按钮使用3.2 tft显示屏和arduino mega

Question

我正在尝试使用arduino mega在3.2 tft lcd上制作一个按钮，我按钮的代码工作。当点击开始测试时，它会将第一个屏幕菜单更改为下一个屏幕。我的代码如下发生这种情况但是当它移动到下一个屏幕时，按钮仍然在后台并且处于活动状态。我试图在按下按钮后删除按钮，这样我就可以在新屏幕上添加新按钮。

代码：

#include <UTFT.h>
#include <ITDB02_Touch.h>



// Declare which fonts we will be using
extern uint8_t SmallFont[];
extern uint8_t BigFont[];
extern uint8_t SevenSeqNumFont[];
             extern unsigned int bird01[0x41A];

   // Uncomment the next two lines for the ITDB02 Shield
   UTFT          myGLCD(SSD1289, 38, 39, 40, 41);
             ITDB02_Touch  myTouch(6, 5, 4, 3, 2);
          // Uncomment the next two lines for the ITDB02 Mega Shield
   //ITDB02        myGLCD(38,39,40,41);   // Remember to add ASPECT_16x9 if            you are using an ITDB02-3.2WC!
  //ITDB02_Touch  myTouch(6,5,4,3,2);
