stc15F204EA 0.96寸oled的使用IIC协议，显示图片和只讲屏幕点亮关闭可以，但显示汉字一直不成功，为什么？程序问题吗

};
引脚设置没问题，程序能成功编译

OLED_ShowCN(3,0,1);
  OLED_ShowCN(21,0,2);
看程序参数，第一个应该可以显示字符数组里的第二个字，第二个应该显示全0xff，或全0x00，或乱码，现在是OLED_ShowCN(3,0,1);这个能不能显示出汉字

还是不行，用该程序框架，我让oled亮一会灭一会可以如下：
/****主函数*****/
void main(void)
{
OLED_Init();
delay(5);
//OLED_CLS();
while(1)
{
  OLED_CLS();
  delay(500);
  OLED_Fill(0xff);
  delay(1000);
}
}
当汉字显示还是不行：如下
/****主函数*****/
void main(void)
{
OLED_Init();
delay(5);
//OLED_CLS();
while(1)
{
OLED_ShowCN(3,0,0);
OLED_ShowCN(21,0,1);
delay(500);
}
}
/*******************************************

void OLED_ShowCN(unsigned char x, unsigned char y, unsigned char N)
{
        unsigned char wm=0;

        for(wm = 0;wm < 16;wm++)
        {

                adder += 1;
        }
        OLED_SetPos(x,y + 1);
        for(wm = 0;wm < 16;wm++)
        {
                Write_IIC_Data(F16x16[adder]);
                adder += 1;
        }
