AdcReport (UORB message)

ADC raw data.

Communicates raw data from an analog-to-digital converter (ADC) to other modules, such as battery status.

TOPICS: adc_report

Fields

Name	Type	Unit [Frame]	Range/Enum	Description
timestamp	uint64	us		Time since system start
device_id	uint32			unique device ID for the sensor that does not change between power cycles
channel_id	int16[16]			ADC channel IDs, negative for non-existent, TODO: should be kept same as array index
raw_data	int32[16]			ADC channel raw value, accept negative value, valid if channel ID is positive
resolution	uint32			ADC channel resolution
v_ref	float32	V		ADC channel voltage reference, use to calculate LSB voltage(lsb=scale/resolution)
