台达plC内部寄存器与modbus地址映射表，对想用单片机通过modbus协议控制台达PLC的开发人员有帮助，通过触摸屏接口通讯。-Delta plc internal registers with the Modbus address mapping table, and would like to use single-chip through the Modbus protocol Console PLC Tatsu developer help, through the touch screen interface communication.

这是新版本的u-boot-2012.04移植到mini2440开发板上，现在网上一般都是u-boot-1.1.6的老版本，但是老版本的跟新版本的差别很大，而且新版本的u-boot支持了更多的驱动等，掌握新版的u-boot在mini2440上是很有必要的，在这只上传的将打补丁的源码，另一份是可以直接从官网上下，下完后只要将补丁打上就可以了。

PCI(外设部件互连)是当今个人计算机的主流总线结构，是微型计算机中处理器/存储器与外围控制部件、扩展卡之间的互连接口。PCI局部总线规范是互连机构的协议，也是电气和机械配置的规范。 本书分为9章，涵盖了PCI局部总线规范2.2版及其最新进展，详细介绍了PCI局部总线的原理和操作，内容包括PCI局部总线的基本概念、信号的定义、总线的操作、电气规范、机械规范、配置空间、66 MHz规范、BIOS和PCI-PCI桥等。书中通过大量的时序波形和实例对PCI局部总线的实际应用进行了深入浅出的阐述。 -PCI (peripheral device part interconnection) is now personal computer s mainstream bus structure, is in the microcomputer the processor/memory and between the periphery control portion, the expansion card interconnection connection. The PCI local bus standard is the interconnection organization agreement, is also the standard which the electricity and the machinery dispose. This book divides into 9 chapters, has covered the PCI local bus standard 2.2 edition and the newest progress, introduced the PCI local bus s principle and the operation in detail, the content including the PCI local bus s basic concept, the signal definition, main line s operation, the electricity standard, the mechanical standard, the disposition space, 66 MHz stand
