小安派新建工程，连接WiFi

BL模组的SDK文件的examples里面的例程都是用指令开启某个功能的，在实际使用过程中应该都是模组自动化执行逻辑，人为干预越少越好 ## 首先新建一个属于自己的工程文件夹 我是将BL的SDK放在了自己间的一个文件夹里面，自己的工程文件夹和SDK同级目录，如下 `SMART_HOME`文件夹是我的工程文件夹  根据 `Project_basic`工程结构建立文件夹，当然也可以根据自己的习惯随便建立，只要最后在 `CMakeLists.txt`文件里面包含就可以，`build`文件夹无需自己建立，在后面执行 `make`时会自动生成，将 `Project_basic`文件夹内的 `CMakeLists.txt、flash_prog_cfg.ini、Makefile、proj.conf`四个文件复制到自己的工程：  我这边直接将 `wifi和config`文件一起复制过来了，主要是WiFi的初始化和对FreeRtos的移植，完成后需要将 `flash_prog_cfg.ini`文件里面最后部分修改成自己的工程名称，我的工程名称是 `SMART_HOME` ``` [FW] filedir = ./build/build_out/SMART_HOME_$(CHIPNAME).bin address = 0x10000 ``` 修改 `CMakeLists.txt`文件引用WiFi的头文件 ``` # *************************************************************# # 工程源文件配置 # Engineering Source File Configuration # *************************************************************# # ############################ 保持默认 ####################### # ######################### Keep default #################### cmake_minimum_required(VERSION 3.15) include(proj.conf) find_package(bouffalo_sdk REQUIRED HINTS $ENV{BL_SDK_BASE}) # ############################################################# # 搜集所有的C文件( Collect source files) file(GLOB_RECURSE sources "${CMAKE_CURRENT_SOURCE_DIR}/components/*.c") # 添加头文件的引用路径（Add .h include directories） sdk_add_include_directories(main config config) sdk_add_include_directories(main config components/wifi) # sdk_add_include_directories(main config components/uart) # sdk_add_include_directories(main config components/freertos) # 把C文件添加到工程里（Add .c file to the project） target_sources(app PRIVATE ${sources}) # 设置main.c 的文件（Set the document source for main. c） # 注意：不能和file(GLOB_RECURSE sources "${CMAKE_CURRENT_SOURCE_DIR}/components/*.c") 冲突（Note: Cannot conflict with “file(GLOB_RECURSE sources "${CMAKE_CURRENT_SOURCE_DIR}/components/*.c")”） sdk_set_main_file(main/main.c) # 设置工程名称，这个配置决定了编译出来的文件名。(Set the project name, which determines the compiled file name) get_filename_component(PROJECT_NAME ${CMAKE_CURRENT_SOURCE_DIR} NAME) project(${PROJECT_NAME}) ``` 修改 `main`文件，新建 连接WiFi的线程，直接贴代码吧 ``` #include "FreeRTOS.h" #include "task.h" #include "timers.h" #include "mem.h" #include <lwip/tcpip.h> #include <lwip/sockets.h> #include <lwip/netdb.h> // #include "bl_fw_api.h" // #include "wifi_mgmr_ext.h" // #include "wifi_mgmr.h" // #include "bflb_irq.h" // #include "bflb_uart.h" #include "bl616_glb.h" #include "rfparam_adapter.h" #include "board.h" // #include "shell.h" #include "wifi_event.h" #define DBG_TAG "MAIN" #include "log.h" static TaskHandle_t wifi_test_task; extern uint32_t sta_ConnectStatus; static void wifi_test(void *pvParameters) { uint8_t ret = 0; static char *ssid = "qop"; // TODO: 请在这里填上自己 WiFi 的名字和密码 static char *password = "pzypzy888888"; // TODO: 请在这里填上自己 WiFi 的名字和密码 ret = wifi_connect(ssid, password); LOG_I("ret = %d\r\n", ret); while (1) { LOG_I("[wifi_test] ================= \r\n"); vTaskDelay(10000); } } int main(void) { board_init(); tcpip_init(NULL, NULL); wifi_start_firmware_task(); xTaskCreate(wifi_test, "wifi_test", 1024, NULL, 15, &wifi_test_task); vTaskStartScheduler(); while (1) { } } ``` ## 编译 首次打开终端，进入aithinker_Ai-M6X_SDK ``` . install.sh . export.sh ``` 然后进入我们的工程文件夹执行 `make`  编译成功：  下载进板子后连接板子串口，使用串口助手或者PUTTY看串口日志，最后出现 `CODE_WIFI_ON_GOT_IP`说明WiFi连接成功。 ``` [2023-09-29 09:13:09.246]# RECV ASCII> ____ __ __ _ _ _ | _ \ / _|/ _| | | | | | | | |_) | ___ _ _| |_| |_ __ _| | ___ | | __ _| |__ | _ < / _ \| | | | _| _/ _` | |/ _ \| |/ _` | '_ \ | |_) | (_) | |_| | | | || (_| | | (_) | | (_| | |_) | |____/ \___/ \__,_|_| |_| \__,_|_|\___/|_|\__,_|_.__/ Build:08:24:39,Sep 29 2023 Copyright (c) 2022 Bouffalolab team =========== flash cfg ============== jedec id 0xC84017 mid 0xC8 iomode 0x04 clk delay 0x01 clk invert 0x01 read reg cmd0 0x05 read reg cmd1 0x35 write reg cmd0 0x01 write reg cmd1 0x31 qe write len 0x01 cread support 0x01 cread code 0x20 burst wrap cmd 0x77 ===================================== dynamic memory init success, ocram heap size = 251 Kbyte sig1:ffffffff sig2:0000f32f cgen1:9f7ffffd lwip init done sys_mbox_new done! sys_mutex_new done! tcpip thread init done!
