ADC0809是广泛使用的模／数转换器，在可不采用外部总线结构的单片机系统中(如 由AT89C51组成的系统)。ASC0809的数据线直接与单片结构的I／0 口相连，并由单片机的I／O 口直接对ADC0809进行控制。-ADC0809 is widely used in analog/digital converters, in not using the external bus architecture in the single-chip microcomputer system (such as the composition of the system by the AT89C51). ASC0809 data lines directly with the monolithic structure of I/0 I connected the MCU I/O port directly to control the ADC0809.

这是关于最有控制和鲁棒控制几乎最好的书，内容自包含，非常经典。 本书阐述了当代鲁棒与最优控制的主要和基本的内容，其中包含了作者对该理论作出的重要贡献。 全书共为二十一章。第一章为绪论；第二章是阅读本书的数学基础；第三章为线性系统理论基础；第四章定义了信号的范数以及稳定系统的输入――输出增益；第五章论述了反馈结构的稳定性和性能特征；第六章引入了Bode敏感积分关系和Poisson积分公式在多变量时的形式；第七章讨论了用平衡截断法对线性多变量系统进行降阶；第八章研究Hankel范数近似及其在范数模型降阶中的应用；第九章采用小增益定理对不同模型假设下的系统推导鲁棒稳定性检验；第十章引入线性分式变换（LFT）；第十一章研究了有多个不确定性源的系统鲁棒稳定性及性能。-This the most control and robust control almost the best, the book contains content from the very classic. The book described the contemporary robustness and optimal control of the main and basic content, which contains the authors of this theory make an important contribution. A total of 21 book chapters. Introduction of the first chapter; Chapter II is the book to read the mathematical basis; Chapter III of linear systems theory; Chapter IV definition of the scope of the signal and stability of a number of the input-- output gain; fifth chapter on the structural stability of feedback and performance characteristics; Chapter VI introduced Bode sensitive
