RE: R2D2 Sounds - A Warning my RCX has laryngitis.

The note duration must be a compile time constant. By any chance were you
trying to use a run-time variable (Robolab container) for this? This could
explain your problem.

Subject: R2D2 Sounds - A Warning my RCX has laryngitis.


I recently read a post from someone wanting to
generate friendy sounds similar to R2D2 using an RCX.
I thought this was a good challenge so set out to try.
 I was getting to the point where I could generate a
number of similar friendly sounds and then the RCX
stopped generating sounds completely (except for beeps
from the On-Off button when pressed).  This happened
within an hour!

I can only assume that the repeated intensive use of
the oscillator circuit has burnt out some component.
All other functions of the RCX seem to be intact.

Does anyone know the location of a circuit diagram for
the RCX?

The algorithm I was using (in Robolab) to generate the
sounds was as follows:

Select a start frequency.
