Hi,

[quote user="Y0g1"]great thanks for reply i was able to use it but i done it in a complex way thanks you make it easier for me. one more thing do we need to define below configuration every time when we try to access differnt adc channel in different functions?[/quote]

You can set that as an input to the function you're calling for instance. Or make specific functions matching your sampling requirements.

Depends on how you want it to look and integrate into the rest of your application.

Kind regards,

Håkon

	const struct adc_sequence sequence = {
		.channels = BIT(ADC_1ST_CHANNEL_ID) | BIT(ADC_2ND_CHANNEL_ID) | BIT(ADC_3RD_CHANNEL_ID) | BIT(ADC_4TH_CHANNEL_ID),
		.buffer = m_sample_buffer,
		.buffer_size = sizeof(m_sample_buffer),
		.resolution = ADC_RESOLUTION,
	};

Hi,

There's a modified adc sample here that shows several AD channels:
