This repository provides implementations of ECG signal generation algorithms based on nonlinear dynamical models. The focus is on embedded deployment, enabling real-time ECG synthesis on microcontrollers.

Two numerical integration methods are implemented:

- Explicit RK4 (Runge–Kutta 4th Order)

- Implicit Tustin (Bilinear Transform).

Implementation hardware:

- MCU:  [WeActStudio STM32H523](https://github.com/WeActStudio/WeActStudio.STM32H523CoreBoard/tree/master)

    - Peripherals: 12-bit true DAC

        - PA4 as reference DAC

        - PA5 as signal DAC

- OLED SSD1306 0.96"

- Mini oscilloscope

---

Current implementations:

- A Dynamical Model for Generating Synthetic Electrocardiogram Signals by McSharry et al. 

- Generation of ECG signals from a reaction-diffusion model spatially discretized by Quiroz-Juárez et al.

---

Implementations start with MATLAB / Octave, here is an example form the reaction-diffusion ECG model:
