说明：  上面的程序可以用于,PIC单片机,也可以用于430单片机,而且只要改变一两个数字即可,本人原创.而且在网上还没有发现哪位网友想出这种简单的方法.望版主多加分.放上来的程序都已调试通过,可以直接使用.
(Above procedures can be used, PIC microcontroller, can also be used for 430 single-chip, but as long as the two figures one can change, I am original. But also in the online users who have not yet found ways to come up with such a simple . look more points moderator.放上来debug procedures have been adopted, can be used directly.)
