more prop 1 questions

[djm902]

I have been working with the prop for a little bit now tweaking the programming to get it the way I like it,
but the other day I got it adjusted just right but now I can't seem to get it to trigger.
I am using pin 6 for the trigger and it is in the down postion
please help
thanks

I'm a great programmer, not such a great mind reader!    ;D

Please post you code so I can have a look.  Also, tell me what you're using as a trigger device.

  CapAudio = IsOff

  Solenoid = IsOn
  PAUSE 1000
  Solenoid = IsOff
  PAUSE 120000
  GOTO Main

thats the code you made for me  awhile ago just slightly adjusted.
I am using a connector with  two wires coming out of pin 6. white and red.

The only problem I see in the code is:

  PAUSE 120000

... this is not possible as the maximum value in the Prop-1/2 is 65535; you need to break it into two statements:

  PAUSE 60000
  PAUSE 60000

For triggering you should be able to use a N.O. (normally open) button or switch connected between P6.W and P6.R.

[djm902]

ok I did what you said and adjusted the pause time from 120000 to 60000 x2.
It seems to be triggering now but out 0 is not working at all ,and this is what triggers my audio

[JonnyMac]

There's no reason it shouldn't work -- you could have a bad ULN.  Your program is compatible with the Prop-1 Trainer; have you tried that to see if P0 and P1 LEDs light?

[livinlowe]

Where are you connecting Out 0 to? One wire should be in Out0 and the other should go to V+ on the green connectors. The ULN sinks current, it doesn't supply current. (i.e. it acts as a ground not a voltage source)
