SigmaDSP Toolbox Proxy

What is This ?

• This is a Python package, with which you can:
  • Control SigmaDSP (ADAU1401/ADAU1701) from PC or ESP32 by:
    • Reading the XML file of SigmaStudio project and generates proxy objects.
    • Proxy objects represent SigmaStudio Toolbox algorithms in your project, and have functions like set_frequency, set_dB, set_coefficients... correspondingly.

Why This ?

• ADAU1401/ADAU1701 are precious for DSP tasks, but I would like to tune filter coefficients automatically, therefore need to control DSP functions on the fly.
• SigmaStudio supports scripting from Python, see SigmaStudio Scripting from Python. However, I prefer that the same package can be used on Windows / Linux, PC / RPi / ESP32 without modification.

Design and Features

• PC control: Can control DSP hardware's behavior from PC, so resources (like Python, AI) are available for filter tuning.
• Portability: The same package can also be used on ESP32 to control SigmaDSP (see here and here).
• Coverage of SigmaStudio Toolbox: one-to-one class mapping for each SigmaStudio Toolbox algorithm (most of them are not tested yet though).
• Easy to use: only the XML file of SigmaStudio project is required. "Factory" will render every thing you need.
• Serialization:
  • Load program and parameters of SigmaDSP from:
    • files:
      • Binary (bytearray) file
      • SigmStudio text files (e.g. NumBytes_IC_1.dat, TxBuffer_IC_1.dat)
      • SigmaStudio project.xml
    • EEPROM
  • Save program and parameters of SigmaDSP to:
    • files:
      • Binary (bytearray) file
      • Text file (converted from binary file)
    • EEPROM
