【开源获奖案例】智能猫粮控制系统
描述
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);
