The AD7992 is a 12-bit, low power, successive approximation ADC with an I2C-compatible interface. The part operates from a single 2.7 V to 5.5 V power supply and features a 2 μs conver-sion time. The part contains a 2-channel multiplexer and track-and-hold amplifier

说明：  使用STM32F103 32位芯片配置定时器以及控制定时器输出PWM波形(Using STM32F103 32 bit chip to configure timer and control the output PWM waveform of timer)

UMAT user subroutine for ABAQUS in order to define none linear Elastic-plastic material based on the Mises plasticity and none linear isotropic hardening. This UMAT is a good example in order to learn advanced way in defining user material in abaqus finite element program.

成都无线龙实验箱开发板实验，用ARM控制GPRS打电话实验 (Chengdu wireless dragon experimental box development board test, experiment with ARM control GPRS phone)

说明：  利用LTC6802结合stm32检测24芯锂电池电压以及电池温度，还可以实现放电平衡(Test 24 core voltage and temperature)

电子时钟程序，通过VC++编程，实现电子时钟程序，方便编程爱好者交流学习。(Electronic clock procedures, through VC++ programming, electronic clock procedures to facilitate the exchange of learning programming enthusiasts.)

这是我学校电子工程设计的一个题目，是一个基于温度传感器的系统开发，包括了驱动电路，变送器，电源，AD，DA(This is a school of electronic engineering topics, is a temperature sensor-based system development, including a driver circuit, transmitter, power supply, AD, DA)

STM32微处理器硬件IIC实现主机从机通信功能(STM32 microprocessor hardware IIC achieve master slave communication function)

说明：  设计一个基于单片机的嵌入式系统，要求具备以下功能: 红外数据的接收及解码,红外发色电路 数码管的显示驱动控制 将接收到的红外数据进行实时显示(限于动态扫描方法) 请根据以上功能要求，进行硬件系统设计,编写软件程序并画出流程图。 信号波形解码显示都没问题，LED灯和蜂鸣器设计是有点问题的，可以删掉不用不影响。自动使用的是压缩包里第二个文件的程序，其他包里有额外的参考资料，可借鉴。(To design an embedded system based on MCU, the following functions are required: Infrared data receiving and decoding, infrared color circuit Display drive control of digital tube Real time display of received infrared data (limited to dynamic scanning method) According to the above functional requirements, design the hardware system, write the software program and draw the flow chart. Signal waveform decoding display is OK, LED lights and buzzer design is a bit of a problem, can be deleted without affecting. Automatic use of the second file in the compressed package of the program, other packages have additional reference materials, can be used for reference.)
