说明：  通过单片机控制，实现8个led灯流水显示。(Through the control of the single-chip microcomputer, 8 LED lights are displayed.)

说明：  随着人们对光谱测量仪器灵活性、 微型化的要求 ,便携式光纤光谱仪在实际生产测量中的需求也越来越大 ,对其测量性能的要求也越来越高。根据光纤光谱仪的测量原理 ,利用波长与CCD探测器单元格一一对应的关系 ,提出了一种波长校正的方案 ,波长校准精度可以达到0.5nm ,重复性达0.1nm。(Wit h people′ s requirement for spect rometer are agility and micromation , portable fiber spect rometer is needed more and more widely in practical measurement , and t he requirement for it s measurement capability get s more and more higher . According to t he measurement principle of t he fiber optic spect rometer and the cor responding relationship between t he wavelengt h and the CCD detector′ s cell , a wavelengt h correction met hod is p ut forward in t his paper , t he wavelengt h p recision can reach 0. 5nm and t he repeatability can reach 0. 1 nm.)

基于r7f0c809单片机的便携式电源，可以给手机等消费电子产品充电，具有过电流、过电压、过温保护功能。(The portable power supply based on r7f0c809 MCU can charge mobile phones and other consumer electronic products, and has the functions of over-current, over-voltage and over-temperature protection.)

说明：  适合新手,一共有三个代码,第一个是测试模块,第二个是数据传输模块,第三个是结合MPU6050传输温度湿度的数据,使用的是esp8266(Suitable for beginners, there are three codes, the first is the test module, the second is the data transmission module, the third is the combination of mpu6050 temperature and humidity data transmission, the use of esp8266)

si4432官方代码，EZMacPRO官方协议，对研究SI4432很有帮助(si4432 official code, EZMacPRO official protocol, the study SI4432 helpful)

基于labwindows/cvi设计的温湿度控制上位机软件，可以监测温湿度实时情况。(Based on the labwindows/cvi design of temperature and humidity control of the PC software, can monitor the real-time temperature and humidity.)

51单片机中利用PCF8591进行D/A转换在示波器中显示三角波(51 MCU PCF8591 using the D/A converter in the oscilloscope display triangular wave)

一篇关于步进电机的细分，驱动，加速，减速的文章。(An article on the breakdown of stepper motors, drives, speed up, slow down the article.)

说明：  适用MINI板的基础例程 STM32奋斗板SD卡文件系统例程(Basic routines applicable to MINI boards)

一个数字梯形，选择k条路线，每条路线从第一层的某个数开始，每次进入下一层到达左下或者右下的数字，直到最后一层为止。每条路线不能经过相同的路径，但是可以经过相同的数字节点。 输出一个整数，表示能得到的最大的k条路径经过的数字之和(A digital ladder, the K route, each route the first layer of a number, each time to enter the next layer to reach the left or right next to the number, until the final layer. Each route can not pass through the same path, but can pass through the same number of nodes. Output an integer representing the sum of the number of the largest K paths that can be obtained)
