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.

CPLD器件中常用编程，对于多进程做了很好的处理，能实现0到59计数，还可自己根据需要调整，实现多种计数功能，从而实现时分秒计时器的功能-CPLD devices commonly used in programming, for many the process to do a very good deal, can achieve 0-59 count, but also need to be adjusted in accordance with their own, achieve a variety of counting functions, when every minute timer in order to realize the function of timer

已经建立了 usbasp 程序员所述微控制器的程序，但那是另一个长的故事......它需要较高的 2 kb 的引导加载程序的内存。我有 6 kb 的内存来运行所有我 arduino 的项目。满意了我有测试的红外远程、 ds18b20、 hd74480、 模拟、 数字引脚，成功地内 6 kb 内存的 3310 液晶项目但猛地内存不足，当我想要运行的 sd 卡或其他较高的复杂项目。泰文 328 或 168 不是提供给我的国家的所以我想用泰文 16 或 32。但还有一个问题，他们已经不会编译或支持 (出来，fusebit 设置 pin) 给这种类型的微控制器。因此，似乎我是独自在自己的路上。我已经有砖 7 atmega8 尝试 usbasp 和 usbasploader，这是另一个悲惨的故事。我完全用砖其中 9 和成功恢复其中 2 由 avr 单片机 fusebit
