将进度条控件和滑块控件属性中的“关联进度条”来实现控件的绑定；
2.用MCU将滑块与文本控件值绑定：
滑块进行拖动的时候，文本控件根据滑块的数值大小进行变化。具体实现过程查看例程函数:" text1="" text2="" text3="" text4="" text5="" text6="" text7="" text8="" text9="" text10="" text11="" text12="" text13="" text14="" text15="" font="2" encode="0" show_bk="0" fore_color="0;0;0" bk_color="255;255;255" xOffset="4" yOffset="36" width="233" height="136" row_gap="0" col_gap="0"/><item name="Text3" id="2" type="text" multi_lang="1" text_align="0" text_align_v="0" text="5.通过Lua脚本控制实现背光亮度调节。
