RS485主机从机通信，程序分模块变成，注释详细(RS485 master slave communication, procedures, sub-modules into a, more notes)

FreeRTOS_KL16FreeRTOS是一个迷你的实时操作系统内核。作为一个轻量级的操作系统，功能包括：任务管理、时间管理、信号量、消息队列、内存管理、记录功能、软件定时器、协程等，可基本满足较小系统的需要(FreeRTOS is a mini real time operating system kernel. As a lightweight operating system, features include: task management, time management, semaphores, message queues, memory management, recording function, software timer, coroutine, can meet the basic needs of the smaller system)

单片机开发系统演示程序 - PS2 键值显示，1位数码管显示键码 (Microcontroller development system demonstration program- PS2 key display, a digital display key code)

自抗扰控制的源码，可以用在无人机控制中，也可以在各种场合替代PID(the source code of ADRC)

此为STC单片机控制的RS485主机通讯控制程序可以实现远距离通讯控制，并可多机控制。(This is the STC Microcontroller RS485 host communications control program can control the remote communication, and multi-machine control.)

通过单片机实现哈希函数SHA-1，C源程序完全可用，已经测试，外部加密芯片采用DS28E01-100(MCU hash function SHA-1, C source code fully available, and has been tested external encryption chip uses DS28E01-100)

单片机控制数字电位器x9313的编程。本编程结合运算放大器设置成一个可调电源，通过单片机控制电位器的阻值修改电位器两端电压从而达到数控电源的效果。电压值可通过单片机外界LCD显示。(Programming of digital potentiometer X9313 controlled by mcu. This program is combined with operational amplifier set into an adjustable power supply, through the MCU control potentiometer resistance, modify potentiometer voltage at the end, so as to achieve the effect of numerical control power supply.Voltage value can be displayed by external LCD of mcu.)
