书接上回,将WIFI名称和密码保存到存储当中。
使用easyflash保存WIFI名称和密码
创建 存储相关代码

修改web/mlwip_https.c增加如下内容:
#include "storage.h"
#include "wifi_event.h"
#include "log.h"
....
// 将 wifi 信息写入 存储
flash_erase_set(SSID_KEY, ssidValue);
flash_erase_set(PASS_KEY, pwdValue);
// 开启 sta 模式,连接WIFI
// 重启设备
LOG_W("system 2s reset ");
vTaskDelay(2000/portTICK_PERIOD_MS);
GLB_SW_System_Reset();
修改proj.conf增加如下内容:
# easy flash
set(CONFIG_PARTITION 1)
set(CONFIG_BFLB_MTD 1)
set(CONFIG_EASYFLASH4 1)
修改CMakeLists.txt增加如下内容:
...
sdk_add_include_directories(storage)
...
target_sources(app PRIVATE
storage/storage.c
web/cJSON.c
web/mlwip_https.c
)
