【MCXN947开发板测评】桌面化管理的功能选取与执行 [复制链接]

前面介绍了桌面化管理的界面制作，这次是实现以按键和触摸相组合来实现功能选择与只需，其界面变化如图1和图2所示。

其中，以触摸键来选取功能，以ISP键来进行确认。

 

图1  PWM选项

 

 

图2 控制选项

 

实现功能选择的功能函数为：

void gnxz()
{
     uint8_t i;
    
	  if(f==1)
	  {
		i=n; 
		if(i<7) 
		{
		i++;
		if(i==1)
        {
		BACK_COLOR=RED;
	    POINT_COLOR=WHITE;
		LCD_ShowCharh(80,220,'P',0);
		LCD_ShowCharh(80,212,'W',0);
		LCD_ShowCharh(80,204,'M',0);
		showhanzi16h(80,280,3,1);
		showhanzi16h(80,264,4,1);	
		} 
		if(i==2)
        {
		BACK_COLOR=RED;
	    POINT_COLOR=WHITE;
		LCD_ShowCharh(80,160,'R',0);
		LCD_ShowCharh(80,152,'T',0);
		LCD_ShowCharh(80,144,'C',0);
		BACK_COLOR=WHITE;
	    POINT_COLOR=RED;
		LCD_ShowCharh(80,220,'P',0);
		LCD_ShowCharh(80,212,'W',0);
		LCD_ShowCharh(80,204,'M',0);
		} 
		if(i==3)
        {
		showhanzi16h(80,100,5,0);
		showhanzi16h(80,84,6,0);
		BACK_COLOR=WHITE;
	    POINT_COLOR=RED;
		LCD_ShowCharh(80,160,'R',0);
		LCD_ShowCharh(80,152,'T',0);
		LCD_ShowCharh(80,144,'C',0);	
		}
		if(i==4)
       {
		showhanzi16h(80,100,5,1);
		showhanzi16h(80,84,6,1);
		
        showhanzi16h(180,280,13,0);
		showhanzi16h(180,264,14,0);		
		}
		if(i==5)
        {
		showhanzi16h(180,280,13,1);
		showhanzi16h(180,264,14,1);		
		
		showhanzi16h(180,220,11,0); 
		showhanzi16h(180,204,12,0);	
		
		}
		if(i==6)
        {
		showhanzi16h(180,220,11,1); 
		showhanzi16h(180,204,12,1);	
		
		showhanzi16h(180,160,9,0);
		showhanzi16h(180,144,10,0);	
		}
		if(i==7)
        {
		showhanzi16h(180,160,9,1);
		showhanzi16h(180,144,10,1);	
		
		showhanzi16h(180,100,7,0);
		showhanzi16h(180,84,8,0);			
		}
	}
	else
    {
		showhanzi16h(180,100,7,1);
		showhanzi16h(180,84,8,1);
		showhanzi16h(80,280,3,0);
		showhanzi16h(80,264,4,0);	
		i=0;
	}
	f=0;
	n=i;
	}
}

 

相应的触摸键中断处理函数为：

void TSI0_IRQHandler(void)
{
    if (TSI_GetSelfCapMeasuredChannel(APP_TSI) == BOARD_TSI_ELECTRODE_1)
    {
        if (TSI_GetCounter(APP_TSI) > (uint16_t)(buffer.calibratedData[BOARD_TSI_ELECTRODE_1] + TOUCH_DELTA_VALUE))
        {
		    f=1;
            s_tsiInProgress = false;
        }
    }
    TSI_ClearStatusFlags(APP_TSI, kTSI_EndOfScanFlag);
    SDK_ISR_EXIT_BARRIER;
}

 

进行功能测试的主程序为：

int main(void)
{
	uint8_t i,n;
    gpio_pin_config_t led_config = {
        kGPIO_DigitalOutput,
        0,
    };
		
		gpio_pin_config_t key_config = {
        kGPIO_DigitalInput,
        0,
    };
    CLOCK_SetClkDiv(kCLOCK_DivFlexcom4Clk, 1u);
    CLOCK_AttachClk(BOARD_DEBUG_UART_CLK_ATTACH);
    CLOCK_EnableClock(kCLOCK_Gpio0);
    CLOCK_EnableClock(kCLOCK_Gpio1);
    CLOCK_EnableClock(kCLOCK_Gpio4);
    BOARD_InitPins();
    BOARD_InitBootClocks();
    BOARD_InitDebugConsole();
	GPIO_PinInit(GPIO0, 25U, &led_config);
	GPIO_PinInit(GPIO0, 26U, &led_config);
	GPIO_PinInit(GPIO0, 24U, &led_config);
    GPIO_PinInit(GPIO0, 27U, &led_config);
	GPIO_PinInit(GPIO0, 10U, &led_config);
	GPIO_PinInit(GPIO0, 28U, &led_config);
	GPIO_PinInit(GPIO0, 6U, &key_config);
	delay();
	LCD_LED_High();
	tft_Init();
	LCD_Clear(WHITE);
	jm();
	BACK_COLOR=WHITE;
	POINT_COLOR=RED;
	showhanzi16h(80,280,3,0);
	showhanzi16h(80,264,4,0);	
    // 触摸初始化处理
	f=0;
    n=0;
    while (1)
    { 
		gnxz();
		delay();
		if((GPIO_PinRead(GPIO0, 6U))==0)
		{
             LCD_Clear(WHITE);
			 if(n==7)
			 {
			 show_tbh(80,180,4);
			 BACK_COLOR=WHITE;
	         POINT_COLOR=RED;
			 LCD_ShowStringh(80,140,"Cannot find");
	         LCD_ShowStringh(100,140,"  OV7670 ");
			 LCD_ShowStringh(120,140,"Cannot AI !");
			 delay();
			 }
			 while((GPIO_PinRead(GPIO0, 6U))==1);
			 LCD_Clear(WHITE);
		     jm();	
			 n=0;
             BACK_COLOR=WHITE;
	         POINT_COLOR=RED;
		     showhanzi16h(80,280,3,0);
		     showhanzi16h(80,264,4,0);						
	  }
}

 

经程序的编译与下载，当选取图像功能时会显示图3所示界面。
