Pi running connected to the beocreate. SigmaStudio running and this is the message I get:

What to do? Or what do I do wrong?

  Do you have the DSP TCP daemon installed and running?

  I just noticed that a few things where missing in the installation guide of the TCP server. I've updated it now. Please check it again:
  https://www.hifiberry.com/build/documentation/beocreate/beocreate-installing-the-sigmatcpserver/

  Most likely, SPI wasn't enabled.

  I have followed two scenarios. First I expected that the PiBakery script would set all the software and switches in the right position to enable the Sigma Studio access. That doesn't work for me. 

  Then I followed the manual procedure as described in the link from the previous post. So far that does not work either.

  Is there someone who managed to get it up and running?

  Where am I going wrong

  Regards

  Hi Michiel,

  yes, I have it running ;-) Let's try to find out what's wrong in your setup. What's the output of the following commands:

  ls -l /usr/local/bin/beo*
  ps -ef | grep beo

  Yesterday evening I found out the following:

   

  pi@raspberrypi:/tmp $ sudo mv /tmp/config.txt /boot/config.txt
  mv: failed to preserve ownership for ‘/boot/config.txt’: Operation not permitted

  For one reason or another I don't get rights to write in the config.txt file

  In respons to your commands in the previous post I get this:

  pi@raspberrypi:~ $ ls -l /usr/local/bin/beo*
  ls: cannot access /usr/local/bin/beo*: No such file or directory
  pi@raspberrypi:~ $ ps -ef | grep beo
  pi 18638 18433 0 10:23 pts/0 00:00:00 grep --color=auto beo
  pi@raspberrypi:~ $

   

  Thanks in advance

  Regards

  Ok, something didn't work with the installation. Please try again the following commands and post the output here:

  sudo apt-get install -y git cmake
  git clone https://github.com/bang-olufsen/create
  cd create/SigmaTcpDaemon
  cmake .
  make
  sudo cp sigmaTcpDaemon /usr/local/bin/beocreate-tcp
  sudo chown root /usr/local/bin/beocreate-tcp
  sudo chmod u+s /usr/local/bin/beocreate-tcp
  sudo chmod go+rx /usr/local/bin/beocreate-tcp
  cd ../SigmaClientTool
  cmake .
  make
  sudo cp SigmaClientTool /usr/local/bin/beocreate-client
  sudo chown root /usr/local/bin/beocreate-tcp
  sudo chmod go+rx /usr/local/bin/beocreate-tcp

  Best regards,
  Daniel

  Daniel,

  This is the out put. I still get the same message in SigmaStudio.

  This looks good. Now you have installed the TCP Server. It isn't started. You should copy/paste the following to your command line (become root before doing it):

  cat <<EOF >beocreate-tcp.service
  [Unit]
  Description=Beocreate DSP TCP deamon
  After=network.target
  
  [Service]
  Type=simple
  ExecStart=/usr/local/bin/beocreate-tcp
  StandardOutput=null
  Restart=on-failure
  
  [Install]
  WantedBy=multi-user.target
  Alias=beocreate-tcp.service
  EOF
  
  sudo mv beocreate-tcp.service /etc/systemd/system
  sudo systemctl daemon-reload
  sudo systemctl start beocreate-tcp

  Then run the command

  sudo systemctl status beocreate-tcp

  Hi,

  It took some time to spend time on the project.

  It seems to be working now. Sigma Studio seems to be connecting to the raspberry pi and the beocreate board.

  Now time to start learning the Sigma Studio lingo. 

  Perhaps things would speed-up when you give a brief description of the sample set-up. And what your design goals and approach are in there.

  My goals would be:

  1. Low-Pass and High-Pass filter settings simultaneously on both channels; Not per definition the same slope/type for high and low. Output level correction for both drive units, perhaps with some some drive unit anomaly correction.  

  2. Left and Right separate room correction/adaptation equalizers

  I do recognise things in the sample file but do not yet fully grasp how it is implemented

  Thanks in advance

  Regards

  Michiel

  Hi Michiel,

  the important thing is to understand the basic concept - you have inputs and outputs and processing in between. Our sample mixes the inputs from the Raspberry Pi and the SPDIF input, mixes these together, adds a lot of filters (that do nothing be default) and outputs these.

  If you want to create your own crossover using either a crossover block or 2 independent BiQuad filters. I recommend to have a look at these tutorials from AD:

  https://wiki.analog.com/resources/tools-software/sigmastudio/tutorials/filterexamples

  We're planning to do a Google hangout session where we can discuss working with SigmaStudio a bit more in detail. I hope, we can find a time before christmas for this. This will allow us to do this a bit more "hands-on" and demonstrate it live.

  Best regards,
  Daniel
