Note: This is presently a work in progress, we are adding blocks and structuring the project. Early testers and contributors are welcome. The project is structured around yaml files for liquid blocks, and its easy to add and extend for new blocks: https://github.com/pothosware/PothosLiquidDSP/tree/master/blocks

This toolkit wraps Pothos blocks around the Liquid DSP library. Learn more about capabilities on the LiquidDSP documentation page.

The PothosLiquidDSP contains a set of YAML files which describe processing blocks in terms of their API calls found in the liquid.h header. A python utility called LiquidBlocksGen.py scans the YAML sources and liquid.h header to extract functions and data types which it uses to generate block wrappers. Block descriptions are generated as well so blocks can be used graphically. Each YAML file results in a readable C++ source in the build directory.

The build for PothosLiquidDSP is basically standard CMake project for Pothos toolkits. In addition to installing the LiquidDSP library, the build will also need some additional python modules used for parsing the liquid.h header, and generating the sources which wrap the LiquidDSP API calls.

• Build and install LiquidDSP library: https://github.com/jgaeddert/liquid-dsp/blob/master/README.md
• Python PLY, YAML, MAKO modules are an additional runtime requirement for LiquidBlocksGen.py.

#Ubuntu apt-get install instructions for additional requirements
