intelligentizePMU

用msp430f5528驱动九轴传感器MPU9250的C语言源代码，开发环境TI公司的CCS。(The source code which is based on CCS is used to drive MPU9250 which has 9-Axis.)

通用可变增益放大器，放大器的增益可设为四档：0.10―1.00，1.0―10.0，10―100，100―1000，程控DAC8043实现 ( Universal variable gain amplifier, the gain of the amplifier can be set to fourth gear: 0.10-1.00,1.0-10.0,10-100,100-1000, programmable DAC8043 implementation)

一个以太网帧解析程序，实现以下功能：解析已封装好的Ethernet V2.0帧封装文件（见附件），判断有多少个帧，每个帧的所有字段内容，检测CRC校验是否正确(An Ethernet frame analysis program, the following functions: parsing the encapsulated Ethernet V2.0 frame encapsulation (see annex), to determine the number of frames, each frame contents all fields to detect CRC checksum is correct)

msp430 g2553 和四线制的lcd1602连接，非常适合g2系列的io少的芯片使用(the msp430 g2553 and the four-wire lcd1602 connection is ideal for G2 Series fewer chips use io)

说明：  首先它能显示环境的温度并能设置上下限阀值，这是最基本的功能，系统上电的时候显示的是当前环境温度和设定的温度阀值，我们可以通过按键来修改温度上下限阀值。(First of all, it can display the environment temperature and set the upper and lower limit threshold, which is the most basic function. When the system is powered on, it displays the current environment temperature and the set temperature threshold. We can modify the upper and lower limit threshold by pressing the key.)

51单片机LED流星雨灯，原理： 利用PWM来模似流星雨：将亮度等级分为8个 ，通过改变每一组LED的亮度来达到流星雨效果。因为流星雨是前面亮后面越来越暗，就像一条龙一样，拖着尾巴过来。(51 single LED meteor light, principle: the use PWM to die like a meteor shower: The brightness level is divided into eight, each group by changing the brightness of the LED to achieve the effect of the meteor shower. Because meteor shower is getting back in front of bright dark, like one-stop, like dragging tail over.)

说明：  ESP8266模块最全资料及网络调试助手，附带STM32实例程序。(ESP8266 module is the most complete data and network debugging assistant, with STM32 example program.)

说明：  基于STM32 V2.0电机库的无传感器FOC控制(Sensorless FOC control based on STM32 V2.0 motor Library)

说明：  使用51单片机控制LED灯，实现交通灯功能。(The use of 51 single-chip computer to control the LED lights to achieve the function of traffic lights.)

说明：  通过51单片机控制驱动芯片298控制两个步进电机画圆的程序(From 51 single-chip control two stepper motors to draw the program)
