# stmdsp
|
|
|
|
The *stmdsp* project enables certain [NUCLEO development boards](https://www.st.com/en/evaluation-tools/stm32-nucleo-boards.html) to be used as an educational tool for digital signal processing (DSP). The solution is portable, and can be used without any external tools or lab equipment.
|
|
|
|
The project consists of three parts:
|
|
1. Firmware that allows users to upload custom DSP algorithms to process signals in real-time.
|
|
2. A [custom add-on board](https://code.bitgloo.com/clyne/stmdsp/wiki/DSP-add-on-board) which provides the necessary circuitry for interfacing with signals and the host computer.
|
|
3. [Computer software](https://code.bitgloo.com/clyne/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 binary and out the DAC.
|
|
* Custom algorithms are uploaded to the hardware at run-time, enabling a fast design and test process.
|
|
* Supports signal sampling rates from 8kS/s up to 96kS/s, with buffer size of up to 4,096 samples.
|
|
* Supports signals between -3.3V and +3.3V, with adequate protection for the development board.
|
|
* Two parameter knobs allow for algorithm adjustments while the algorithm is running.
|
|
* An on-board signal generator eliminates the need for inputs from external hardware.
|
|
* Numerous analysis features, including signal visualization and algorithm execution time measurement, eliminate the need of other equipment such as oscilloscopes.
