Protothreads are extremely lightweight stackless threads designed for severely memory constrained systems such as small embedded systems or sensor network nodes.

本代码是一种实现AES-256。此代码加密4种不同的输入数据的128位与4个不同的密钥256位

应用背景正在学习UCOSII，手头又快PIC18F4550的开发板，就在网上找了些例子，自己修改了下，可以在PIC18F4550上跑，对于初学者来说，还是不错！关键技术这个是很简单的一个例子，就是产生一组方波！

这是一个基于金蝶K/3的磅秤插件源代码。安装本差价需要金蝶K/310.0以上的版本。本插件是客户端程序。在车辆过磅时自动产生金蝶K/3的出库单。-This is a based on Kingdee K/3 plug-in source code of the scales. Install this post needs more than Kingdee K/310.0 version. This plug-in is the client program. When weighed in the vehicle automatically generated Kingdee K/3 of出库单.
