STM32L476RGTx 开发板，连接心率传感器，通过NB95上报心率实时情况源码

实现超市中排队购物用时最短，是计算机算法设计与分析中的一道题。自己写的程序，原创！(Achieve queued supermarket shopping with the shortest, is a question in the design and analysis of computer algorithms. Write their own procedures, original!)

自己根据3.5库改进的STM32硬件IIC，使用DMA，解决网上其他例程弊病，内含完整工程，运行通过。(IIC STM32 hardware itself according to the 3.5 library improvements, using DMA, other routines to solve the Internet s ills, including complete engineering, running through.)

说明：  stm32驱动mlx90614红外测温，串口一输出(stm32,mlx90614,print via usart1)

说明：  IP通讯协议,基于DSP2812芯片，在CCS3.0开发平台运行(IP communication protocol)

基于51单片机，用DS12C887时钟芯片的电子钟，时间显示采用VFD荧光显示屏显示，效果很好(Based on 51 single-chip DS12C887 clock chip electronic clock, time display using VFD fluorescent display shows good effect)

【实例简介】

二叉树在非递归算法中，后序遍历难度大，很多书上只给出思想或者几段无法直接调试的代码，甚至有些书上是错的，当时我在研究的过程中，就是按着书上错误的代码绕了好半天，几预抓狂。好在最终摸索出来了(Binary Tree in non-recursive algorithm, after the preorder is difficult, given the many books just thinking or paragraphs not directly debugging code, and even on some of the books is wrong, I was in the process of the study, according to the book is error code around for ages, a few pre-crazy. Fortunately, the final fumble out)
