Description
|
|
-----------
|
|
|
|
The Maxim/Dallas Semiconductor DS2482 is a I2C device that provides
|
|
one (DS2482-100) or eight (DS2482-800) 1-wire busses.
|
|
|
|
|
|
General Remarks
|
|
---------------
|
|
|
|
Valid addresses are 0x18, 0x19, 0x1a, and 0x1b.
|
|
|
|
However, the device cannot be detected without writing to the i2c bus, so no
|
|
detection is done. You should instantiate the device explicitly.
