In TiyoYuden EYSHJNZWZ, how to use the internal RC Oscillator

[Shingen Miyamura]

I am using the original board. It does not have a 32kHz crystal.

So I want to use the built-in RC oscillator.

In addition, use the time example of nRF5_SDK_16.0.0.

"NRFX_CLOCK_CONFIG_LF_SRC 1-> 0" is selected

I wrote other RC oscillator options, but they don't work.

Please tell me how to use the built-in RC oscillator in TiyoYuden EYSHJNZWZ.

Hi

This snippet should not be added to the sdk_config.h file. You should add it to your main.c file, for example in a clock_initialization(); function like what is done in the BSP example. What do you mean by "the first description"?

Best regards,

Simon

Dear Simonr.

>> You need to add it to the main.c file (example　in clock_initialization ();).

Should it be written as a function in the initialization process of main.c?
Is the content of the function exactly the same as the snippet?


>> What does "first explanation" mean?

It is the following content that you answered first.

NRF_CLOCK-> LFCLKSRC = (CLOCK_LFCLKSRC_SRC_RC << CLOCK_LFCLKSRC_SRC_Pos);
NRF_CLOCK-> EVENTS_LFCLKSTARTED = 0;
NRF_CLOCK-> TASKS_LFCLKSTART = 1;

while (NRF_CLOCK-> EVENTS_LFCLKSTARTED == 0)
{
    // Do nothing.


Thanking you in advance
