17 | ||
2216886b | 18 | The Maxim/Dallas Semiconductor DS2482 is a I2C device that provides |
baf12ae2 EP |
19 | one (DS2482-100) or eight (DS2482-800) 1-wire busses. |

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 | |
0314b020 | 27 | detection is done. You should instantiate the device explicitly. |
