# AdcReport (UORB message)
ADC raw data.
Communicates raw data from an analog-to-digital converter (ADC) to other modules, such as battery status.
[source file](https://github.com/PX4/PX4-Autopilot/blob/main/msg/AdcReport.msg)
**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) |
