基于FRDM-KL25Z及简单运放（LM324）设计出了一套小巧、低成本的心电监测装置。它不但能够结合上位机实时显示心电图而且能够将采集的心电信号储存于SD卡，用于24h心电监护，以备观察不同时间段心血管疾病的症状。(FRDM-KL25Z and simple operational amplifier (LM324) based on the designed ECG monitoring device with a set of small, low cost. It can not only combine with the real-time display of the host computer and can store the collected ECG signals in SD card for 24h ECG monitoring for the observation of the symptoms of cardiovascular diseases at different time periods. )

在PROTEUS中用PIC单片机的I/O口模拟串行通信，用键盘控制，并显示，纺真成功！(PROTEUS using the PIC microcontroller I/O port analog serial communication, keyboard control, and display, spinning true success!)

这是一个用51单片机系统仿真ucosii工作的protues电路 本系统包括扩展64k RAM的单片机系统和杨屹移植到51单片机的ucosii 系统 使用方法： 1.安装Protues7.4版，然后用protues打开protues 8051 simulation 文件夹 中的extern ram.DSN 文件 2.打开extern ram.DSN 后，双击单片机在弹出的窗口中的Program File 选项 中选择yy.hex文件。 (yy.hex其实就是yy文件夹中keil文档编译出来的hex文 件，yy文件夹是杨屹的ucos51 系统，用keil 2 可以打开) 3.在Clock Frequency选项中输入22.184M(杨屹的ucos51 用的是22.184M hz的单片机频率) 4.双击VTERM串口调试显示屏，在Baud Rate 选项中选择19200的波特率 5.保存，点击运行就可以看到经典的hello world 了。 (1. Protues7.4 version installed, and then open the protues folder protues 8051 simulation The extern ram.DSN file 2. Open extern ram.DSN, double-click the pop-up window of SCM in the Program File option, select yy.hex file. (yy.hex actually yy folder keil out of the document compiled hex files, yy folder is Yang Yi s ucos51 system, using keil 2 Can open) 3. In the Clock Frequency option to enter 22.184M (Yang Yi of the ucos51 using a microcontroller 22.184M hz frequency) 4. Double-click VTERM serial debug display, in the Baud Rate select 19200 baud rate options 5. Save, click Run you can see the classic hello world)
