Software for HiFiBerry boards equipped with DSP. This package can be used to read/write data to HiFiBerry DSP boards using the Beocreate TCP server.
The software comes "as-is". There is no individual support for this software. Feel free to post in the HiFiBerry forum for questions.
Before installing the dsptoolkit, you need to have a working Python 3 installation (>=3.10) and a working pip. You also need to enable SPI as dsptoolkit needs SPI to communicate with the DSP. Check out https://www.raspberrypi-spy.co.uk/2014/08/enabling-the-spi-interface-on-the-raspberry-pi/
You can then install the toolkit by just running
bash <(curl https://raw.githubusercontent.com/hifiberry/hifiberry-dsp/master/install-dsptoolkit)This server runs in background and provides a TCP interface (port 8089) to access DSP functions. It is compatible with SigmaStudio. That means you can directly deploy DSP programs from SigmaStudio and change parameters online.
You can also enable the REST API with this server:
sigmatcpserver --enable-restThe DSP REST API provides a RESTful interface to access metadata, memory, registers, and more from the currently loaded DSP profile. It runs by default on localhost port 13141.
The REST API can be enabled with the sigmatcpserver:
sigmatcpserver --enable-restRead the detailed documentation in doc/restapi.md.
Note: The REST API is the recommended interface for all new development. It provides a more modern, flexible, and powerful way to interact with the DSP.
DEPRECATED: The dsptoolkit command line interface is now considered deprecated. For new development, please use the REST API instead, which provides more functionality and better integration options.
The dsptoolkit command is the legacy command line tool to communicate with the DSP TCP server. The command line parameters are documented in doc/dsptoolkit.md.
We are no longer adding new features to dsptoolkit and it will eventually be phased out. All new development should use the REST API instead.
The software can be used to push filters created by Room Equalisation Wizard (REW) to the DSP. Have a look at the guide in doc/rew-basic.md
DSP profiles can be generated directly in SigmaStudio. However, to enable the full potential of DSP Profiles and allow DSPToolkit to directly control the DSP program, you need to add some additional metadata to the XML file. The process to create a DSP profile is documented in doc/dspprofiles.md
