[time2dive]

I am trying to control a MDFLY AU5018 it wants a low to control what plays it runs on TTL voltage inputs. As of now I am using the Prop 1 to control 5v relays P0-P5 to control "Play", "Repeat" and "Tracks. I am using a push button trigger which does appear to work
The problem that I am having is that only the relay hooked up to P0 is doing anything. It is triggering when the other I/O (P1-P5)should be triggering. The other relays have power.

here is my code

Hi Tim,

I made a few updates:

- Added pin definitions in the Initialization section.  You forgot these, they're important on the BS1.
- Added "PIN" to PIN5 - you needed this.
- Changed all HIGH and LOW lines to JM's "IsOn" and "IsOff", which is easier to read.  You already had that set up in the top of the code.
- Your pauses were all very short, I made them longer so you can see them.  Remember that PAUSE = 1000 is only one second long, so 250 is really short and may not be what you wanted.
- Added JM's debounce routine for the button input.  This will also work for a PIR.  Doing it this way makes things more reliable, especially with a PIR.
- Some simple reformatting, including labelling your first section "Startup" because you're doing something different there than when you trigger the prop.

I tested this on a Prop-1 Trainer.  Try it out, and I think you'll want to experiment with the pauses, they're still pretty short.

Pin0-Pin4 are using P0-P4 using servo connectors,  the light is using Out5. Should that be labeled Out5 or just 5. The reason for the 250 msec pauses is to simulate pressing a button on the audio board.
I will make changes and try it.

[Jeff Haas]

If you're  using relays for all the outputs then I thnik the program will work the way it is.  Using the screw terminal for the light is usually a way to have the Prop-1 provide the power, but triggering the output is the same.

Let us know how it works out!

[time2dive]

Everything works! Thanks for the help. So the main changes were to replace  "High Play" with "play IsOn" and all of the other similar commands and add the trigger function....so I was sort of close.  I will tweak the pause and play times to fit the actual track time and see if the Prop1 will control the MDFLY board without the relays.
Will this same code work for a Prop2? I will need more outputs for the final prop. This was a test of concept.
Again...thanks for the help.

[Jeff Haas]

A really important change was the two lines in the initialization section, which configure the pins.

This will need to be adapted for the Prop-2, some of the Basic commands are different.

Tim,

One thing I forgot - the MDFly board you're using can be controlled by a serial connection with a Prop-2.  The Prop-1 doesn't have the right serial speed to work with that board, but the Prop-2 can work fine with it.  So it will make things easier to control the sound effects - you have one connection from the Prop-2 to the MDFly board.  I've got a few of these modules and have used them very successfully with the Prop-2.  I will put up a thread in the Prop-2 section and post code there for you.
