Hello Marc is there is any possible way to make a phone ring by pressign the button on the NRF51dk if so could you suggest me the ideas behind in it?

Do bear in mind that you'll be limited to clk/2 in terms of frequency (Nyquist's theorem).

But, unless you're a teenager, that shouldn't be a major problem :)

Thanks Hakon,

I didn't think of that before, but I think your solution is much better than the one I came up with

Hi Mark,

Since you are going to play basic sounds, like beeps, you could use a timer to generate a PWM output.

Best regards Håkon
