Hello.
I am using nrf52832 and Segeer Embedded Studio.
I want to add a timer function to the ble_app_uart example so that the sensor value is read every 50 ms.
So I added the contents of the timer example to the ble_app_uart example.
ble_app_uart example : nRF5_SDK_15.3.0_59ac345\examples\ble_central\ble_app_uart_c\pca10040\s132\ses
timer example : nRF5_SDK_15.3.0_59ac345\examples\peripheral\timer\pca10040\blank\ses
There is no error when building.
And when I click the go button after debugging, there is no error.
However, if I click the break button to stop the program and then click the go button again, the program stops at NRF_BREAKPOINT_COND.
I don't know how to combine the timer in the ble_app_uart example.
I have seen comments that using Timer 0 may be a problem. So now I am using Timer1.
I would be grateful if you could help me with my problem.
The main.c code is attached.
int main(void)
{
uint32_t time_ms = 50; //Time(in miliseconds) between consecutive compare events.
uint32_t time_ticks;
uint32_t err_code = NRF_SUCCESS;
// Initialize.
log_init();
timer_init();
uart_init();
buttons_leds_init();
db_discovery_init();
power_management_init();
ble_stack_init();
gatt_init();
nus_c_init();
scan_init();
//GYR_Init();
//Configure TIMER for generating simple light effect - leds on board will invert his state one after the other.
nrf_drv_timer_config_t timer_cfg = NRF_DRV_TIMER_DEFAULT_CONFIG;
err_code = nrf_drv_timer_init(&TIMER, &timer_cfg, timer_led_event_handler);
APP_ERROR_CHECK(err_code);
time_ticks = nrf_drv_timer_ms_to_ticks(&TIMER, time_ms);
nrf_drv_timer_extended_compare(
&TIMER, NRF_TIMER_CC_CHANNEL0, time_ticks, NRF_TIMER_SHORT_COMPARE0_CLEAR_MASK, true);
nrf_drv_timer_enable(&TIMER);
// Start execution.
printf("BLE UART central example started.\r\n");
NRF_LOG_INFO("BLE UART central example started.");
scan_start();
// Enter main loop.
for (;;)
{
idle_state_handle();
}
}
