51单片机占空比调速或调光程序，仿真通过，里面有全部程序包括仿真文件(51 microcontroller duty cycle governor or dimming program, through simulation, which all procedures including simulation files)

温度传感器，基于51的温度传感器！献给予51的爱好者们！(Temperature sensor, temperature sensor based on 51! Offered to give 51 fans!)

STM32 RTX实验 内存管理,移植和学习RTX操作系统非常有用(STM32 RTX)

说明：  ec11旋钮编程器C语言使用说明，希望给有用的人一些帮助(Ec11 knob programmer)

电子科大单片机综合实验，功能包括 温度检测 转速测速 温度设定 温差驱动电机速度 按键使用 I2C通信 ，数码管显示 速度 设定温度 实际温度。是个综合学习51单片机的好例子。 (UESTC integrated single-chip experiments, including temperature detection speed tachometer temperature settings temperature difference driving the motor speed keys using I2C communication, digital display speed set temperature actual temperature. Is a good example of a comprehensive study of 51 single-chip.)

说明：  pcf8591AD转换芯片，51单片机控制28BYJ48步进电机(Pcf8591AD conversion chip, 51 single chip computer control 28BYJ48 stepper motor)

测量频率的低电平保持时间，用来测量汽车喷油嘴喷油的时间，单位ms(The low level holding time of measuring frequency is used to measure the injection time of automobile nozzle, unit Ms.)

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)

工程教育中级练习题1：按一下K1键，LED以10Hz频率闪烁，屏幕上画出红圈，跟着闪，放开后保持该频率闪烁；长按K1键超过3秒，LED以5Hz频率闪烁，屏幕上画出红圈，跟着闪，放开后保持该频率闪烁；按一下K2键，LED熄灭；按一下K2键，LED常亮。(Secondary Exercise Question 1 in Engineering Education: Press the K1 key, the LED flickers at 10Hz frequency, draw a red circle on the screen, follow the flash, and keep the frequency flickering after release; Press the K1 key for more than 3 seconds, the LED flickers at 5Hz frequency, draw a red circle on the screen, follow the flash, and keep the frequency flickering after release; Press the K2 key, the LED goes out; Press the K2 key, the LED always shines.)

该文件实现了用温度传感器件DS18B20对温度的采集，并在数码管上显示出来。(This file implements the using temperature sensor DS18B20 the temperature acquisition, and on the digital tube display.)
