We've added this forum so you can post about new and cool things in the world of mbed.

We're expecting info like:

  • Sharing a project you've just finished or found by point us to the cookbook/video/website etc
  • Showcasing an mbed-compatible baseboard or related product you've just made available
  • Highlighting upcoming events or workshops around or interesting to mbed
  • Other things that aren't really a question?

Hopefully it can be a little bit like a community blog. Each post should be a new thread, and then people can comment as they wish.

Hello Simon,

I want to use PWM to generate a frequenz for sound * numbers of form to put out sound direct via AlaogOut.

I have written sounds with Play_Note(float note, float lengh, bool combine, float loud, int instrument),

than I generate PWM with 1/note* number of points os form (so 47 to 58)

now I want to use PWM.read() to syncronice a FOR controll to read data of form to send there to analogOut(p18).

How can I be sure that on every rise of PWM I get a signal to start FOR?

I have tryed with IF (PWM.read() == 1) ... but it seems not running good. ist there annother way?
