I can run peripheral examples in SDK folder like GPIO, Timer, Scheduler ... but when I want to Add somethings like GPIO to peripheral_UART_ble or timer or scheduler It didn't work well and timer or GPIO doesn't work at all.
this my code:
const nrf_drv_timer_t TIMER_LED = NRF_DRV_TIMER_INSTANCE(2);
and
void timer_led_event_handler(nrf_timer_event_t event_type, void* p_context)
{
static uint32_t i;
// uint32_t led_to_invert = (1 << leds_list[(i++) % LEDS_NUMBER]);
switch(event_type)
{
case NRF_TIMER_EVENT_COMPARE1:
printf("a\n");
break;
default:
//Do nothing.
break;
}
}
/**@brief Application main function.
*/
int main(void)
{
uint32_t err_code;
bool erase_bonds;
uint8_t start_string[] = START_STRING;
// Initialize.
APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_OP_QUEUE_SIZE, false);
uart_init();
buttons_leds_init(&erase_bonds);
ble_stack_init();
gap_params_init();
services_init();
advertising_init();
conn_params_init();
printf("%s",start_string);
err_code = ble_advertising_start(BLE_ADV_MODE_FAST);
// APP_ERROR_CHECK(err_code);
printf("%d",err_code);
uint32_t time_ms = 500; //Time(in miliseconds) between consecutive compare events.
uint32_t time_ticks;
err_code = NRF_SUCCESS;
err_code = nrf_drv_timer_init(&TIMER_LED, NULL, timer_led_event_handler);
printf("%d",err_code);
time_ticks = nrf_drv_timer_ms_to_ticks(&TIMER_LED, time_ms);
nrf_drv_timer_extended_compare(
&TIMER_LED, NRF_TIMER_CC_CHANNEL1, time_ticks, NRF_TIMER_SHORT_COMPARE1_CLEAR_MASK, true);
nrf_drv_timer_enable(&TIMER_LED);
// Enter main loop.
for (;;)
{
power_manage();
}
}
I only enabled Timer2 and I didn't enable Clock or anything else. But my program restart and printf("a\n") run very very fast.
I think
nrf_drv_timer_extended_compare(
&TIMER_LED, NRF_TIMER_CC_CHANNEL1, time_ticks, NRF_TIMER_SHORT_COMPARE1_CLEAR_MASK, true);
didn't effect
