REVEIL Pi CIRRUS - NOTES

FEB 2015


The REVEIL disk image for the Cirrus Logic audiocard and Pi A+ or B+ is designed as a (nearly) plug and play streambox, which uses Darkice to stream to a server at Locus Sonus.

The password of the device is 'soundcamp'

To use the Pi over WiFi, first insert the SD Card in a computer. In the Boot directory, open wifi_settings.txt in a text editor and enter the name and password of your network, retaining the "". Save and eject and insert in the Pi.

If using ethernet, remove the WiFi adaptor.

By default, a stream is set up called  ''

The stream can be heard in a browser by typing the URL in the address bar: 'http://locus.creacast.com:9001/reveil_test.ogg'.

Or from the Locus Sonus soundmap at http://locusonus.org/soundmap/040/ choose 'i' for info and then 'server'; the stream 'reveil_test.ogg' is available from the list.

The Pi appears in the Finder on a Mac as 'reveil-pi-cirrus'. You can connect as User: ''pi'; Password: 'soundcamp'.

Changes to the Darkice stream settings are made in the text file 'Home Directory/Desktop/stream_settings/stream_configuration.cfg'. See the comments there to set stereo/mono, sampleRate, etc. 

// Note that the variable bit rate at which data is streamed is controlled using the 'quality' setting from 0.1 to 1.0. You can choose a setting that gives the best quality possible without dropouts.

// For your stream to appear on the map, open an account at http://locusonus.org/soundmap/admin/login/. Once validated, match the settings in stream_configuration.cfg to the ones you set at the login page above. For help:  info@soundtent.org


The disk image includes some useful features:

// The Pi's IP address is reported in the text file 'ip_address.txt' at 'Home Directory/Desktop'. This is useful for connecting via SSH: In a Terminal window type 'pi@ip_address_of_the_pi', 'yes' to confirm, and the password: 'soundcamp'.

// Darkice streams automatically and the Pi re-connects if there are network issues.

// Multiple failures to connect will cause Darkice to re-start.

// There is an option to re-start the Pi every 24 hours at midnight (disabled by default).

// Darkice info is reported in Home Directory/Desktop/stream_settings/stream_output.txt



There is a simple GUI controller available in the terminal to select the source to record from and the volume. To access the GUI, open a Terminal window, open an SSH connection to the Pi (see above)  and navigate to: 'Desktop/stream_settings'. From here type the command:
sh audio_configuration.sh     then    Enter
