中间的乱码,其实显示是32*16 数字5
相关代码如下
void Gui_DrawFont_GBK16(u16 x, u16 y, u16 fc, u16 bc, u8 *s) //数字字符均正常
{
unsigned char i,j;
unsigned short k,x0;
x0=x;
while(*s)
{
if((*s) < 128)
{
k=*s;
if (k==13)
{
x=x0;
y+=16;
}
else
{
if (k>32) k-=32; else k=0;
for(i=0;i<16;i++) //刷Y方向,16次
{
for(j=0;j<8;j++)
{
if(asc16[k*16+i]&(0x80>>j)) //刷X方向,8次
Gui_DrawPoint(x+j,y+i,fc);
else
{
if (fc!=bc) Gui_DrawPoint(x+j,y+i,bc);
}
}
//printf("
%d",asc16[k*16+i]);
}
x+=8;
}
s++;
// printf("

// printf("1111111111111111
");
}
else

{
