LFCLKSTAT status

[yu-wang]

I want to read the status of LFCLK,but I find that ,the value I have readed is awayls zero! my code is follow : LFCLK_State = ((NRF_CLOCK->LFCLKSTAT) >> 16) & 0x00000001; printf("LFCLK_State:%u\r\n",LFCLK_State);

   Is there any mistake here?

thanks and best regards

Yes I have faced similar problem. There is a wait time before register will be updated.

Please add some - for example nrf_delay_ms(2) before reading register status.

I guess you have following problem:

1. reset
2. starting LFCLK
3. read status == not running.

I proposed 2 ms between points 2 and 3 and it shall be far enough. Basically I believe you can change it to nrf_delay_us(30) or even less. You need to test it.
