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

|
|
| 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 |
