| 15 | Description |
| 16 | ----------- |
| 17 | |
| 18 | The Maxim/Dallas Semiconductor DS2482 is a I2C device that provides |
| 19 | one (DS2482-100) or eight (DS2482-800) 1-wire busses. |
| 20 | |

| 22 | General Remarks |
| 23 | --------------- |
| 24 | |
| 25 | Valid addresses are 0x18, 0x19, 0x1a, and 0x1b. |
| 26 | However, the device cannot be detected without writing to the i2c bus, so no |
| 27 | detection is done. You should instantiate the device explicitly. |
