Hi,
I'd want to implement RTC for regular testing of a variable. I am largely based on The BLE_uart exemple and have added a timer instance and a PWM instance. As the variable I want to check come about every second or more, I wanted to use the RTC librarr for low power consumption.
#include "nrf_drv_rtc.h"
#include "nrf_drv_clock.h"
const nrf_drv_rtc_t rtc = NRF_DRV_RTC_INSTANCE(1);
/** @brief: Function for handling the RTC0 interrupts.
* Triggered on TICK and COMPARE0 match.
*/
static void rtc_handler(nrf_drv_rtc_int_type_t int_type)
{
if (int_type == NRF_DRV_RTC_INT_COMPARE0)
{
NRF_LOG_INFO("COMPARE");
}
else if (int_type == NRF_DRV_RTC_INT_TICK)
{
NRF_LOG_INFO("TICK");
}
}
/** @brief Function starting the internal LFCLK XTAL oscillator.
*/
static void lfclk_config(void)
{
ret_code_t err_code = nrf_drv_clock_init();
APP_ERROR_CHECK(err_code);
nrf_drv_clock_lfclk_request(NULL);
}
/** @brief Function initialization and configuration of RTC driver instance.
*/
static void rtc_config(void)
{
uint32_t err_code;
//Initialize RTC instance
nrf_drv_rtc_config_t config = NRF_DRV_RTC_DEFAULT_CONFIG;
config.prescaler = 4095;
err_code = nrf_drv_rtc_init(&rtc, &config, rtc_handler);
APP_ERROR_CHECK(err_code);
//Enable tick event & interrupt
nrf_drv_rtc_tick_enable(&rtc,true);
//Set compare channel to trigger interrupt after COMPARE_COUNTERTIME seconds
err_code = nrf_drv_rtc_cc_set(&rtc, 0, COMPARE_COUNTERTIME * 8,true);
APP_ERROR_CHECK(err_code);
//Power on RTC instance
nrf_drv_rtc_enable(&rtc);
}
void rtc_init()
{
lfclk_config();
rtc_config();
}
I have this error message :
multiple definition of `RTC1_IRQHandler'; \components\libraries\timer/drv_rtc.c:353: first defined here
I'd like to know if I need some configuration or if I could and how to create custom event based on pin input (softdevice based event).
Best Regards,
Charles
