This example shows how to update at regulate period the WWDG counter using theEarly Wakeup interrupt (EWI). The WWDG timeout is set to 262ms, refresh window set to 41h and the EWI isenabled. When the WWDG counter reaches 40h the EWI is generated and in the WWDGISR the counter is refreshed to prevent a WWDG reset and led connected to PC.07is toggled.The EXTI line9 is connected to PB.09 pin and configured to generate an interrupton falling edge.In the NVIC, EXTI line9 to 5 interrupt vector is enabled with priority equal to 0and the WWDG interrupt vector is enabled with priority equal to 1 (EXTI IT > WWDG IT). The EXTI Line9 will be used to simulate a software failure: once the EXTI line9event occurs (by pressing Key push-button on EVAL board) the correspondent interruptis served, in the ISR the led connected to PC.07 is turned off and the EXTI line9pending bit is not cleared. So the CPU will execute indefinitely EXTI line9 ISR andthe WWDG ISR will never be entered(WWDG counter not updated). As result, when theWWDG counter falls to 3Fh the WWDG reset occurs.If the EXTI line9 event don抰 occurs the WWDG counter is indefinitely refreshed inthe WWDG ISR which prevent from WWDG reset. If the WWDG reset is generated, after resuming from reset a led connected to PC.06is turned on. In this example the system is clocked by the HSE(8MHz).

针对城市道路交叉口的常发性交通拥堵现象，依据RFID检测系统的特点，提出了一种基于物联网前端信息采集技术的交通流检测方法。并且对城市道路交叉口采集到的交通流量相对增量、车辆的时间占有率相对增量以及地点平均车速等信息进行了对比性分析和统计推导，从理论上论证了交通拥挤产生时的交通流特点，然后以此为基础给出了交通拥挤事件出现时的判别准则，构造出相应的拥挤检测指标及判别算法。最后利用Matlab编程再结合实际交通测量数据验证了算法的正确性。

This project attempts to implement a Database using B+Tree. The project has developed a DATABASE SYSTEM with lesser memory consumption. Its API includes simple SQL Statements and the output is displayed on the screen. Certain applications for which several features of existing databases like concurrency control, transaction management, security features are not enabled. B+Trees can be used as an index for factor access to the data. Help facility is provided to know the syntax of SQL Statements.

LemonSMS is a component developed in Java that provides a turnkey solution for application developers to incorporate into their Java applications the functionality of sending and processing of incoming SMS messages. LemonSMS acts as a middleware between a Java application and a GSM Modem or Data enabled phone. Because LemonSMS only provides an interface to the added SMS functionality, your application still handles access to data and business logic tier. With the easy-to-use LemonSMS API, developers can easily utilize SMS functionalities provided by LemonSMS.

都是主从板程序，用于zigbee研发，硬件是飞思卡尔的13192sard板。使用时将此程序覆盖掉飞思卡尔所出的smac子程序里的source code即可，主要功能都是通信，而第三个是自动组网程序，主板上电后会将后来上电的sard板加进网络。 编译环境是codewarrior，此编译器使用许可需要购买，16k以下可以免费申请向官方申请。 目前程序很简单，但是编译环境很苛刻，很多人可能没法拿到codewarrior，不过希望能帮到大家。 用途是zigbee，这边没那选项，只好投到相近的RFID领域，毕竟很多是相通的
