esp32s2关于同时使用wifi和lvgl出错重启是什么原因

[20岁开始秃头]

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：

试试把tick task放到 esp_timer 中,而不是放到 freertos tick hook中,可以参考这个example对lvgl的移植
https://github.com/espressif/esp-idf/bl ... ple_main.c

[20岁开始秃头]

感谢，我之前想到了这个，尝试将tick_task放到esp_timer_handle中，可问题仍然未能解决，代码部分如下：

Code: Untitled.c Select all

static void gui_task(void *arg)

    xGuiSemaphore = xSemaphoreCreateMutex();

    lv_init();          //lvgl内核初始化

 	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. Must be static or global.*/

    lv_disp_drv_init(&disp_drv);           /*Basic initialization*/

    disp_drv.draw_buf = &draw_buf;         /*Set an initialized buffer*/

    disp_drv.flush_cb = disp_driver_flush; /*Set a flush callback to draw to the display*/

    disp_drv.hor_res = 240;                /*Set the horizontal resolution in pixels*/

    disp_drv.ver_res = 240;                /*Set the vertical resolution in pixels*/

    // esp_register_freertos_tick_hook(lv_tick_task);

    };

    ESP_ERROR_CHECK(esp_timer_start_periodic(periodic_timer, LV_TICK_PERIOD_MS * 1000));

    // wifi_ap_sta_test();

    uint32_t count = 0;

    while (1)

    {

        vTaskDelay(pdMS_TO_TICKS(10));

        // delay();

        // count++; 

        // if(count == 500){

        //     testExit();

        //     lvgl1_test();

        // }else if(count == 1000){

        //     count = 0;

        //     testExit();

        //     lvgl_test();

        // }

        if (pdTRUE == xSemaphoreTake(xGuiSemaphore, portMAX_DELAY))

        {

            lv_timer_handler();

            xSemaphoreGive(xGuiSemaphore);

        }

    }

    free(buf1);

    free(buf2);

    vTaskDelete(NULL);

}

你这很有可能是多线程引起的问题,操作UI部分,增加互斥看看,我也在用lvgl 不过我是S3芯片

[20岁开始秃头]

感谢，我尝试一下，不过在之前我添加了关键变量的互斥锁，也没起效果

[a2409931477]

哥，你找到原因了吗

[justQin]

我也遇到这个问题了，我不是用的s2，反正不用wifi都正常。
然后我用的spi驱动st7789，我分析代码，感觉是死锁了，一边一直在判断是否在flushing，而这个始终无法被置位，看样子驱动部分得自己写才行了
