[LPC2124] A/D + PWM doubt - jadamezmartin - Jul 26 12:52:54 2006
Hello All,
I am working with the microcontroller (Philips LPC2124) and I need
to use the A/D and the PWM to generate audio. I mean, the audio
signal is going to be the input of the A/D and then I have to
"rebuild" it using PWM.
Has anyone done it? Is there something "special" to be considered?
Thanks in advance.

That shouldn't be much of a problem, depending on the sound quality.
Have a look at http://www.k9spud.com he did it on a LPC2103.
