# 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

| ---------- | ----------- | ------------ | ---------- | ------------------------------------------------------------------------------------ |
| 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)    |
