51单片机内部资源应用

Question

那里有‘51单片机内部资源编程的资料’，初级

Answer 1

什么叫内部编程资源啊。没这个概念啊。要是C的话你可以用中断服务函数在相应的中断号匹配的情况下使用内部定时器/计数器，外部中断，串行中断来产生中断请求，在中断服务程序里面就能看到是哪个资源触发了中断啊。51就那么点内部资源 2个定时器 1个串口 2个外部中断，就这么点东西啊，基础的51很简单的你看看pic 或者其他的单片机你就知道资源太多的时候那种小小的崩溃感觉了^_^。
楼上的兄弟说的对学单片机还是要懂汇编的不然以后很麻烦！！

Answer 2

你是不是一学51就学C语言了?
你应该先学汇编的,这样你就懂他的内部资源,底层的原理了.以后学C51就更容易了(建议).
给你看下C51对51单片机的内部资源定义:
