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
Write_IIC_Data(F16x16[adder])中adder的值有没有问题，另外F16x16[]好像是两个字，第二个字是什么，程序好像应该能显示第二个字
恩，第一个炜字是共阳极取的，第二个是共阴极取的，我用来判断我取的是否有问题
程序中adder的值不是adder=32*N;N表示F16x16[]中的第几个汉字吗
按正常思路第二个炜字可以正常显示，但实际一直黑屏，以下这个显示图片的就能正常运行，那么oled屏自身应该没问题吧

我也是刚学习这个的，，取的字模都是按设定，共阴——列行式——逆向输出，描点函数指的是这个吗
/*******************************************

{

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

}
}
用的也都是网上能获取的例程拿来用的，图片能显示，汉字就不能显示很困惑
没看到这个代码OLED_SetPos(x , y);，或者直接用 Write_IIC_Command(0xb0+y);来代替，有可能地址设置出错，显示汉字前先清屏，这样除非显示全空，不然总会有点东西显示。另外unsigned int adder=32*N;，建议改为unsigned int adder=32*（N-1）;，数组起始应该是0。
/*******************************************
//OLED设置起始坐标
********************************************/
void OLED_SetPos(unsigned char x, unsigned char y)
{
Write_IIC_Command(0xb0+y);
Write_IIC_Command(((x&0xf0)>>4)|0x10);
Write_IIC_Command((x&0x0f)|0x01);
}
//unsigned int adder=32*N;改为unsigned int adder=32*（N-1）;不就是将N 从0开始取，变为从1开始取吗
最好把显示地址固定，直接写死，比如屏幕的最左上角为显示起点，现在查问题，能固定的参数最好都固定了。至于N，只是在于你如何定义而已，如果定义N =0为数组中第一个汉字，那就不需要做N-1，如果定义N=1为数组第一个汉字，那就应该要做N-1了
谢谢你的建议，改了另一个例程，能够成功显示了，问了懂的朋友，说是oled中的函数有问题，相信日后会慢慢把问题找出来
