It is the source code of the Heap Sort in C++. which is a data structure.

用stm32f103rct6mini板，检测温湿度和气体，DHT11温湿度传感器，MQ-2气体传感器，用TFT LCD显示(Stm32f103rct6mini plate was used to detect temperature and humidity and gas, DHT11 temperature and humidity sensor, mq-2 gas sensor and TFT LCD display)

说明：  基于51单片机的继电器例程，常见问题： 1. 按下按键无效果 确保连线正确 换根杜邦线试试 将单片机拆下来重新安装下，重启开发板(Relay Routine Based on 51 Single Chip Microcomputer, Frequently Asked Questions: 1. Pressing the key has no effect Make sure the connection is correct Try changing the dobang line Remove the microcontroller and reinstall it, restart the development board.)

自己调试的，stm32控制PCF8591输出电压程序，可用运算放大电路调整输出范围，可用于输出检测电压的设备。(Self debugging, STM32 control PCF8591 output voltage procedures, operational amplifier circuit can be used to adjust the output range, can be used to output voltage detection equipment.)

说明：  无线传感器网络的目标跟踪的粒子滤波算法,(WSN tracking using particle filter)

这是个温度检测程序，10K的温度探头，基于STM32F103(This is a temperature detection program, 10K temperature probe)

Decoupling, restore the original signal, Multi-target tracking particle filter, Six degrees of freedom to achieve inverse kinematics algorithm.

字符型液晶显示模块是一种专门用于显示字母、数字、符号等点阵式LCD，目前常用16*1，16*2，20*2和40*2行等的模块。本程序为1602控制程序。(Character LCD module is a kind of lattice LCD which is used to display letters, numbers, symbols and so on. At present, 16*1, 16*2, 20*2 and 40*2 lines are commonly used. This procedure is the 1602 control procedure.)

AD转换，用PCF8591芯片的数模转换程序(a single chip single supply low power eight bit data acquisition device with four analog inputs one analog output)

说明：  中级和高级例程我们会不断更新，此例程主要结合实际开发给用户提供一些实实在在的例程。 程序仅供参考，如有问题可参考基础实验例程内的一些基础程序理解。只要将基础例程学习好，中级和高级都是在此基础上扩展的。本公司不对此部分内容技术支持。(Intermediate and advanced routines will be constantly updated, this routine mainly combined with practical development to provide users with some real routines. The program is for reference only. If you have any questions, you can refer to some basic programs in the basic experimental routine. As long as the basic routines are well studied, both intermediate and advanced levels are extended on this basis. The company does not provide technical support for this part of the content.)
