nios ii 之5110液晶屏（6*8、8*16 ASCII字符，16*16 汉字，常用图标，图案，超全字库+函数代码）
上一篇文章给出了5110液晶屏的驱动和基本操作函数，这里把自己辛苦完成的显示中英文字符，图标和图案的函数代码和字库提供出来。
其中字库和图案部分来自网上他人提供，还有很大部分是自己做的。网上的字库并不完整，我将其扩增了，非常全。我的字库包括：
1.全部 6*8 ASCII 码字库
2.22个 6*8 常用符号（sign），包括希腊字母，数学符号，物理单位，移动标志等
3.35个 10*8 常用图标（icon），包括电池电量，时钟，钥匙，火车，乐符，物理符号，播放器按键符号等
4.全部 8*16 ASCII码字库
5.16*16 汉字，其实就提供了几个，但是提供字模提取软件，非常方便
6.12幅点阵位图，高度为8的倍数
这里贴出几个图，手机拍的，效果不是很好：
至于显示函数，我提供了多种函数。有显示6*8和8*16 ASCII码的，显示6*8符号，10*8图标，显示16*16汉字，显示高度为8倍数的位图。显示函数提供了需要坐标和不需要坐标的两种，这样可以不需要自己计算要在哪显示（即紧接着显示），对于字符串和汉字句子可以自动换行。代码比较多，不过我都注释了，应该不难理解。废话不多说，下面贴出代码：
