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](https://www.chibios.org/dokuwiki/doku.php) real-time operating system. +The `stmdsp` project enables certain STM32 development boards to be used as a digital signal processing (DSP) education tool. -**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. +The project consists of two parts: the firmware, which allows users to upload custom DSP algorithms to process signals in real-time; and the GUI currently named [stmdspgui](https://code.bitgloo.com/clyne/stmdspgui), which facilitates algorithm design, upload, and execution, while also providing numerous analysis features. -See the wiki for more information about components of the device's software and hardware. +The firmware for the device is written in C++, building on top of the [ChibiOS](https://www.chibios.org/dokuwiki/doku.php) real-time operating system. -Source code for the device's firmware is in the `source` directory. -Source code for the accompanying GUI is in `gui`. +## Features + +* Real-time signal processing: the input channel is read from the ADC, and the processed output is sent out over the DAC. +* Signal sampling rates from 8kS/s up to 96kS/s. +* Custom algorithms, uploaded over USB at run-time, can be applied to the input signal. +* The second DAC channel can act as a signal generator, should no other input be available. +* Analysis features, including measuring algorithm execution time and logging input and output samples. + +## Supported development boards + +This project is aided by a custom add-on board, which is designed to stack on top of STMicroelectronic's NUCLEO line of dev boards. + +At the moment, only the NUCLEO-L476RG board is fully supported. + +## Programming instructions and more information + +See the `doc` folder for further project documentation, including a PDF guide.
