	Allocate an ADC oneshot unit handle from the pool entry matching init_config->unit_id.
esp_err_t	adc_oneshot_del_unit (adc_oneshot_unit_handle_t handle)
	Release an ADC oneshot unit handle allocated by adc_oneshot_new_unit().
esp_err_t	adc_oneshot_config_channel (adc_oneshot_unit_handle_t handle, adc_channel_t channel, const adc_oneshot_chan_cfg_t *config)
	Cache a channel configuration on the handle. The actual vsf_adc channel_request_once call happens in adc_oneshot_read().
esp_err_t	adc_oneshot_read (adc_oneshot_unit_handle_t handle, adc_channel_t channel, int *out_raw)
	Perform one blocking conversion on a channel and return the raw result.
