Field Documentation

channel_cfg

struct adc_channel_cfg adc_dt_spec::channel_cfg

Configuration of the associated ADC channel specified in devicetree.

This field is valid only when channel_cfg_dt_node_exists is set to true.

channel_cfg_dt_node_exists

bool adc_dt_spec::channel_cfg_dt_node_exists

Flag indicating whether configuration of the associated ADC channel is provided as a child node of the corresponding ADC controller in devicetree.

channel_id

uint8_t adc_dt_spec::channel_id

ADC channel identifier used by this io-channel.

dev

const struct device* adc_dt_spec::dev

Pointer to the device structure for the ADC driver instance used by this io-channel.

oversampling

uint8_t adc_dt_spec::oversampling

Oversampling setting to be used for that channel.

This field is valid only when channel_cfg_dt_node_exists is set to true.

resolution

uint8_t adc_dt_spec::resolution

ADC resolution to be used for that channel.

This field is valid only when channel_cfg_dt_node_exists is set to true.

vref_mv

uint16_t adc_dt_spec::vref_mv

Voltage of the reference selected for the channel or 0 if this value is not provided in devicetree.

This field is valid only when channel_cfg_dt_node_exists is set to true.
