没整明白，API里面好像没有找到

没理解是什么意思

@regbbs
能不能整个例子，倒腾了几天还是不行
物理按键控制不了滑动

    DataStream_table_1 = lv_table_create(NULL);
    lv_obj_set_pos(DataStream_table_1, 0, 0);
    lv_obj_set_size(DataStream_table_1, 480, 220);
    lv_table_set_col_width(DataStream_table_1, 0, 340);
    lv_table_set_col_width(DataStream_table_1, 1, 130);

    lv_table_set_cell_value(DataStream_table_1,0,0,"Name");
    lv_table_set_cell_value(DataStream_table_1,1,0,"ENGING");
    lv_table_set_cell_value(DataStream_table_1,2,0,"Banana");
    lv_table_set_cell_value(DataStream_table_1,3,0,"Citron");
    lv_table_set_cell_value(DataStream_table_1,4,0,"Name1");
    lv_table_set_cell_value(DataStream_table_1,5,0,"Name2");
    lv_table_set_cell_value(DataStream_table_1,6,0,"Name3");
    lv_table_set_cell_value(DataStream_table_1,7,0,"Name4");
    lv_table_set_cell_value(DataStream_table_1,8,0,"Name5");
    lv_table_set_cell_value(DataStream_table_1,9,0,"Name6");

    lv_table_set_cell_value(DataStream_table_1,0,1,"Value");
    lv_table_set_cell_value(DataStream_table_1,1,1,"68.5 km/h");
    lv_table_set_cell_value(DataStream_table_1,3,1,"$3");
    lv_table_set_cell_value(DataStream_table_1,4,1,"Price1");
    lv_table_set_cell_value(DataStream_table_1,5,1,"Price2");
    lv_table_set_cell_value(DataStream_table_1,6,1,"Price3");
    lv_table_set_cell_value(DataStream_table_1,7,1,"Price4");
    lv_table_set_cell_value(DataStream_table_1,8,1,"Price5");
    lv_table_set_cell_value(DataStream_table_1,9,1,"Price6");

    lv_obj_add_event_cb(DataStream_table_1, DataStream_table_1_event_handler, LV_EVENT_KEY, NULL);
    lv_group_add_obj(groupRect_Diag, DataStream_table_1);//绑定组

那这种界面，有没有控件直接使用

@regbbs
修改回调，是这意思吗
void ui_event_Button( lv_event_t * e)
{
    lv_event_code_t event_code = lv_event_get_code(e);
    lv_obj_t * target = lv_event_get_target(e);

    if (button_fun() == 0) return;//防抖
    LOG_I("get_key :%d", lv_event_get_key(e));
    if ( event_code == LV_EVENT_KEY &&  lv_event_get_key(e) == LV_KEY_RIGHT  )
    {
        lv_group_focus_next(groupRect);
    }
}
void test2()
{
    lv_obj_t * button = lv_btn_create(lv_scr_act());
    lv_obj_set_size(button, 80, 80);
    lv_obj_set_pos(button, 100, 0);
    lv_obj_add_event_cb(button, ui_event_Button, LV_EVENT_ALL, NULL);//UP

    lv_obj_t * button1 = lv_btn_create(lv_scr_act());
    lv_obj_set_size(button1, 80, 80);
    lv_obj_set_pos(button1, 0, 100);
    lv_obj_add_event_cb(button1, ui_event_Button, LV_EVENT_ALL, NULL);//UP

    lv_obj_t * button2 = lv_btn_create(lv_scr_act());
    lv_obj_set_size(button2, 80, 80);
    lv_obj_set_pos(button2, 100, 100);
    lv_obj_add_event_cb(button2, ui_event_Button, LV_EVENT_ALL, NULL);//UP

    //注册组
    groupRect = lv_group_create();
    //绑定组
    lv_group_add_obj(groupRect, button);
    lv_group_add_obj(groupRect, button1);
    lv_group_add_obj(groupRect, button2);

    lv_indev_set_group(indev_keypad, groupRect);//设置默认组

}

回调函数有，但是控件只有部分按键有实际效果

static void keypad_read(lv_indev_drv_t * indev_drv, lv_indev_data_t * data)
{
    static uint32_t last_key = 0;

    /*Get whether the a key is pressed and save the pressed key*/
    uint32_t act_key = keypad_get_key();
    if(act_key != 0) {
        data->state = LV_INDEV_STATE_PR;

        LOG_D("act_key = %d",act_key);
        //beep(1, 100, 50, 0);
        /*Translate the keys to LVGL control characters according to your key definitions*/
        switch(act_key) {
            case 1:
                act_key = LV_KEY_LEFT;//左
                break;
            case 2:
                act_key = LV_KEY_PREV;//上
                break;
            case 3:
                act_key = LV_KEY_RIGHT;//右
                break;
            case 4:
                act_key = LV_KEY_NEXT;//下
                break;
            case 5:
                act_key = LV_KEY_HOME;//返回
                break;
            case 6:
                act_key = LV_KEY_ENTER;//确定
                break;
        }

        last_key = act_key;
    }
    else {
        data->state = LV_INDEV_STATE_REL;
    }

    data->key = last_key;
}

RT-Thread Studio 编译出来的bin，不能直接烧录到ram运行吗，

@tangloong

方便移植吗

E:\Burn>.\Tools\sunxi-fel.exe spl rtthread.bin
SPL: eGON header is not found

E:\Burn>.\Tools\sunxi-fel.exe -p write 0x80000000 rtthread.bin
100% [================================================]   146 kB,  192.7 kB/s

E:\Burn>.\Tools\sunxi-fel.exe exec 0x80000000

好像不太行
