The CommScope InstaPATCH® 360 and ReadyPATCH® solutions utilize a standards-compliant multi-fiber connector to provide high density termination capability. The connector is called an MPO (Multi-fiber Push On) connector by the standards. In many cases, multi-fiber connector products are referred to as MTP connectors. This document is intended to clarify the difference between the two terms – MPO and MTP.

前言:我从2011年年初开始玩LPC1768,在公司做过几个LPC1768的小项目,都是基于UCOS-112.86操作系统和LPC17Xx V2.0固件库(还有的基于ulP1.0以态网协议栈),产品运行稳定,芯片级操作也十分方便(毕竟是基于固件库操作,不用管那些复杂的寄存器),在官网看到不知何时出了UCOS-I1-V2.91,于是准备应用本版本编写今后的程序,移植时,有意留心写下这篇移植步骤,希望对初学者有帮助。一、移植前的准备工作下载所需文件:1、在LPCWARE官网下载LPC175x 6x CMSIS-compliant Standard Peripheral Firmware Driver Library(LPC175X,LPC176x固件驱动库),下载地址链接:http://www.lpcware.com/content/nxpfile/lpc175x6x-cmsis-compliant-standard-perip heral-firmware-driver-library-keil-iar-gnu进入网址选择lpc175x6xcmsis-driver_library.zip下载pctis su amas aer baryp2i56tes(也可以在NXP官网下载,但本人去年下载的固件库编译时出现N多警告,看E不爽,自己改又不怕改出问题)2、在UCOS-1l官网下载UCOS-Il-V291源码(上面描述为2.89,但实际内核为2.91),下载地址链接http://micrium.com/page/downloads/source_code进入网址选择UC/os-11下载,如下
