How to get every adc channel conversion result?

[chenyu]

Hi: I want use all eight ADC channel, But I don't know how to get different channel conversion result.

I write my code as follow:

void adc_config(void)

{ const nrf_adc_config_t nrf_adc_config = { ADC_CONFIG_RES_10bit, NRF_ADC_CONFIG_SCALING_INPUT_ONE_THIRD,
NRF_ADC_CONFIG_REF_VBG };

nrf_adc_configure( (nrf_adc_config_t *)&nrf_adc_config);
nrf_adc_int_enable(ADC_INTENSET_END_Enabled << ADC_INTENSET_END_Pos);
NVIC_SetPriority(ADC_IRQn, NRF_APP_PRIORITY_HIGH);
NVIC_EnableIRQ(ADC_IRQn);

}

void ADC_IRQHandler(void)

{

nrf_adc_conversion_event_clean();
adc_sample = nrf_adc_result_get();
nrf_adc_start();

}

In my main funciton I do like this:

nrf_adc_input_select(NRF_ADC_CONFIG_INPUT_2);
		printf("%d",adc_sample);
nrf_adc_input_select(NRF_ADC_CONFIG_INPUT_3);
		printf("%d",adc_sample);

.... Now, I wonder that : 1.if this funciton is right ? 2.can I get adc result without ADC_Interrput? thank you!

1. Probably not although you're not showing the entire code. You need to first input_select, then adc_start and then wait for the interrupt to get the result. Then select another channel, start conversion, wait for interrupt... You can't select every channel at once.

2. You can use nrf_adc_convert_single to get results from each channel in succession without interrupts.
