In case you haven’t noticed, multimedia communication over IP and wireless net- works is exploding. Applications such as BitTorrent, used primarily for video downloADs, now take up the lion’s share of all traffic on the Internet. Music file sharing, once on the legal cutting edge of massive copyright infringement on col- lege campuses around the world, has moved into the mainstream with signifi- cant legal downloADs of music and video to devices such as the iPod and nu- merous other portable media players.

Mobile operators must continuously pursue cost‐ effective and efficient solutions to meet the high data demand requirements of their subscribers. Limited spectrum allocations and non‐contiguous spectrum blocks continue to pose challenges for mobile operators supporting large data uploads and downloADs across their networks. With the increase in video and social media content, the challenges have increased exponentially.

前言:我從2011年年初開(kāi)始玩LPC1768,在公司做過(guò)幾個(gè)LPC1768的小項(xiàng)目,都是基于UCOS-112.86操作系統(tǒng)和LPC17Xx V2.0固件庫(kù)(還有的基于ulP1.0以態(tài)網(wǎng)協(xié)議棧),產(chǎn)品運(yùn)行穩(wěn)定,芯片級(jí)操作也十分方便(畢竟是基于固件庫(kù)操作,不用管那些復(fù)雜的寄存器),在官網(wǎng)看到不知何時(shí)出了UCOS-I1-V2.91,于是準(zhǔn)備應(yīng)用本版本編寫(xiě)今后的程序,移植時(shí),有意留心寫(xiě)下這篇移植步驟,希望對(duì)初學(xué)者有幫助。一、移植前的準(zhǔn)備工作下載所需文件:1、在LPCWARE官網(wǎng)下載LPC175x 6x CMSIS-Compliant Standard Peripheral Firmware Driver Library(LPC175X,LPC176x固件驅(qū)動(dòng)庫(kù)),下載地址鏈接:http://www.lpcware.com/content/nxpfile/lpc175x6x-cmsis-compliant-standard-perip heral-firmware-driver-library-keil-iar-gnu進(jìn)入網(wǎng)址選擇lpc175x6xcmsis-driver_library.zip下載pctis su amas aer baryp2i56tes(也可以在NXP官網(wǎng)下載,但本人去年下載的固件庫(kù)編譯時(shí)出現(xiàn)N多警告,看E不爽,自己改又不怕改出問(wèn)題)2、在UCOS-1l官網(wǎng)下載UCOS-Il-V291源碼(上面描述為2.89,但實(shí)際內(nèi)核為2.91),下載地址鏈接http://micrium.com/page/downloADs/source_code進(jìn)入網(wǎng)址選擇UC/os-11下載,如下
