arm C语言 s3c2410a [复制链接]

对arm进行从语言开发时 怎么知道C语言中对寄存器的定义，头文件中有么，去哪里找s3c2410a头文件
初学arm请高手指教

我认为网上应该很多，要不结合datasheet自己定义？

shenjl

随便在网上找个例程里就有
如果不闲麻烦的话，也可以自己写，呵呵

去UBOOT,VIVI里有现成的，网上一搜一大把！

CPU的寄存器不方便在C里面访问,外围的寄存器可以很方便的用C访问.

zjuxuliyan

通常在.h和.inc的头文件里边定义。

可以看一下别人的代码，比如网上的一些BOOTLOADER。

你可以看看三星自己用ADS写的那个测试程序，大部分功能都用到了，或者上网下载一些demo吧

mingdi

可以用别人的看看 自己写挺麻烦的

与缘相伴

急需资料，软件，例程。。。
大家帮帮忙
