Can the nRF52 output the 32.768kHz clock on a GPIO. If so, do I need the 32.768kHz xtal, or can I output the generated clock from the 32MHz xtal? I need this clock to sync...
Hi
Yesterday I downloaded the new SDK12 and checked what changes could be relevant for my ongoing/next projects.
One remarkable thing was the fact that almost any peer...
