Bus masters
Bus Masters
The 1-wire adapters are the interface between the computer and the 1-wire bus. In 1-wire lingo, they are called
bus masters.
How to Choose?
- What ports are available?
- Do you want to offload processing from your CPU?
- Do you need advanced bus electrical control (overdrive, active pullup, echo cancelling, logical partitioning)?
