Using the uMP3 with the Prop-1

[JonnyMac]

Make sure that P14 is connected to the R input on the uMP3, and that P13 is connect to the T output.  Also, you should have common ground between the two boards.

I've always had good luck with the uMP3 and can't see why your program shouldn't work.

What do you mean by common ground between the two boards?   The black wire of the cable is conneced to the G on the uMP3 and to the B pin of P13.

Looks like I got it working.  The email I got with your post isn't showing up here?   You suggested using T9600 intead what you were doing in yours.  That did the trick.  It is working great now.  Now I just need to record a real speach, get the moving skull working, and program the head movements to the audio.  No problem.

Glad you got it working, Jeff.  I know how frustrating chasing gremlins can be.  I've spend the last week trying to make the SX48 behave nicely as a motor controller using its internal PWM generators -- it has been ugly at times.  Celebrate small victories as they always lead to larger ones.
