README for TinyECC Version 2.0 Author/Contact: An Liu, liuan79@gmail.com Introduction ------------ TinyECC is a software package providing ECC-based PKC operations that can be flexibly configured and integrated into sensor network applications. It provides a digital signature scheme (ECDSA),  a key exchange protocol (ECDH), and a public key encryption scheme (ECIES). It provides a number of optimization switches, which can turn specific optimizations on or off based on developer"s needs. TinyECC 2.0 supports MICA2/MICAz, TelosB/Tmote Sky, BSNV3, and Imote2 motes. It supports SECG recommended 128-bit, 160-bit and 192-bit elliptic curve domain parameters. How to install -------------- 1) Install TinyOS 2.1.1 or later version. ht

51系列单片机通过温湿度传感器采集温湿度数据，然后通过GSM模块进行GSM通信，将数据发送出去。

基于51单片机的GSM智能家居警报系统，能实现周围环境因素的检测，并将信号送达单片机后单片机进行处理，然后通过GSM短信模块发送给用户，完成报警。

应用背景stm32低功耗待机和唤醒，实现低功耗和外部中断唤醒。关键技术我们最终要实现这样一个功能：通过长按（ 3秒） WK_UP按键开机，并且通过DS0DS0DS0的闪烁指示程序已经开始运行， 再次长按该键则进入待机模式的闪烁指示程序已经开始运行。再按一次进入睡眠模式。

我在使用陈明计先生写的small RTOS和51单片机做过几个小项目，起初都很好，开发变的容易了，程序变的容易修改。后来随着任务个数的增多，RAM很快就不够用了。51系列的芯片内部RAM普遍都是256个,很难找出1024个字节RAM或更多，而价格又合适的。记得上一次我没有办法被迫使用了64K flash内部带768字节的XRAM的51芯片，而我根本用不到那么多flash。-I use Mr. Chen Mingji written small RTOS and 51 MCU done several small projects at first were very good to develop easy to change the program become easier to modify. Subsequently, the increase in the number of tasks, RAM is not fast enough. 51 series of chip RAM are generally 256, it is difficult to find 1024 bytes of RAM or more, while prices will be appropriate. I remember the last time I had no way forced to use a 64K flash with 768 bytes of internal XRAM of 51 chips, and I will never use that much flash.
