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：

头文件中的字库因为实在太多了，这个地方放不下，我放在我CSDN资源里，大家可以免费去下，对了，我把整个工程也打包下，初学者可以参考下,嘿嘿，不过写得不是很专业啦！还请多多指教啊！
