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,
