TFT屏显示一个字符，为什么是乱码

void LCD_Show_Char(unsigned int x,unsigned int y,unsigned char value)
{
unsigned char i,j;
unsigned char *temp=Font;

temp+=(value-32)*12;

LCD_SetWindow(x,y,x+11,y+7);       //设置区域
LCD_WriteReg(0x0020,x);
LCD_WriteReg(0x0021,y);
LCD_WR_REG(0x0022);
for(j=0;j<12;j++)
{
        for(i=0;i<8;i++)
        {
                  if(((*temp)&(1<<(7-i)))!=0)
                   {
                    LCD_WR_DATA(0xF800);
                   }
                 else
                  {
                  LCD_WR_DATA(B_COLOR);
                   }
         }
     temp++;
   }
}
