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. )

说明：  超声波传感器数据采集，arduino实现。并在道路检测中使用(The data acquisition of ultrasonic sensor is realized by Arduino. And it is used in road detection)

这是一个32位stm32F103c8t6程序，配合摩托车皮带轮的表面检测用的电涡流传感器，步进电机转一周，adc模块。(This is a 32 stm32F103c8t6 program, with the motorcycle pulley surface inspection using eddy current sensors, stepper motor revolution, adc module.)

这个程序是RDS收音机的解码程序，RDS的付载波中包含中英文字的区位编码，通过接收后程序解码出中文或英语字符并显示在LCD上(This program is RDS radio decoder, RDS carrier is included in the payment of the location code word, decoding by the program after receiving a Chinese or English characters and displayed on the LCD)

将hex文件发送给单片机，串口发送，快速方便，用于stm32(Hex file to the SCM serial, send, quickly and easily, for STM32)

51单片机上运行的uCos操作系统，已调试通过，可以直接下载使用，但是要注意内存大小 ，STC12C5A60S2可以使用片内存储器，不需要外扩。(STC12C5A60S2 uCOS system)

zigbee实现LCD的检测，测试LCD能否正常工作,LCD的型号是12684(zigbee achieve the LCD inspection, testing LCD can work, LCD model is 12,684)

该程序实现了用单片机来控制时钟芯片DS1302进行万年历的显示。 这个代码相对来说很复杂，注释比较多。 程序运行，首先设置时间。 按S19，进行某一位的设置，会看到某一位上面会闪烁。 按S20，数值加1. 按S21，数值减1. 设置完后，时间会进行运行。 另外,1602上也会有时间显示的。(The program implements the MCU to control the clock chip DS1302 conducted calendar display. This code is relatively complex, comment more, we can carefully analyzed. The program runs, the first set the time. By S19, conducted a one set, you will see a bit above flashes. By S20, the value plus 1. By S21, the value minus 1. After setting, the time will be run. Further, the time will be displayed in 1602.)

按键判断 进行行扫描m表示对应的行数 n表示对应的列数 对应数值亮(Judgment keystroke scan lines express the corresponding m number of rows n that corresponds to the number of rows corresponding numerical Liang)

这是一个在万能充电器中能自动识别电池极性的电路图，非常巧妙的设计(This is a universal battery charger can automatically identify the polarity of the circuit, very clever design)
