How can I remove the crystal oscillator and use only the RC oscillator?

Hi Divebomb,
Thanks for your question. Please look at CFG_LP_CLK macro in da1458x_stack_config.h file. That macro should be set according to your requirement :
LP_CLK_XTAL32 : External XTAL32K oscillator
LP_CLK_RCX20 : Internal RCX clock
Thanks, PM_Dialog
Hi PM_Dialog,
Hi PM_Dialog,
Thank you for your reply.I want to remove all external crystal oscillators,I already know how to remove the external XTAL32K oscillator.How to remove the external XTAL32M oscillator?Can I replace it with RC32M oscillator?
Thanks & Regards.
Hi Divebomb,
The 32MHz crystal oscillator is required, as it provides the main system and BLE clock. The 32 kHz crystal is the low-power clock in sleep mode and is optional. When RCX is used, XTAL 32 kHz can be omitted.
I would recommend first checking theAN-B-075: DA14531 Hardware Guidelinesdocument.
Thanks, PM_Dialog
