**stm32h7 branch note:** This is a port of stmdsp to the NUCLEO-[H723ZG](https://www.st.com/en/microcontrollers-microprocessors/stm32h723zg.html). This new target processor provides extreme performance improvements over the L4 target, and may become the primary target in the future.
|
|
A minimal copy of ChibiOS is included, modified to support H723xx processors.

# stmdsp
|
|
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](https://www.chibios.org/dokuwiki/doku.php) 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.

|
|
|
**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`.
