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 florin! I need a 32k clock for MAX30003 bio medical sensor too! But i'm measuring only 16.38Khz with the above code.Did you get a 32K signal from the above code? and how did you share the 32k signal from the crystal? It was a hardware sharing or a software sharing? Thank You!

Hardware. I patched a wire from the crystal to the other chip.
