简述：

这两天在学嵌入式的开发与设计，一切从新开始，从头开始。今天在我的那块实验板上，搞了那个LCD12232点阵的显示。

可是在网上一搜，却没有相关的软件进行简易的计算。每次为了显示一个字，各种算，各种纠结。随想到了自己开发一款小软件。

实验平台：

1.UP－Magic2410

2.模块：LCD12232

LCD12232点阵字库计算器

1.使用说明：

只需要在软件上画出欲显示的图形，下面就将计算出相应的十六进制。挂载进开发板，便可以显示。

2.代码（C#）：

using System;using System.Drawing;using System.Text;using System.Windows.Forms;namespace 点阵生成12232{    public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();
