大家能帮忙解答一下，下面这段程序实现原理吗！ 谢谢大家
void Display_ASCII8X16(uint x0,uint y0,uchar *s)
{
xdata int i,j,k,x,y,xx;
xdata unsigned char qm;
xdata long int ulOffset;
xdata char ywbuf[32],temp[2];
for(i = 0; i<strlen((char*)s);i++)
{
if(((unsigned char)(*(s+i))) >= 161)
{
temp[0] = *(s+i);
temp[1] = '\0';
return;
}
else
{
qm = *(s+i);
ulOffset = (long int)(qm) * 16;
for (j = 0; j < 16; j ++)
{
ywbuf[j]=Zk_ASCII8X16[ulOffset+j];
}
for(y = 0;y < 16;y++)
{
for(x=0;x<8;x++)
{
k=x % 8;
if(ywbuf[y]&(0x80 >> k))
{
xx=x0+x+i*8;
PutPixel(xx,y+y0,BLACK);
}
}
}
}
}
}
