set = (ABS(low_adj-128))*8 once before going into the loop would be enough and that occasionally opening the door to let the flies in with ADCIN to update the variable "Low_set" would do the trick. BUT NOOO!!! I got the one read and it stayed fixed at that setting no matter how many flies I let in.

Code:
Low_Add_pulse:
    IF low_adj<=127 THEN GOTO Low_Trim_pulse ' Check pot position and go
    FOR x = 1 to 10                          ' Count to 10
       FOR i = 1 to 100                      ' Count to 100
            IF Sig1=1 then                   ' Input OFF then:
            PAUSEUS low_set                  ' Adjustable delay using pot
            LOW Inj1                         ' Turn OFF output
            ENDIF
            IF Sig1=0 THEN HIGH Inj1         ' Output ON if input ON
      NEXT i
            ADCIN 1, low_adj                 ' Check pot after a 100 loops
                                             ' for smooth adjustment
      NEXT x
      Low_set = (ABS(low_adj-128))*8         ' Declare every 1000 loops or
                                             ' adjustment not possible
            
GOTO Low_Add_pulse                           ' Do it again
I gotta believe that it's possible to do what I'm trying to do. The tired part of me says "just show me how to do it!" but the bigger part thanks you guys for the clues and direction so I can learn to be a confident PBP programming dude.

Thanks
