| Description for a voltage divider, with optional ability to measure |
| resistance of the upper leg. |
| |
| compatible: "voltage-divider" |
| |
| include: base.yaml |
| |
| properties: |
| io-channels: |
| required: true |
| description: | |
| Channels available with this divider configuration. |
| |
| output-ohms: |
| type: int |
| required: true |
| description: | |
| Resistance of the lower leg of the voltage divider |
| |
| full-ohms: |
| type: int |
| description: | |
| Resistance of the full path through the voltage divider. |
| |
| If absent or zero the driver assumes that the upper leg is a |
| resistance-based sensor. |
