此代码示例是一种基本的对资源管理器中 16 发展局对 RS-232 UART 通信。波特率 9600、 8 位数据、 无奇偶校验、 1 停止位、 无流控制

介绍linux 上的c函数库，里面比较详细介绍了函数库文件，对于linux编程来说很好-briefed on the c library containing more detailed document of the library, for instance good linux programming

应用背景该文件将帮助任何人都工作在图形显示的项目水平的数据对齐。字体不包装或压缩，因此使用简单。一个简单的循环会让用户显示字体。使用索引表用户可以找到字体宽度和偏移量的精确位置。使用偏移量用户可以从数据表中查找特定字体的数据。可以使用的字节数可以通过相乘的字体宽度和字体高度来导出。关键技术使用的关键技术是编码和所有的数据被安排整齐地在每个字体文件底部的结构中发现

The widespread use of embedded systems mandates the development of industrial software design methods, i.e. computer-aided design and engineering of embedded applications using formal models (frameworks) and standardized prefabricated components, much in the same way as in other mature areas of engineering such as mechanical engineering and electronics. These guidelines have been used to develop Component-based Design of Software for Embedded Systems (COMDES). The paper gives an overview of the COMDES framework, followed by a presentation of a generic component types, such as function blocks, activities and function units. The execution of function units is discussed in the context of a newly developed execution model, i.e. timed-multitasking, which has been extended to distributed embedded systems.
