此包包括以HD4478位控制器的LCD说明，另外有一89c51为例，采用直连方式编写的lcd驱动程序，效果为将要显示字符以左滚动方式双行显示，难度不大，但体现部分原理，水平不高，共同进步！-HD4478 to the LCD controller note, another example of a 89c51, with Direct Connect approach to the preparation of the LCD driver and the results will be revealed for the characters to the left of double rolling basis, not more difficult, but embodies some principles, the level is not high, and common progress!

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.
