突然要用 STC 写个东西,但是发现没有SDCC头文件,写个工具将 keil 的头文件转成 sdcc 的.闲话不说,上代码. 写的比较脏,别介意.

SDCC标准51头文件不够用么?没搞明白 mowin 发表于 2015-6-13 22:33
SDCC标准51头文件不够用么?没搞明白
有些寄存器没有的。懒得一个一个添加了，干脆一劳永逸。 就一个支持C的单片机，楼主想多了。 就是关键字转换嘛 发现protues 8.9里面内置了一个STC的模型可以仿真的,又不想装keil,放狗一搜搜到这个帖子.
不搞CPP,电脑上连C++环境都没有,花了半个小时现场撸了一套MinGW编译出来试了一下
关键是,不能用啊LZ同学~
自己用c#撸了一个,替LZ把这个坑填了~
同时提供一个预编译过的,把头文件拖上去就行了,需要.net 4.5以上的运行库支撑.
不保证好使,只用了一个STC软件里面导出的头文件做了测试~
