本期為大家推送迪文開(kāi)發(fā)者論壇的獲獎(jiǎng)開(kāi)源案例：智能貓糧控制系統(tǒng)。工程師使用迪文智能屏實(shí)現(xiàn)了監(jiān)測(cè)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(huà)風(fēng)格UI，以及手指觸摸時(shí)的水墨點(diǎn)擊效果，增強(qiáng)觸摸的視覺(jué)反饋。

方案簡(jiǎn)介

UI圖片素材

迪文智能屏是基于圖片完成UI開(kāi)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。

界面開(kāi)發(fā)

DGUS軟件是通過(guò)圖層疊加來(lái)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(huà)面，并設(shè)置好顯示、觸摸功能。

實(shí)現(xiàn)點(diǎn)擊特效和音效

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

（1）檢測(cè)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);

}

}

}
