说明：  针对MCS-51单片机的硬件结构和原理、指令系统、汇编、中断、定时器、并行扩展等进行了讲解。(The hardware structure and principle, instruction system, assembly, interrupt, timer and parallel expansion of MCS-51 single chip computer are explained.)

ACR9000多轴运动控制器上位机控制程序示例（MFC） (ACR9000 multi-axis motion controller PC control program example (MFC))

说明：  基于STC单片机开发的贪吃蛇游戏，使用一块12864液晶作显示。(a retro snake game program base in STC mcu, 12864 LCD display.)

该程序实现4~20mA直流电流的采集，并通过485通信上传，通信协议为modbus rtu(4~20mA DC current measure)

12864液晶显示，运行环境是AVR单片机。文件问一个工程，可行。(12864 LCD, the AVR microcontroller operating environment. File ask a project feasible.)

NRF82532看门狗程序，能很好的保证单片机系统正常工作，性能十分可靠。(The NRF82532 watchdog program can ensure the normal operation of the single chip microcomputer system and its performance is very reliable.)

人性化的人机交互显示存储系统，通过触摸液晶来实现人机交互，通过sdcard和文件系统fatfs9的配合来实现数据的存储和提取，通过STM32来实现所有的控制工作(User-friendly interactive display storage system, by touching the LCD to achieve human-computer interaction, and file systems via sdcard fatfs9 coordination to achieve storage and retri of data, via STM32 to implement all control work)

时钟功能，调整时间与设定闹钟此两种功能，一键多义功能按键，实现时钟跟闹钟的输出显示(Clock function, adjust the time and set the alarm these two functions, one-touch function keys polysemy to achieve the output of the clock with the clock display)

51单片机控制MAX7219键盘PROTEUS仿真电路控制(51 SCM MAX7219 keyboard PROTEUS simulation circuit control)

这是一个用于工控的上位机系统，可以实时监测温度，露点，湿度。用户可以根据具体情况设定报警点，当达到报警点，系统通过邮件发送报警信息给用户。(This is a PC for industrial control of the system, can be real-time monitoring of temperature, dew point and humidity. Users can set alarms based on specific circumstances, when the police reached, the system, through e-mail warning messages to users.)
