Hardware External 32kHz XTAL detection

[Bruno Deguet]

Hi all,

Is there a software way to detect if an external 32kHz XTAL is connected to the nRF52 or not ?

So it could possible to select the internal RC oscillator instead of the external source by calling nrf_clock_lf_src_set() with the appropriate value during the init phase.

Thanks for your answers,

My configuration : nRF52832, SDK v12.3.0

Hi,

 

Unfortunately, there is no option to detect if there's a 32k xtal present on the XL1/XL2 pins.

 

Best regards,

Håkon
