?本篇文章主要介绍了在DGBUS平台上触摸实现界面切换的方法。
官方开发指南PDF:(不方便下载的私聊我发给你)
在DGBUS平台上使用按键返回控件实现界面切换的功能。
迪文屏型号 | DMG80480T070_09WTC |
DGUS版本 | DGUS_V7646 |
单片机???????? | GD32F407 |
这样设置后,实际运行的时候,当我们点击到这个按键控件,单片机串口会收到:

代码解析:?
?上面框框里的,是我从迪文屏串口接收队列里面取数据。
整个程序流程是这样的,串口DMA接收中断,收到数据后存进 接收队列里面。
然后再程序的另一个地方进行循环的取队列,然后分析处理。
串口接收入队列部分代码:
//ICCARD 20231109 ADDBYLZW
//Com6Obj 改为 ComIcCardObj
ComPortLinkDef ComIcCardObj =ComlinkOp[COM2];

//LCDLCD 20231204 ADDBYLZW

?串口切换界面功能实现:
通过向屏幕发送如下数据实现切换屏幕。
注意:
切换的界面ID要和DGUS里面的界面ID对应起来。

老规矩,养成好习惯,三连走一波,保存、生成、导出。?
????
?
然后就大功告成了~~? ?用SD卡拷贝 DWIN_SET文件夹到SD卡根目录,去烧写屏幕程序验证。
GOOD LUCK~
?
注意?SwitchPage? 函数切换的界面ID要和DGUS里面的界面ID对应起来。
作为一名头秃并且经常眼干的程序猿,要时刻铭记保护好眼睛啊!!? ?文哥我是疼粉的,
还是老规矩,文末来个福利图养养眼,放松一下? ~~
