请问发文版主，您已经提供了详细的显示函数，请问有没有在 main 函数里面的呼叫这些函数的代码可以分享？
这样比较能够了解实际的使用方式，谢谢。

PSIR · 发表于 2013-11-18 14:54:12

楼主您好：

以下这个函数：

//在指定位置显示一个字符
void LCD_ShowChar(u16 x,u16 y,u8 num,u8 size,u8 mode)

里面用到的 asc2_1206 和 asc2_1608 两个自行的二维阵列能不能 PO 上来？
不然没资料可以显示文字。

楼主您好：

在第 2 楼的第 177 行的这个函数：

void LCD_ShowString(u16 x,u16 y,u16 width,u16 height,u8 size,u8 *p); //顯示一個字符串,16字體

可否写一行范例代码？因为里面的 width 和 height 这两个叁数我不知道该怎麽下？

楼主您好：

在第 2 楼的第 177 行的这个函数：

//显示字符串
//x,y:起点坐标
//width,height:区域大小
//size:字体大小
//*p:字符串起始地址
void LCD_ShowString(u16 x,u16 y,u16 width,u16 height,u8 size,u8 *p)
{
      u8 x0=x;
      width+=x;
      height+=y;
while((*p<='~')&&(*p>=' '))//判断是不是非法字符!
{
      if(x>=width){x=x0;y+=size;}
      if(y>=height)break;//退出
      LCD_ShowChar(x,y,*p,size,0);
      x+=size/2;
      p++;
}
}

看红色部分，应该是指在屏幕上的某个区域，写一块大小。
如果不考虑在某个区域，在整个屏幕显示，则可以直接把屏幕的分辨率写进去，比如240*320的屏，即是：width=240，height=320

我的是在OMAPL138上用的。现在能看到通过SPI接口刷屏的动作。可始终没有显示任何东西出来，还做了一个开机logo，也显示不出来。
是不是初始化ILI9341完成后，linux的frambuffer有问题？？？？

一直没搞懂这个到底是什么意思？我用也是ILI9341，也是SPI4线驱动的，但是看了LZ的没有找到读取寄存器函数。希望能给出！

deepway · 发表于 2016-3-29 09:46:14

严重谢了。但像请教下，用并口的话，速度能有多快，实际效果能比出口好多少。最好能搞个动画比较下。如果效果来去不大的话，这样做太浪费资源了！
