nrf 52832 SAADC without timer

[AKV]

hello i am beginner in this,i am using example\ peripherals\ saadc for nrf 52832.  This example code is done by using timer and i could not understand how to use timer. We need converted data direct from register without timer.

To work with the API without timer, you do a

nrf_drv_saadc_sample_convert(0, &adc_buf);

sorry, i am beginner in this please provide example code or more details about this.

Something like this. This is based on SDK 13. For SDK 15, replace nrf_drv_ with nrfx_

#include "nrf_drv_saadc.h"

void saadc_event_handler(nrf_drv_saadc_evt_t const * p_event) {
	// Do nothing, as we use blocking mode
}

int saadc_init() {
  int ret = nrf_drv_saadc_init(NULL, saadc_event_handler);
  if (ret) return ret;
  nrf_saadc_channel_config_t config =
		NRF_DRV_SAADC_DEFAULT_CHANNEL_CONFIG_SE(NRF_SAADC_INPUT_AIN3);
  ret = nrf_drv_saadc_channel_init(0, &config);
  return ret;
}

int saadc_measure() {
  nrf_saadc_value_t value;
  nrf_drv_saadc_sample_convert(0, &value);
  return value;
}

int main() {
  saadc_init();
  int measurement = saadc_measure();
}
