——來自迪文開發(fā)者論壇

本期為大家推送迪文開發(fā)者論壇的獲獎開源案例：智能貓糧控制系統(tǒng)。工程師使用迪文實(shí)現(xiàn)了監(jiān)測貓糧的溫度、濕度、余量，保存貓咪吃糧記錄等功能，并別出心裁的設(shè)計(jì)了一套水墨畫風(fēng)格UI，以及手指觸摸時的水墨點(diǎn)擊效果，增強(qiáng)觸摸的視覺反饋。

    完整開發(fā)資料含迪文屏DGUS工程資料與代碼，可前往迪文開發(fā)者論壇獲?。篽ttp://inforum.dwin.com.cn:20080/forum.php?mod=viewthread&tid=8741&extra=page%3D1

    一、方案簡介：

    1.UI圖片素材

    迪文智能屏是基于圖片完成UI開發(fā)，需根據(jù)屏幕顯示內(nèi)容提前準(zhǔn)備好圖片、音頻等素材。

    2.界面開發(fā)

    DGUS軟件是通過圖層疊加來還原UI效果，將準(zhǔn)備好的素材在DGUS軟件中組合成完整的畫面，并設(shè)置好顯示、觸摸功能。

    3.實(shí)現(xiàn)點(diǎn)擊特效和音效

    通過51程序來獲取觸摸位置，實(shí)現(xiàn)按壓效果跟隨手指移動，同時實(shí)現(xiàn)按鍵伴音音效。

    （1）檢測觸摸位置代碼并播放音頻：

    void TouchDetect()

    {

        u16 Va[3] = 0;

        u8 i = 0;

        for(i = 0;i < 3;i++)

        {

            Va[i] = Read_Dgus(0x0016 + i);

            if(Va[0] == 0x5A01)

            {

            }

           else

            {

                break;

            }

        }

        if(i != 0)  //第一次點(diǎn)擊進(jìn)入

        {

            u16 play[2] = {0x0001, 0x4000};

            touchAnimationFlag = 1;

            touchAnimationCnt = 0;

            touchPosX = Va[1];

            touchPosY = Va[2];

            write_dgus_vp(0x00A0, play, 2);

        }

    }

    （2）觸摸特效顯示的代碼如下：

    void TouchStart()

    {

        if(touchAnimationFlag == 1)

       {

            if(touchAnimationCnt == 0)

            {

                Write_Dgus(0x5011, touchPosX - 100);

                Write_Dgus(0x5012, touchPosY - 100);

            }

            Write_Dgus(0x5000, touchAnimationCnt);

            touchAnimationCnt++;

            if(touchAnimationCnt == 6)

                {

                    touchAnimationFlag = 0;

                    Write_Dgus(0x5011, 1024);

                    Write_Dgus(0x5012, 600);

                }

        }

    }

    4.接下來是通過屏幕設(shè)定對應(yīng)的參數(shù)，然后數(shù)據(jù)通過ESP32傳輸?shù)截埣Z控制器，實(shí)現(xiàn)貓糧的自動出糧功能，具體代碼如下所示：

    //獲取按鍵狀態(tài)

    void get_key_status()

    {

        int i = 0;

        //u16 Va=Read_Dgus(addr);

        u16  Va=Read_Dgus(0x1000);

        if(Va != 0x0000)

        {        

            //狀態(tài)頁   

            if(Va == 0x0103)    //放置g數(shù)量

           {

                u16 switchpage[2] = {0x5A01, 19};

                setNum = placeGramNum;

                backPage = 1;   //返回狀態(tài)頁

                Write_Dgus(0x4000 + 0, setNum % 10);

                Write_Dgus(0x4000 + 2, setNum / 10 % 10);

                Write_Dgus(0x4000 + 4, setNum / 100 % 10);

                Write_Dgus(0x4000 + 6, setNum / 1000 % 10);

                write_dgus_vp(0x0084, switchpage, 2);

            }

            else if(Va == 0x0102)

            {

                OneSendData3(placeGramNum); //放置一次糧

            }
