用中断的方式控制lcd的显示，单片机仍然是h83664十六位单片机。此程序包含单片机的接口的配置以及各种写lcd的子程，使用中断来控制lcd顺序显示A－Z，当然，可以换成其他的显示内容，由于接口程序已经编好，只需要把要显示的内容改一下就可以实现其他内容的显示-With interruption control lcd display, single-chip is still 16 Singlechip h83664. This procedure includes the configuration of single-chip interface and a variety of writing a sub-lcd-way, the use of interrupt to control the order in lcd display A-Z, of course, can be replaced by other display content, as a result of interface procedures have been developed only to To display the contents of change can be achieved about the display of other content
