C# 學習筆記（12）hex文件轉bin文件小工具

hex文件格式

hex文件格式網上有很多
我這里參考HEX文件格式詳解https://blog.csdn.net/weixin_39752827/article/details/81477686

編寫hex2bin類

hex轉bin文件的方法很多，但是在做bootLoader工具時，只能接受bin文件就很煩，就有了將hex轉bin集成到自己工具里的想法。
首先去github找了一下，避免重復造輪子，發現了兩個不錯的c#示例
Hex2Bin https://github.com/x893/Hex2Bin
STM32-IAP-HEX-Merge https://github.com/SmartElec/STM32-IAP-HEX-Merge
但是不太滿意，剛好又在學習c#，就動手自己造了個輪子

軟件使用

根據上面的hex2bin類，編寫了一個簡單的示例，hex2bin小工具

可以將hex文件拖拽到軟件打開

可以將未指定的flash地址填充未0

可以分析hex文件地址信息
