说明：  物联网系统的stm32开发代码，包含一氧化碳，温湿度(Internet of Things System)

ATMEGA128 可以同时改变pwm的频率和占空比，对理解PWM很有处。(ATMEGA128 can change the pwm frequency and duty cycle, and understanding of the PWM is useful at.)

转子系统临界转速的计算，是一个德国人开发的软件，很强大！(rotor modal analysis)

本人做的无线三维室内定位毕业论文程序，可以有效削弱NLOS，时间同步，多径效应的影响，对研究生学习很有帮助。(I make three-dimensional wireless indoor positioning thesis program can effectively weaken the NLOS, time synchronization, multi-path effects, to master Dr. helpful.)

开锁程序,可以通过DA1990a打开门的锁，并不需要注册钥匙。(Unlock procedure, you can open the door lock DA1990a is no need to register the key.)

凌阳单片机实验设备与配套模组\模组资料SPLC501液晶显示V2.1SPLC501DemoCode(Single-chip Sunplus test equipment and complementary modules module data SPLC501 LCD V2.1 SPLC501DemoCode)

这是单片机的安装源程序，这是第一次上传的单片机资料，希望能对大家有用(This is a single chip installation source, this is the first single chip data upload, hope it' ll be useful)

STM32使用USB进行程序IAP升级的源程序，经过实际验证，非常好用(STM32 IAP upgrade using USB for program source code , very easy to use)

graphic.h，c语言图形的头文件，你们看这，有用的话下载一下，其实我上传的原因你们懂的(graphic.h, c language header graphic, you see this, useful, download what, in fact, I understand your reasons for uploading)

0.我使用的是F103VET6，但软件IIC原理都是一样的，改引脚配置后可方便移植 1.连接引脚前，可以只连接VCC和GND查看模块当前地址：模块上的LED指示灯会渐亮，然后就是快闪(1)和慢闪(0)，将值记录下来，用计算器转换一下就是当前的地址值了(0. I use F103VET6, but the principle of software IIC is the same, pin configuration can be easily transplanted. 1. Before connecting pins, you can only connect VCC and GND to view the current address of the module: the LED light on the module will gradually light up, then flash (1) and slow flash (0), record the value, and convert it with a calculator to the current address value.)
