12C5A60S2 EEPROM 的读写操作(12C5A60S2 EEPROM read_write)

说明：  STM32F实现USB cdc通信，工程可以直接用(STM32F implements USB cdc communication, and the project can be used directly.)

说明：  stm32FOC电机控制程序，使用FOC2.0的库，通过配置后可用于无刷直流电机、永磁同步电机矢量控制(STm32FOC motor control program, using FOC2.0 library, can be used for brushless DC motor, permanent magnet synchronous motor vector control after configuration.)

51单片机，秒表，C语言,proteus仿真，适合初学者(51 single-chip, stopwatch, C language, proteus simulation, suitable for beginners)

大多数自行车速度表工作通过使用霍尔效应传感器固定在自行车前叉。磁铁是附加到前轮上的辐条之一,它将与霍尔效应开关一次革命的车轮。速度计监测传感器计数轮革命。如果知道车轮的直径,距离可以很容易地计算如果你知道有多少革命的车轮。此外,如果时间完成革命,平均速度也可以计算出来。 对于这个问题,您将编写一个程序来确定总距离(英里)和平均速度(英里每小时)考虑到车轮直径,革命的数量和总时间的旅行。你可以假定前轮从未离开地面,并没有下滑或打滑。(Most bicycle speedometers work by using a Hall Effect sensor fastened to the front fork of the bicycle. A magnet is attached to one of the spokes on the front wheel so that it will line up with the Hall Effect switch once per revolution of the wheel. The speedometer monitors the sensor to count wheel revolutions. If the diameter of the wheel is known, the distance traveled can be easily be calculated if you know how many revolutions the wheel has made. In addition, if the time it takes to complete the revolutions is known, the average speed can also be calculated. For this problem, you will write a program to determine the total distance traveled (in miles) and the average speed (in Miles Per Hour) given the wheel diameter, the number of revolutions and the total time of the trip. You can assume that the front wheel never leaves the ground, and there is no slipping or skidding.)

说明：  是我们学校学生作品只是用来分享，有电路图，有程序，关于51单片机的(Our school is only used to share student work, there are circuit diagrams, a process, on the 51 SCM)

说明：  MPU6050是我们常用的六轴空间位置处理芯片，次文档使用卡尔曼滤波的方式使数据更加的准确(MPU6050 is our commonly used six-axis spatial position processing chip. Kalman filter is used in sub-documents to make the data more accurate.)

说明：  直接频率合成仿真源程序,希望有人能用到.(Direct frequency synthesizer simulation source code, hope someone can use to.)
