stmdsp
The stmdsp project enables certain STM32 development boards to be used as a digital signal processing (DSP) education tool. The solution is portable, and can be used without any external tools or lab equipment.
The project consists of three parts: the firmware, which allows users to upload custom DSP algorithms to process signals in real-time; the hardware, which provides the necessary circuitry for interfacing with signals and the host computer; and the computer software, a program currently named stmdspgui that facilitates algorithm design and execution while also providing numerous analysis features.
Features
- Real-time signal processing: signal readings from the ADC are streamed through the loaded algorithm and outputted over the DAC.
- Supports signal sampling rates from 8kS/s up to 96kS/s.
- Supports signals between -3.3V and +3.3V, with adequate protection for the development board.
- Custom algorithms are uploaded to the hardware at run-time, enabling a faster design and test process.
- Parameter knobs allow for algorithm adjustments while the algorithm is running.
- An on-board signal generator eliminates the need for external generators.
- Numerous analysis features, including signal visualization and measuring algorithm execution time, eliminate the need for other external tools.

folder also contains add-on board schematics and a work-in-progress PDF guide (which may later be abandoned in favor of the wiki).
