Hi,
I am trying to make a micro second timer count and I am using the timer driver from the timer example. However the timer init is failing in my code and I am not sure why. Here is my code:
uint32_t hrt_time_us = 0;
const nrf_drv_timer_t HRT_TIMER_INSTANCE = NRF_DRV_TIMER_INSTANCE(0);
void hrt_timer_event_handler(nrf_timer_event_t event_type, void* p_context)
{
switch (event_type)
{
case NRF_TIMER_EVENT_COMPARE0:
hrt_time_us++;
break;
default:
//Do nothing.
break;
}
}
void hrt_timer_init()
{
uint32_t time_us = 1;
nrf_drv_timer_config_t hrt_timer = NRF_DRV_TIMER_DEFAULT_CONFIG;
NRF_LOG_INFO("init hrt");
err_code = nrf_drv_timer_init(&HRT_TIMER_INSTANCE, &hrt_timer, hrt_timer_event_handler);
APP_ERROR_CHECK(err_code);
uint32_t time_ticks = nrf_drv_timer_us_to_ticks(&HRT_TIMER_INSTANCE, time_us);
NRF_LOG_INFO("ticks: %d", time_ticks);
nrf_drv_timer_extended_compare(&HRT_TIMER_INSTANCE,
NRF_TIMER_CC_CHANNEL0,
time_ticks,
NRF_TIMER_SHORT_COMPARE0_CLEAR_MASK,
true);
nrf_drv_timer_enable(&HRT_TIMER_INSTANCE);
I have TIMER_ENABLED set to 1, TIMER0_ENABLED set to 1.
The nrf_drv_timer_init function fails. Any inputs on why this may be happening?
