hello,

i am trying to generate music notes from the msp430.

i tried to aspects :

  1. using the buzzer and the PWM

  2. using the DAC12 making a sine wave and sending it to the 3.5mm jack (port 6.4) - didnt work …

i succseded 4 to do it with the buzzer but i want the sound\music notes to go to 3.5mm jack and from there to a set of speakers.

how can i do that ??? is it even possible ???

if not how can i do it with the DAC12 ?

thanks everybody.

The msp430 is not going to provide enough current to drive a speaker. Probably the easiest thing to get it working is to hook it up to some powered speakers like they have for MP3 players.

Have you tried using the [example software? In there is a voice recorder that uses the microphone and the audio jack. I would start there first.

The audio jack is connected to pin 6.5, not 6.4 so that may be part of your problem. Pin 6.4 is connected to the low-pass filter. Take a look at the [User Guide for your board to see what is connected to what and play around with the software to get familiar with the capabilities of the board.

HTH,
