FreeSWITCH学习笔记（一）

FreeSWITCH学习笔记（⼀）【1】FreeSWITCH学习笔记1、Windows安装包下载地址：2、源码下载地址：3、FreeSWITCH后台模式启动命令：freeswitch -nc（即No Console）后台模式没有控制台4、windows平台默认密码已修改为：liu12345、windows平台客户端分别为：X-Lite 和 EyeBeam6、freeswitch默认使⽤UDP的5060端⼝。

如果先启动客户端，会占⽤这个端⼝，所以，建议先启动freeswitch，再启动客户端。

7、如果运⾏freeswitch出现以下错误，是因为端⼝被占⽤了。

Cannot lock pid file /usr/local/freeswitch/run/freeswitch.pid.8、如果输⼊fs_cli，提⽰如下类似错误：[ERROR] fs_cli.c:1610 main() Error Connecting [Socket Connection Error]说明FreeSWITCH没有启动或 mod_event_socket没有正确加载，请检查TCP的8021端⼝是否处于监听状态或被其他进程占⽤。

9、freeswitch -nonatfreeSWITCH启动时默认会启⽤uPnP(或NAT_PMP)协议试图查找你的路由器是否⽀持并在你的路由器上“打洞”，如果你的路由器不⽀持该协议，这⼀步可能耗时⽐较长，因⽽影响启动速度。

所以，如果你只是在内⽹测试并且⼀天启动很多次的话，建议关掉这个选项。

组合参数（后台模式启动），启动命令：freeswitch -nc -nonat10、修改配置XML⽂件后，必须先使⽤命令使之⽣效：reloadxml11、客户端注册错误：（1）提⽰408：Request Timeout⼀般都是由于防⽕墙引起的。

关闭防⽕墙（本地CentOS系统）：临时关闭：service iptables stop永久关闭：chkconfig iptables off（2）提⽰408：forbidden⼀般都是由于账号密码配置错误，鉴权没有通过⽽被禁⽌注册。

FreeRTOS入门（1）——环境搭建

FreeRTOS⼊门（1）——环境搭建1. 开发环境⾸先介绍⼀下相关的开发环境。

不太差劲的⼀台台式机或者笔记本电脑，使⽤Windows 7及以上操作系统，安装有Keil 5；然后是使⽤的开发板，这个选择较多，我采⽤的是OM13092，也就是经典的LPC54608开发板。

2. 环境配置打开Keil新建1个项⽬，选择好相关的芯⽚以后，重点配置RTE：选中ROS以后直接使⽤下⾯的Resolve，可以帮你把需要的组件都选择上，但是有个问题就是，如果需要配置LPC54608的时钟，那就要把SDK Drivers中的clock选中，然后继续使⽤⼀次Resolve，见下图。

这样框架就搭建起来了。

然后就是添加main函数等⽂件。

测试⽂件：#include "FreeRTOS.h"#include "task.h"#include "LPC54608.h"#include "MISC.h"#include "XDLED.h"#include "Console.h"void vTask1(void* pvParameters);void vTask2(void* pvParameters);int main(){BootClockPLL180M();XDLED_Init();Console_Init();xTaskCreate(vTask1, "Task 1", 16, NULL, 1, NULL);xTaskCreate(vTask2, "Task 2", 16, NULL, 1, NULL);vTaskStartScheduler();while (1){}return0;}void vTask1(void* pvParameters){while(1){XDLED_Toggle(1);vTaskDelay(200/portTICK_RATE_MS);}}void vTask2(void* pvParameters){portTickType xLastWakeTime;xLastWakeTime = xTaskGetTickCount();while(1){XDLED_Toggle(2);Console_WriteString("this is task2",13);vTaskDelayUntil(&xLastWakeTime, (500/portTICK_RATE_MS ));}}void vTask3(void* pvParameters){while(1){XDLED_Toggle(3);vTaskDelay(1000/portTICK_RATE_MS); }}。
