SIM900开发板配套STM32 GPRS代码(SIM900 STM32 GPRS driver)

51单片机的闪烁灯代码一，非常适合初学者的使用，在这分享给大家。(51 MCU flashing lights code, very suitable for beginners to use, in this share to everyone. )

stm32，通过spi总线实现对于TI的2543AD进行读写操作，串口uart输出数据(stm32, achieved through the spi bus for read and write to TI s 2543AD, serial uart output data)

用于计算同步电机发生三相短路故障时，功角随时间的变化关系。(For the calculation of the three-phase short circuit fault occurs synchronous motors, power angle changes with time.)

由于太阳能充电系统多在户外，为了方便研究太阳能充电控制系统对蓄电池的充电情况，本文使用GPRS无线传输技术，设计了一套太阳能充电系统蓄电池的充电电压电流远程实时监测系统。系统的硬件部分由电压电流检测电路、单片机STC89C52RC、GPRS模块SIM300以及相应的外围电路构成，下位机软件由C语言编写并与硬件部分构成系统下位机部份，实现了对充电电压电流的信息采集以及数据的无线数传。上位机在LabVIEW2010环境下编写，具备友好的人机交互界面，实现了数据的远程接收、实时显示、数据库管理、报表生成和打印等功能。经过系统测试系统实现了对电压电流的远程监测。(As the solar charging system more outdoors, in order to facilitate the study of solar charge control system for charging the battery case, we use GPRS wireless transmission technology, we designed a solar charging system battery charge voltage and current remote monitoring system. The hardware part of the system by the voltage and current detecting circuit, microcontroller STC89C52RC, GPRS module SIM300 and corresponding peripheral circuits, lower computer software written in C language and hardware parts lower position machine part of the system, the realization of the charging voltage and current information collection and wireless data transmission of data. PC at LabVIEW2010 prepared environment, with friendly interactive interface, realize the remote receiving data, real-time display, management, report generation and printing. After the system test system enables remote monitoring of voltage and current.)

基于PSCAD/EMTDC的感应电动机负荷模型对电压恢复的影响。(Influence PSCAD/EMTDC induction motor load model based on voltage recovery.)

基于ARM的俄罗斯方块设计，本次将设计实现一个用C语言编写的、在基于ARM核心的ADuC7020 ARM开发板上实现的单机版的俄罗斯方块小游戏。使用Keil3编程软件对C语言代码进行编写，支持按键操作，在实现过程中涉及了LCD液晶屏的图形显示、按键控制、LED控制、中断、蜂鸣器等嵌入式的编程技术。(Tetris ARM-based design, this will be designed to achieve a C language, the ADuC7020 ARM development board ARM core-based implementations of stand-alone version of the Tetris game. Use Keil3 programming software code written in the C language, support for key operations involved in the implementation process of the LCD screen graphical display, control buttons, LED control, interrupt, buzzer embedded programming techniques.)

说明：  CRC循环的代码，可以用，很详细，欢迎下载(CRC cyclic code can be used, in great detail, are welcome to download)
