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.

本单片机开发例程含有电路图及C语言，有一定的参考价值-Containing the single-chip circuitry to develop routines and C language, the value of some reference

直流电机速度测量与调节，通过设置不同的按钮来控制奠基的转速，而且显示在数码管上-DC motor speed measurement and regulation, by setting different buttons to control the ground-breaking speed, but also in the digital tube

好东西共享给大家,液晶显示的1502的,单片机51系列的-something good for everyone to share, the liquid crystal display of the 1502, the 8031 Series 51!

Microchip Technology Inc. 的HCS300 是一款跳码编码 器，它是专为安防遥控无钥门禁（RKE）系统而设计 的。 HCS300使用KEELOQ跳码技术，并具有安全性高、 封装尺寸小和成本低等特性。 HCS300 是单向遥控无钥 门禁系统和访问控制系统最完美的解决方案。-The HCS300 from Microchip Technology Inc. is a code hopping encoder designed for secure Remote Keyless Entry (RKE) systems. The HCS300 utilizes the KEELOQ code hopping technology, incorporating high security, a small package outline and low cost. The HCS300 is a perfect solution for unidirectional remote keyless entry systems and access control systems.via any external connection. The EEPROM data is pro-grammable but read-protected. 2006 Microchip Technology Inc.
