八叉树算法

基于小波变换的ECG信号去噪系统设计,在信号采集时，身体的任一微小运动都会产生“基线漂移”，这是一种低频干扰，同时，由于肌电的存在又产生了高频的肌电噪声，由于空间电磁场的存在又使心电信号中混有50Hz的工频干扰。这些噪声不去除，就会影响下一步的信号处理。 综合运用数字信号处理的理论知识进行生物医学信号增强系统设计，实现ECG信号的去噪，从而加深对小波变换及其应用的理解，建立概念多分辨分析的概念，加深理解信号增强的原理、方法和步骤。本设计的主要内容是设计一个基于小波变换的ECG信号去噪系统，实现ECG信号的去噪。 (ECG signal denoising based on wavelet transform system design, signal acquisition, any small movement of the body will have a " baseline drift" , which is a low-frequency interference, while the high frequency due to the existence of the EMG muscle electrical noise due to the presence of electromagnetic field and the ECG signal mixed with a 50Hz power frequency interference. The noise is not removed, it will affect the next step in the signal processing. Use the theoretical knowledge of digital signal processing for biomedical signal enhancement system design to achieve the de-noising of ECG signal, so as to deepen understanding of the wavelet transform and its applications, to establish the concept of multi-resolution analysis of the concept, deepen the understanding of signal enhancement of the principle, the method and steps. The main elements of this design is the design of an ECG signal denoising based on wavelet transform denoising the ECG signals.)

基于avr单片机，1302芯片实现时钟，单字节读写(avr atmega16 ds1302)

此例程运行于内RAM > 1024 Byte的51内核的单片机即可。 比 如 ： SST89E564RD ,STC89C516RD 等 移植ucosii，本例程一共创建了3个任务，任务一开led1,任务二开LED2，任务3关闭led1和led2，并且运行到相应的任务，串口会打印出来，提示当前系统运行的状态。(This routine runs on a single chip computer with 51 cores of RAM > 1024 Byte. For example, SST89E564RD, STC89C516RD and so on For uCOSII, 3 tasks are created in this routine, the task is LED1, task two opens LED2, task 3 closes LED1 and LED2, and runs to the corresponding task, the serial port will be printed out to prompt the state of the current system running.
