Rtthread OS 功能开发之 AP6212 模块WiFi联网

以ART-PI为例介绍WiFi的使用方法新建项目工程打开AP6212硬件设备并取消C基础库CTRLS保存。编译程序下载。等待程序运行到了识别网卡成功后代表WiFi模块正式完成初始化。输入WiFi联网指令名称和密码不需要加”wifi join WiFi名称 WiFi密码既可以连接网络。获取到IP地址基本上就已经联网成功了。也可以ping 百度试一下能正常获取返回就代表正常上网了。二、设置自动联网功能在上面的操作中需要手动连接WiFi输入密码和名称这点在实际操作中很麻烦可以使用以下的操作实现WiFi自动联网。首先开启easyflash 软件包并保存。在port 组下面增加以下两个文件。ef_fal_port.c/* * This file is part of the EasyFlash Library. * * Copyright (c) 2015, Armink, armink.ztlgmail.com * * Permission is hereby granted, free of charge, to any person obtaining * a copy of this software and associated documentation files (the * Software), to deal in the Software without restriction, including * without limitation the rights to use, copy, modify, merge, publish, * distribute, sublicense, and/or sell copies of the Software, and to * permit persons to whom the Software is furnished to do so, subject to * the following conditions: * * The above copyright notice and this permission notice shall be * included in all copies or substantial portions of the Software. * * THE SOFTWARE IS PROVIDED AS IS, WITHOUT WARRANTY OF ANY KIND, * EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. * IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY * CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, * TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE * SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. * * Function: Portable interface for FAL (Flash Abstraction Layer) partition. * Created on: 2018-05-19 */ #include easyflash.h #include stdio.h #include stdlib.h #include stdarg.h #include sfud.h #include rthw.h #include rtthread.h #include fal.h /* EasyFlash partition name on FAL partition table */ #define FAL_EF_PART_NAME easyflash /* default ENV set for user */ static const ef_env default_env_set[] { {boot_times, 0} };
