This is the source code for an STM32-based DSP device. The primary goal of this device is to allow custom C++ algorithms to be applied to signals in real-time.

The firmware for the device is written in C++, on top of the ChibiOS real-time operating system.

Features:

  • Read in a signal from the ADC, and either pass-through or apply a filter to the signal before outputting it over the DAC.
  • Sampling rates of up to 96kS/s.
  • Measuring of algorithm performance in processor clock cycles.
  • Flexible signal generator for providing source signals.

See the wiki for more information about components of the device's software and hardware.

Source code for the device's firmware is in the source directory.
Source code for the accompanying GUI is in gui.
