将不同型号LCD触摸屏移植的相关问题

u16 TPReadX(void)

{

u16 x=0;

TP_CS();

SpiDelay(10);

//SPI_WriteByte(0xD0);

SPI_WriteByte(0xd0);

SpiDelay(20);

x=SPI_WriteByte(0x00);

x<<=8;

x+=SPI_WriteByte(0x00);

SpiDelay(20);

TP_DCS();

//x = 3671 - x;

x = x>>3;

return (x);

}

u16 TPReadY(void)

{

u16 y=0;

TP_CS();

SpiDelay(10);

//SPI_WriteByte(0x90);

SPI_WriteByte(0x90);

SpiDelay(20);

y=SPI_WriteByte(0x00);

y<<=8;

y+=SPI_WriteByte(0x00);

SpiDelay(20);

TP_DCS();

//y = 3601 - y;

y = y>>3;

return (y);

}

其中，关键位置在向SPI写数据的不同，如果你的触摸屏刚好反了，调换一下这两个就好了。

SPI_WriteByte(0x90);

SPI_WriteByte(0xd0);

另外，在GUI_TOUCH_X_TOUCH.C中，也要做相应的修改。

int GUI_TOUCH_X_MeasureY(void) {

unsigned char t=0,t1,count=0;

unsigned short int databuffer[10]={5,7,9,3,2,6,4,0,3,1};//数据组

unsigned short temp=0,Y=0;

while(count<10) //循环读数10次 //GPIO_ReadInputDataBit(GPIOB,GPIO_Pin_0)==0&&

{

databuffer[count]= 3671 + 273-TPReadY(); //

count++;

}

if(count==10)//一定要读到10次数据,否则丢弃

{

do//将数据X升序排列

{

t1=0;

for(t=0;t<count-1;t++)

{

if(databuffer[t]>databuffer[t+1])//升序排列

{

temp=databuffer[t+1];

databuffer[t+1]=databuffer[t];

databuffer[t]=temp;

t1=1;

}

}

}while(t1);

Y=(databuffer[3]+databuffer[4]+databuffer[5])/3;

// if(X<=3730&&Y<=3730) //个人的屏根据初始参数修改.

// {

// if(X>=330)X-=330;

// else X=0;

// if(Y>=420)Y-=420;

// else Y=0;

// drawbigpoint(240-X/14,320-Y/10);

// }

}

return(Y);

}
