在uc/os2 里面的lcd函数,我把其中的Lcd_PutHZ( )移到TQ2440_Test的main了面,头文件也加了,在LCD屏幕上指定坐标点写ASCII码Lcd_PutASCII() 可以显示字母,
可用Lcd_PutHZ( ) 就显示 乱符 .搞不懂unsigned short int QW, 高手有空解答下.
/**************************************************************

void Lcd_PutHZ(unsigned int x,unsigned int y,unsigned short int QW,unsigned int c,unsigned int bk_c,unsigned int st)
{
unsigned short int i,j;
unsigned char *pZK,mask,buf;
pZK = &__CHS[ ( ( (QW >> 8) - 1 )*94 + (QW & 0x00FF)- 1 )*32 ];
for( i = 0 ; i < 16 ; i++ )
{
//左
mask = 0x80;
buf = pZK[i*2];
for( j = 0 ; j < 8 ; j++ )
{
if( buf & mask )
{
PutPixel(x+j,y+i,c);
}
else
{
if( !st )
{
PutPixel(x+j,y+i,bk_c);
}
}
mask = mask >> 1;
}
//右
mask = 0x80;
buf = pZK[i*2 + 1];
for( j = 0 ; j < 8 ; j++ )
{
if( buf & mask )
{
PutPixel(x+j + 8,y+i,c);
}
else
{
if( !st )
{
PutPixel(x+j + 8,y+i,bk_c);
}
}
mask = mask >> 1;
}
}
