Using MSP430 to drive PWM audio

While this should in theory work, and I believe customers have done this with the MSP430, we do not have any information on how to interface the MSP430 to our audio devices. If this is something that would interest you, please reply to this post so we can judge the interest out there for such an app note.

  • Hi,

    I definitely need to get a 4kHz PWM signal on a pin which will sound a buzzer/alarm. I'm using MSP430f6723.

    I'm searching the other solutions, but the rates that are being used are much, much lower.

    Thanks

    Hi, Mechi,

    There are a couple app notes out there describing how to do audio on the MSP430. If you can't find them, I suggest you post a new thread in the MSP430 forum.

  • Hey there!

    My design group and I are definitely interested in interfacing the MSP430 with audio devices. We were working with the Audiosink to begin with which was all to easy to connect to but for our project we needed a means to create control voltages to connect to analog circuitry and also store wavetables to create a type of digital synthesis and output them through the MSP430 directly. So far we can play a few nice, short coded jingles but we are still working on having incoming data to change our microcontroller output voltages.
