新新手写学习，不知是哪里的问题，有的字符显示不出来，求解答
//显示一个字符
void OLED_ShowChar(u8 x,u8 y,u8 chr)
{
unsigned int c=0,i=0;
c=(chr-32)*16; //计算偏移值
if(x>120){x=0;y=y+2;}
OLED_Set_Pos(x,y);
for(i=0;i<8;i++)
OLED_WR_Byte(F8X16[c+i],OLED_DATA);
OLED_Set_Pos(x,y+1);
for(i=0;i<8;i++)
OLED_WR_Byte(F8X16[c+i+8],OLED_DATA);
}
//显示字符串
void OLED_ShowString(u8 x,u8 y,u8 chi[])
{
unsigned char j=0;
// unsigned char x=0,y=0;
while (chi!='\0')
{
OLED_ShowChar(x,y,chi[j]);
x+=8;
if(x>120){x=0;y+=2;}
j++;
}
}
void OLED_DISPLAY()
{
OLED_Clear();
OLED_DIS_CHinese(0,0,0);//可以显示
OLED_DIS_CHinese(18,0,1);//可以显示
OLED_DIS_CHinese(36,0,2);//可以显示
OLED_DIS_CHinese(54,0,3);//可以显示
OLED_DIS_CHinese(72,0,4);//可以显示
OLED_DIS_CHinese(90,0,5);//可以显示
OLED_DIS_CHinese(108,0,6);//可以显示
//OLED_ShowString(0,0,"0123456789abcdefg");//显示不了。
OLED_ShowChar(9,2,'C'); //可以显示
OLED_ShowChar(9,4,'7');//可以显示
OLED_ShowChar(9,6,'#');//不可以显示
}
//这个是字串

我试过了，字库前15行是显示不出来的，就是/之前的，0后面是正常的。但前面加再加15行，那15行对应是可以显示的，证明字库应该是没有问题的。就是不知道为什么前15行一个是黑屏。“”号的字符串也是黑屏。
我用赛元 SC92F7545.谢谢
