| 22 | information see <file:Documentation/driver-api/connector.rst>. |
| 23 | There are three types of messages between w1 core and userspace: |
| 24 | 1. Events. They are generated each time new master or slave device found |
| 25 | either due to automatic or requested search. |
| 26 | 2. Userspace commands. Includes read/write and search/alarm search commands. |
| 27 | 3. Replies to userspace commands. |
