    在做项目(工程)的时候,我们经常要用到比较多的按键,而且IO 资源紧张, 于是我们就想方设法地在别的模块中节省IO 口,好不容易挤出一两个IO 口,却 发现仍然不够用,实在没办法了就添加一个IC 来扫键。一个IC 虽然价格不高, 但对于大批量生产而且产品利润低的厂家来说,这是一笔不菲的开支! 那,我们能不能想到比较好的扫键方法:用最少的IO 口,扫最多的键?可以吗?-Doing the project (engineering), we often use the relatively large number of keys, and the IO resource constraints, so we are trying to save in another module IO ports, finally out of one or two IO ports, only to find is still not enough there is really no other way to add an IC to sweep on the keys. Although the price of an IC is not high, but low profits, high-volume production and product manufacturers, this is spending a lot of money! That, we can not think of a better scan key method: with a minimum of IO ports, scan Most of the keys? OK?

  • 鉴于MCS
    鉴于MCS-51系统只提供“二级中断嵌套”,提出扩展51系统中断优先级的纯软件方法。其利用51系统内建的中断允许寄存器IE和中断优先级寄存器IP,通过屏蔽字机制来实现;以C51的形式,给出这种扩展方法的函数库实现,为该方法的使用赋予友好、简洁的用户接口。-Given MCS-51 systems only provide "two interrupt nesting," expanded 51 priority system interruption of pure software. The use of 51 built-in system allows interruption Register IE and priority interrupt register IP, through word shielding mechanisms to achieve; C51 in the form of this expansion is the way to achieve functions, methods for the use of empowerment friendly, simple user interface.
