Hi Joe, About question 3, do you have any idea of how to play a *.wav audio file on Tmote Sky?
Thanks!

You need to use a sine wave with less samples per period to get higher frequencies. > 2. Does the DMA.setupTransfer command set up transfer once? How does > TimerExclusive control repeating DMA transfer? It sets up the DMA with the specifications/parameters. Timer keeps running until you tell it to stop. Please see the MSP430 User's Guide, these questions and more are answered by this document. > 3.

No, no such component exists. -Joe _______________________________________________ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
