这两天在驱动HJR买的一个2.0的320*240的屏,需要更改一下字体,但是按照新的码表写进去显示的一直不对
8*8英文字体ascii码示例:
0x00,0x00,0x00,0x00,0x00,0x18,0x18,0x7E, // -+-
0x18,0x18,0x00,0x00,0x00,0x00,0x00,0x00,
之前的8*8字体显示一个字符函数:
void SPILCD_ShowChar(unsigned short x,unsigned short y,unsigned char num, unsigned int fColor, unsigned int bColor,unsigned char flag)
{
unsigned char temp;
unsigned int pos,i,j;
num=num-' ';//µÃµ½Æ«ÒƺóµÄÖµ
i=num*16;
for(pos=0;pos<16;pos++)
{
temp=nAsciiDot[i+pos]; //µ÷ͨµ÷ÓÃASCII×ÖÌå
for(j=0;j<8;j++)
{
if(temp&0x80)
DrawPixel(x+j,y,fColor);
else
if(flag) DrawPixel(x+j,y,bColor); //Èç¹û±³¾°É«±êÖ¾flagΪ1
temp<<=1;
}
y++;
}
}
24*40英文字体ascii码示例:
0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, // -+-
0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,
