Generate 32768 hz signal on a GPIO

[Florin]

Hi,

Sorry for the noob question: I would like to generate a signal on a GPIO pin that beats at exactly at 32768 Hz. Is it possible to use the RTC having prescaler set to 0 and CC set to 1?

Thank you! florin

Hi Yashur, I used initially the code in the link above. I actually needed the signal for the Si4703 FM receiver and the signal provided via the GPIO although was oscillating correctly I suppose, introduced so much noise that it made tuning impossible. In the end I shared the 32k signal from the crystal and it worked perfectly.
