1. stm32f4.h add
#include <arm_math.h>
2.system_stm32f4xx.c - void SystemInit(void) add
#if (__FPU_PRESENT == 1) && (__FPU_USED == 1)
SCB->CPACR |= ((3UL <<10*2)|(3UL <<11*2));/* set CP10 and CP11 Full Access */
3.main.c add
#define __FPU_PRESENT
#define __FPU_USED

wxECGAnalyzer - cross platform ECG signal process tool

Detection of abnormal rhythm morphologies is more difficult than normal beat, therefore, we need to collect abnormal rhythm signals in clinical practice  to improve the detection of QRS-complex.

This project is for Electrocardiogram(ECG) signal algorithms design and validation, include preprocessing, QRS-Complex detection, embedded system validation, ECG segmentation, label your machine learning dataset, and clinical trial...etc.

For algorithm performance, in ANSI/AAMI EC38,it is required that the detected QRS shall in the 150ms range of the signed point from annotation by human exper.
