51单片机加1602显示计算器C语言源码 可以实现加减乘除，有负数计算 (51 MCU plus 1602 display calculator C language source code Can have negative calculation add, subtract, multiply and divide.)

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. )

WSN的GAF算法程序针对无线传感器网络节点部署密集的特点，提出了 GAF 算法。在 GAF 算法中，根据节点的地理位置信息和节点的无线电发射半径（radio range），传 感器网络部署区域被划分为虚拟单元格（virtual gird）。根据自己的物理位置信 息，各个节点被划入到自己的单元格中。各个节点的物理位置信息可以由 GPS 或 其它定位系统得到。 (GAF algorithm of WSN deployment intensive features for wireless sensor network node, proposed GAF ​ ​ algorithm. In GAF algorithm, the radius of the radio transmitting node and the node' s location information (radio range), the sensor network deployment area is divided into a virtual cell (virtual gird). According to their physical location information, each node is classified into its own cell. The physical position information of each node can be obtained by the GPS or other positioning systems.)
