This is the source code for an STM32-based DSP device. The primary goal of this device is to transform signals in real-time, through a GUI for writing and uploading C++ code to the device.

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 rate of 96kS/s
Measuring of filter code in processor clock cycles

Device features:

Read +/- 5V signal(s) off of at least one pin
Send +/- 5V signal(s) off of at least one pin
Communicate with a computer program to allow for the reading, writing, and transformation of signals.

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

Directory explanation: Source code for the device's firmware is in the source directory.
Source code for the accompanying GUI is in gui.
Notebook files for working with the device in Mathematica are in mathematica.
