C# 学习笔记（12）hex文件转bin文件小工具

hex文件格式

hex文件格式网上有很多
我这里参考HEX文件格式详解https://blog.csdn.net/weixin_39752827/article/details/81477686

编写hex2bin类

hex转bin文件的方法很多，但是在做bootLoader工具时，只能接受bin文件就很烦，就有了将hex转bin集成到自己工具里的想法。
首先去github找了一下，避免重复造轮子，发现了两个不错的c#示例
Hex2Bin https://github.com/x893/Hex2Bin
STM32-IAP-HEX-Merge https://github.com/SmartElec/STM32-IAP-HEX-Merge
但是不太满意，刚好又在学习c#，就动手自己造了个轮子

软件使用

根据上面的hex2bin类，编写了一个简单的示例，hex2bin小工具

可以将hex文件拖拽到软件打开

可以将未指定的flash地址填充未0

可以分析hex文件地址信息
