Hi ,
I need to generate a count data to third party library.
So I create a timer1 ,it can work well.
But I set time_us equal to 1 ,the "timer_led_event_handler" don't work.
Could I set time_us = 1 ?
below is my code,
uint64_t timer_data=0; void timer_led_event_handler(nrf_timer_event_t event_type, void* p_context) { switch (event_type) { case NRF_TIMER_EVENT_COMPARE0: timer_data++; break; default: //Do nothing. break; } } void timer1_init() { uint32_t time_us = 1; uint32_t time_ticks; uint32_t err_code = NRF_SUCCESS; //Configure TIMER_LED 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; timer_cfg.bit_width = NRF_TIMER_BIT_WIDTH_32; err_code = nrf_drv_timer_init(&TIMER_LED, &timer_cfg, timer_led_event_handler); APP_ERROR_CHECK(err_code); time_ticks = nrf_drv_timer_us_to_ticks(&TIMER_LED, time_us); nrf_drv_timer_extended_compare( &TIMER_LED, NRF_TIMER_CC_CHANNEL0, time_ticks, NRF_TIMER_SHORT_COMPARE0_CLEAR_MASK, true); nrf_drv_timer_enable(&TIMER_LED); }
