Hi all,
I am developed application so that it is communicate with save device, i can able to send data from master to slave. In Ble_app_multilink_central master side code, if i use rtc, master is not connecting to slave. If i comment Rtc part i can able to communicate with slave device. I am using s120_nrf51822_1.0.0_softdevice for master code.
here is my RTC code:
static void lfclk_config(void)
{
NRF_CLOCK->LFCLKSRC = (CLOCK_LFCLKSRC_SRC_Xtal << CLOCK_LFCLKSRC_SRC_Pos);
NRF_CLOCK->EVENTS_LFCLKSTARTED = 0;
NRF_CLOCK->TASKS_LFCLKSTART = 1;
while (NRF_CLOCK->EVENTS_LFCLKSTARTED == 0)
{
//Do nothing.
}
NRF_CLOCK->EVENTS_LFCLKSTARTED = 0;
}
/** @brief Function for configuring the RTC with TICK to 100Hz and COMPARE0 to 10 sec. */ static void rtc_config(void) { NVIC_EnableIRQ(RTC0_IRQn); // Enable Interrupt for the RTC in the core. NRF_RTC0->PRESCALER = COUNTER_PRESCALER; // Set prescaler to a TICK of RTC_FREQUENCY. NRF_RTC0->CC[0] = COMPARE_COUNTERTIME * RTC_FREQUENCY; // Compare0 after approx COMPARE_COUNTERTIME seconds.
// Enable COMPARE0 event and COMPARE0 interrupt:
NRF_RTC0->EVTENSET = RTC_EVTENSET_COMPARE0_Msk;
NRF_RTC0->INTENSET = RTC_INTENSET_COMPARE0_Msk;
}
/** @brief: Function for handling the RTC0 interrupts.
-
Triggered on TICK and COMPARE0 match. */ void RTC0_IRQHandler() {
if ((NRF_RTC0->EVENTS_COMPARE[0] != 0) && ((NRF_RTC0->INTENSET & RTC_INTENSET_COMPARE0_Msk) != 0)) { NRF_RTC0->EVENTS_COMPARE[0] = 0; NRF_RTC0->CC[0] = NRF_RTC0->CC[0]+(COMPARE_COUNTERTIME * RTC_FREQUENCY); // nrf_gpio_pin_toggle(GPIO_TOGGLE_COMPARE_EVENT); } }
If i add this code into central code and debugged the code, at that time it is going to this part.
HardFault_Handler
PROC
EXPORT HardFault_Handler [WEAK]
B .
ENDP
Can any one please help me on this why it is behaving like this.
Regards Manjunath
