【开源获奖案例】智能猫粮控制系统

本期为大家推送迪文开发者论坛的获奖开源案例：智能猫粮控制系统。工程师使用迪文智能屏实现了监测猫粮的温度、湿度、余量，保存猫咪吃粮记录等功能，并别出心裁的设计了一套水墨画风格UI，以及手指触摸时的水墨点击效果，增强触摸的视觉反馈。

方案简介

UI图片素材

迪文智能屏是基于图片完成UI开发，需根据屏幕显示内容提前准备好图片、音频等素材。

界面开发

DGUS软件是通过图层叠加来还原UI效果，将准备好的素材在DGUS软件中组合成完整的画面，并设置好显示、触摸功能。

实现点击特效和音效

通过51程序来获取触摸位置，实现按压效果跟随手指移动，同时实现按键伴音音效。

（1）检测触摸位置代码并播放音频：

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) //第一次点击进入

{

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

touchAnimationFlag = 1;

touchAnimationCnt = 0;

touchPosX = Va[1];

touchPosY = Va[2];

write_dgus_vp(0x00A0, play, 2);

}

}

（2）触摸特效显示的代码如下：

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);

}

}

}

实现猫粮自动出粮

接下来是通过屏幕设定对应的参数，然后数据通过ESP32传输到猫粮控制器，实现猫粮的自动出粮功能，具体代码如下所示：

//获取按键状态

void get_key_status()

{

int i = 0;

//u16 Va=Read_Dgus(addr);

u16 Va=Read_Dgus(0x1000);

if(Va != 0x0000)

{

//状态页

if(Va == 0x0103) //放置g数量

{

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

setNum = placeGramNum;

backPage = 1; //返回状态页

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); //放置一次粮

}

else if(Va == 0x0101) //设置页面

{

u16 switchpage[2] = {0x5A01, 3};

for(i = 0;i < 6;i++)

{

if(i == 0)

{

Write_Dgus(0x3070 + i * 0x10 + 0, currentTime[i] % 10);

Write_Dgus(0x3070 + i * 0x10 + 2, currentTime[i] / 10 % 10);

Write_Dgus(0x3070 + i * 0x10 + 4, currentTime[i] / 100 % 10);

Write_Dgus(0x3070 + i * 0x10 + 6, currentTime[i] / 1000 % 10);

}

else

{

Write_Dgus(0x3070 + i * 0x10 + 0, currentTime[i] % 10);

Write_Dgus(0x3070 + i * 0x10 + 2, currentTime[i] / 10 % 10);

}

}

write_dgus_vp(0x0084, switchpage, 2); //进入设置页

}

else if(Va == 0x0100) //记录页面

{

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

for(i = 0;i < 6;i++)

{

if(i == 0)

{

Write_Dgus(0x2000 + i * 0x10 + 0, eatFeedList[0][i] % 10);

Write_Dgus(0x2000 + i * 0x10 + 2, eatFeedList[0][i] / 10 % 10);
