RAM的硬件测试程序,经本人测试已经没有问题-RAM hardware test procedures, as I have no problem testing

利用430单片机内部得DA实现的DDS正弦波形产生程序，可以用在对输出波形稳定性很高的场合-430 single-chip internal use of DA may realize the DDS sine wave shape generation process, can be used in high stability of output waveform of occasions

奉上刚做好的测温小制作--基于DS18B20传感器 今个学期刚学了单片机，学期末的时候老师要求每个人都做个有关单片机应用的小制作，而我的作品就是这个。DS18B20挺好用的，功能很强（我用到的只是最简单的）。可惜现在没时间（要考试！），等下吧，考完后我再努力将这个小制作的功能加强，特别是想做到能自动识别传感器ID号的功能。 我知道有很多人都对DS18B20很感兴趣，借此奉上源代码，实物我已经做好了，测温很稳定。希望对大家有帮助。-Thermometry of small production-- DS18B20 sensor based on this semester just learning the microcontroller, the end of the teacher asked each one of the SCM application to be a small production, and I was in the works. DS18B20 very good use, and highly functional (I use only the most simple). Unfortunately, there is no time (to test!) , And so are you, I again after taking the efforts of the small production of functional strengthened, in particular to achieve recognition sensor can automatically ID function. I know that many people are very interested in right DS18B20 to enclose the source code, in-kind I have done well, very stable temperature measurement. We want to help.

在现代电子系统中，有为数众多的IC需要进行相互之间以及与外界的通信。为了提供硬件 的效率和简化电路的设计，PHILIPS开发了一种用于内部IC控制的简单的双向两线串行总线I2C-In modern electronic systems, there are a large number of IC need each other and communicate with the outside world. In order to provide the efficiency and simplify the hardware circuit design, PHILIPS developed an IC for internal control, a simple bi-directional two-wire serial bus I2C.

用8051单片机可实现音乐播放功能（以"新年好"为例）。如果安装了Proteus软件，可方便的在自己的电脑上实现仿真。-YOU KAN PLAY BEAUTIFUL MUSIC WITH THE HELP OF 8051MCU.YOU CAN SIMPLY MAKE IT IF YOU HAVE THE MASTERY OF PROTEUS.

嵌入式系统已经广泛应用于各个科技领域和日常生活的每个角落，由于其本身的特性，使得我们很难发现它的存在。甚至一些从事嵌入式系统开发的科技人员也只知单片机，不知道嵌入式系统。本节从嵌入式系统的定义开始，阐述嵌入式系统的含义、特点等，以使读者加深对嵌入式系统的理解。 -Embedded systems are widely used in various fields of science and technology and everyday life in every corner, due to its own characteristics, making it very difficult for us to discover its existence. Embedded systems and even some involved in the development of scientific and technical personnel are also only single-chip, embedded systems do not know. This section from the beginning of the definition of embedded systems, embedded systems on the meaning, characteristics and so on, in order to enable readers to deepen their understanding of embedded systems.
