There are 4 | just a few small guidelines you need to follow. 5 | 6 | ## Contributor License Agreement 7 | 8 | Contributions to this project must be accompanied by a Contributor License 9 | Agreement. You (or your employer) retain the copyright to your contribution; 10 | this simply gives us permission to use and redistribute your contributions as 11 | part of the project. Head over to to see 12 | your current agreements on file or to sign a new one. 13 | 14 | You generally only need to submit a CLA once, so if you've already submitted one 15 | (even if it was for a different project), you probably don't need to do it 16 | again. 17 | 18 | ## Code reviews 19 | 20 | All submissions, including submissions by project members, require review. We 21 | use GitHub pull requests for this purpose. Consult 22 | [GitHub Help](https://help.github.com/articles/about-pull-requests/) for more 23 | information on using pull requests. 24 | -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | 2 | Apache License 3 | Version 2.0, January 2004 4 | http://www.apache.org/licenses/ 5 | 6 | TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 7 | 8 | 1.

Use an mdns module such as netdisco to locate devices on your network. 9 | 10 | Connect to a speaker at 192.168.1.15 11 | 12 | ``` 13 | import temescal 14 | 15 | speaker = temescal.temescal("192.168.1.15") 16 | ``` 17 | 18 | Connect with a registered callback: 19 | 20 | ``` 21 | import temescal 22 | 23 | speaker = temescal.temescal("192.168.1.15", callback=speaker_callback) 24 | ``` 25 | 26 | The callback will be called whenever Temescal receives a packet from the speaker. This may be a response to a sent command or a gratuitous status update triggered by another control event. 27 | 28 | Get the current equaliser state: 29 | ``` 30 | import temescal 31 | 32 | speaker = temescal.temescal("192.168.1.15", callback=speaker_callback) 33 | speaker.get_eq() 34 | ``` 35 | 36 | The callback routine will be called with the response. 37 | 38 | Set the volume to 20: 39 | ``` 40 | import temescal 41 | 42 | speaker = temescal.temescal("192.168.1.15", callback=speaker_callback) 43 | speaker.set_volume(20) 44 | ``` 45 | 46 | This is not an officially supported Google project.
