1 准备1.1 硬件和编译环境1.1.1 开发板硬件选用PIC18F25K22，在淘宝上可以买到开发板， LIXUE 工作室出品的。价格在140 左右。1.1.2 IDE编译环境为MPLAB IDE V8.87C 编译器为MCC18，版本号为3.38（以上编译环境均由开发板中的光盘提供）1.1.3 仿真器PICkit3，同一家店买的1.2 FreeRTOS 相关移植文件准备1.2.1 下载移植文件在Microchip 官网下载通用移植文件http://embeddedcodesource.com/rtos我是选了下面这个，点击download 即可下载，解压后里面存在如下文件，1.2.2 查找有用的文件下载到的FreeRTOS为6.0.4 版本1）找到三个.c 文件如上图所示，解压后，主要的文件在FreeRTOS\Source文件夹中，如下所示：其中list.c ， queue.c ，tasks.c 无需修改，作为主要的FreeRTOS的文件，2）找到与.c 文件对应的.h 文件如下图所示，与之对应的在FreeRTOS\Source\include文件夹中：找到list.h ， queue.h ，tasks.h，也无需修改。3）另外还有用的文件包括FreeRTOS.h , portable.h ，projdef.h4）找到heap_1.c找到FreeRTOS\Source\portable\MemMang文件夹里面5）移植修改文件主要包括port.c portmacro.h，在找到FreeRTOS\Source\portable\MPLAB\PIC18F文件夹里面6）其他文件在FreeRTOS_C18\FreeRTOS PrimerEjemplo文件夹中包含了主体的Demo 工程文件，关注FreeRTOSConfig.h，还有两个.lkr 链接文件。2 示例Demo 说明点开FreeRTOS_C18\FreeRTOS PrimerEjemplo 文件夹中的.mcw 工程文件，发现提示丢失文件，如下所示，其实是定位出现文件，依次对应步骤1.2.2 中的各个文件夹位置查找，重新定位即可，定位好之后，编译即可通过，

Keil环境中建立带FreeRTOS的STM32L项目1、先把source文件夹复制至project目录，然后在keil中添加RTOS文件，如图：其中heap_2.c按需选择，可以是heap_1.c等，若需 croutine型任务则还需添加croutine.c文件。2、添加include目录，位于 source下的include文件夹。3、把FreeRTOSConfig.文件复制到source下的indude文件夹，或者其他用户文件夹下也可，这是FreeRTOS的功能配置文件，要按需修改的。4、为了能连接到portmacro.h文件，还需添加include路径Source lportable\RVDS\ARM_CM35、以下移植步骤细节需参考“FreeRTOS在STM32上的移植V1.0”。首先修改PORTMACRO.H文件。基本不用修改。6、port.c文件也基本不用修改。7、PORTASM.S文件在keil环境是不需要的，相关的函数放在了portc文件中。8、修改startup文件（要选择对应芯片的文件，并且要先取消其只读属性）：SVC_Handler修改为vPortSVCHandler PendSV_Handler 修改为xPortPendSVHandler SysTick_Handler修改为xPortSys TickHandler

经过几天的摸索我终于掌握用STM8库的方法，但我还认为不用库也很好，1.首先要装好ST8的开发环境，一个是ST Visual Develop一个是COSMIC stm8C语言编译器.第三把STM8的库下下来2.建立一个新的环境和一个工程，当然工程和环境可同名3.这一点是关键，把STM8库下的*FWLib/project\STVDCosmic STM8_interrupt_vetor.c考到你的新工程目录下4.打开库中的example目录下的一个例子，把除了STM8_interrupt_vetor.c的所有东东考到你的工程下边5，然后把要涉及的文件包进去，这里注意当编译时提示，没有函数时，大家把函数名考一下，到库CHM文件索引下，然后把C文件包含到include6.这时编译大功告成了

PrefaceDuring the past years, there has been a quickly rising interest in radio access technologies for providingmobile as well as nomadic and fixed services for voice, video, and data. The difference indesign, implementation, and use between telecom and datacom technologies is also becoming moreblurred. One example is cellular technologies from the telecom world being used for broadband dataand wireless LAN from the datacom world being used for voice-over IP.Today, the most widespread radio access technology for mobile communication is digital cellular,with the number of users passing 5 billion by 2010, which is more than half of the world’s population.It has emerged from early deployments of an expensive voice service for a few car-borne users,to today’s widespread use of mobile-communication devices that provide a range of mobile servicesand often include camera, MP3 player, and PDA functions. With this widespread use and increasinginterest in mobile communication, a continuing evolution ahead is foreseen.This book describes LTE, developed in 3GPP (Third Generation Partnership Project) and providingtrue 4G broadband mobile access, starting from the first version in release 8 and through the continuingevolution to release 10, the latest version of LTE. Release 10, also known as LTE-Advanced,is of particular interest as it is the major technology approved by the ITU as fulfilling the IMTAdvancedrequirements. The description in this book is based on LTE release 10 and thus provides acomplete description of the LTE-Advanced radio access from the bottom up.Chapter 1 gives the background to LTE and its evolution, looking also at the different standardsbodies and organizations involved in the process of defining 4G. It also gives a discussion of the reasonsand driving forces behind the evolution.Chapters 2–6 provide a deeper insight into some of the technologies that are part of LTE and itsevolution. Because of its generic nature, these chapters can be used as a background not only for LTEas described in this book, but also for readers who want to understand the technology behind othersystems, such as WCDMA/HSPA, WiMAX, and CDMA2000.Chapters 7–17 constitute the main part of the book. As a start, an introductory technical overviewof LTE is given, where the most important technology components are introduced based onthe generic technologies described in previous chapters. The following chapters provide a detaileddescription of the protocol structure, the downlink and uplink transmission schemes, and the associatedmechanisms for scheduling, retransmission and interference handling. Broadcast operation andrelaying are also described. This is followed by a discussion of the spectrum flexibility and the associated
