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()
{

initFrame();
}

int pY = 0;

/// <summary>

/// </summary>
private void initFrame()
{

最后总结：
呃，本人亦属初学，代码凌乱的地方也请多多见谅。
