写一个Lvgl搜索wifi并显示可连接的wifi的代码

好的，以下是Lvgl搜索wifi并显示可连接的wifi的代码：

#include "lvgl/lvgl.h"
#include "esp_wifi.h"
#include "esp_event_loop.h"
#include "esp_log.h"
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"

#define WIFI_LIST_NUM 10

static const char *TAG = "wifi_scan";

static lv_obj_t *wifi_list;
static lv_obj_t *wifi_list_label[WIFI_LIST_NUM];

static void wifi_scan_task(void *pvParameter)
{
    uint16_t ap_num = 0;
    wifi_ap_record_t ap_info[WIFI_LIST_NUM];
    memset(ap_info, 0, sizeof(ap_info));

    while (1)
    {
        esp_wifi_scan_start(NULL, true);
        esp_wifi_scan_get_ap_records(&ap_num, ap_info);

        for (int i = 0; i < WIFI_LIST_NUM; i++)
        {
            if (ap_info[i].ssid[0] != 0)
            {
                lv_label_set_text(wifi_list_label[i], (const char *)ap_info[i].ssid);
            }
            else
            {
                lv_label_set_text(wifi_list_label[i], "");
            }
        }

        vTaskDelay(5000 / portTICK_PERIOD_MS);
    }
}

void lv_ex_wifi(void)
{
    wifi_init_config_t cfg = WIFI_INIT_CONFIG_DEFAULT();
    esp_wifi_init(&cfg);
    esp_wifi_set_storage(WIFI_STORAGE_RAM);
    esp_wifi_set_mode(WIFI_MODE_STA);

    wifi_config_t wifi_config = {
        .sta = {
            .ssid = "your_wifi_ssid",
            .password = "your_wifi_password",
        },
    };
    esp_wifi_set_config(WIFI_IF_STA, &wifi_config);
    esp_wifi_start();

    lv_obj_t *scr = lv_obj_create(NULL, NULL);
    lv_scr_load(scr);

    wifi_list = lv_list_create(lv_scr_act(), NULL);
    lv_obj_set_size(wifi_list, LV_HOR_RES, LV_VER_RES);
    lv_list_set_scrollbar_mode(wifi_list, LV_SCROLLBAR_MODE_OFF);
    lv_list_set_style(wifi_list, LV_LIST_STYLE_BG, &lv_style_transp_tight);
    lv_list_set_style(wifi_list, LV_LIST_STYLE_SCRL, &lv_style_transp_tight);
    lv_list_set_style(wifi_list, LV_LIST_STYLE_BTN_REL, &lv_style_transp_tight);
    lv_list_set_style(wifi_list, LV_LIST_STYLE_BTN_PR, &lv_style_transp_tight);
    lv_list_set_style(wifi_list, LV_LIST_STYLE_BTN_TGL_REL, &lv_style_transp_tight);
    lv_list_set_style(wifi_list, LV_LIST_STYLE_BTN_TGL_PR, &lv_style_transp_tight);

    for (int i = 0; i < WIFI_LIST_NUM; i++)
    {
        wifi_list_label[i] = lv_list_add_btn(wifi_list, NULL, "");
        lv_obj_set_style(wifi_list_label[i], &lv_style_transp_tight);
    }

    xTaskCreate(&wifi_scan_task, "wifi_scan_task", 4096, NULL, 5, NULL);
}

希望这个代码能够帮到你！
