NRF52832 clock driver for SDK 15.2.0

1.在sdk_config.h加入宏

#ifndef UART_DEFAULT_CONFIG_IRQ_PRIORITY #define UART_DEFAULT_CONFIG_IRQ_PRIORITY 6 #endif

#ifndef NRF_CLOCK_ENABLED #define NRF_CLOCK_ENABLED 1 #endif

#ifndef NRFX_CLOCK_CONFIG_IRQ_PRIORITY #define NRFX_CLOCK_CONFIG_IRQ_PRIORITY 6 #endif

#ifndef NRFX_CLOCK_CONFIG_LF_SRC #define NRFX_CLOCK_CONFIG_LF_SRC 1 #endif 2.导入nrf_drv_clock.c和nrfx_clock.c文件到工程

3.初时化       if(!nrf_drv_clock_init_check())       {            APP_ERROR_CHECK(nrf_drv_clock_init());               printf("\nnrf_drv_clock_init\n");       }

4.请求低频时钟

 nrf_drv_clock_lfclk_request(NULL);       nrf_delay_ms(100);        if(nrf_drv_clock_lfclk_is_running())       {             printf("nrf_drv_clock_lfclk_is_running\n");       }

6.释放低频时钟

 nrf_drv_clock_lfclk_release();       nrf_delay_ms(100);        if(!nrf_drv_clock_lfclk_is_running())       {             printf("nrf_drv_clock_lfclk_is_stop\n");       }

7.请求高频时钟

nrf_drv_clock_hfclk_request(NULL);              nrf_delay_ms(100);        if(nrf_drv_clock_hfclk_is_running())       {             printf("nrf_drv_clock_hfclk_is_running\n");       }

8.释放高频时钟

 nrf_drv_clock_hfclk_release();       nrf_delay_ms(100);        if(!nrf_drv_clock_hfclk_is_running())       {             printf("nrf_drv_clock_hfclk_is_stop\n");       }
