esp32s2关于同时使用wifi和lvgl出错重启是什么原因？

问答对人有帮助，内容完整，我也想知道答案 0 我尝试在用lvgl做一组wifi扫描连接界面，但加入wifi扫描后，esp32s2就不断重启，使用的版本是release4.4，vscode c开发。具体我也去查过，也有人遇到这个问题，他用的是arduino，说是lvgl调用的系统计时和freertos任务调用wifi时起了冲突，但说的很笼统，不太熟悉freertos，头秃搞不明白，有什么办法能解决吗。代码和出错信息如下： Code: [Select all] [Expand/Collapse] /**界面任务**/ static void gui_task(void arg) { xGuiSemaphore = xSemaphoreCreateMutex(); lv_init(); //lvgl内核初始化* lvgl_driver_init(); //lvgl显示接口初始化 static lv_disp_draw_buf_t draw_buf; lv_color_t buf1 = heap_caps_malloc(LV_HOR_RES_MAX LV_VER_RES_MAX * sizeof(lv_color_t), MALLOC_CAP_DMA); lv_color_t buf2 = heap_caps_malloc(LV_HOR_RES_MAX LV_VER_RES_MAX * sizeof(lv_color_t), MALLOC_CAP_DMA); lv_disp_draw_buf_init(&draw_buf, buf1, buf2, LV_HOR_RES_MAX * LV_VER_RES_MAX); /Initialize the display buffer/ static lv_disp_drv_t disp_drv; /A variable to hold the drivers.
