点阵实物程序(16-32两块级联程序)

/*******************************************
程序名称：2个点阵模块从右往左移动显示
外部参数说明：
单片机选型：本程序必须使用RAM为128以上的单片机，建议使用STC89C52 STC89C**,STC90C*等12T的单片机
            如果使用的是STC12C5A*,STC11F*等1T的单片机，需要修改中断定时参数跟左移动的延时。
			本程序可以使用AT89C51 AT89C52 AT89S51 AT89S52等RAM只有128的单片机。

晶振参数：使用12M以上的晶体。建议使用24M以上的晶体，晶振频率越高，显示字不会出现闪烁感。
          如果使用24M以下的晶体，如果是STC的芯片，建议打开6T(双倍速)功能。
          
端口定义：模块的A插针接单片机的P1.4，模块的B插针接单片机的P1.5，模块的C插针接单片机的P1.6
          模块的D插针接单片机的P1.7，模块的LATCH插针接单片机的P1.0
		  模块的CLK插针接单片机的P1.1，模块的DI(程序里面标的是DA_port)插针接单片机的P1.2
		  模块的G(程序里面标的是EN_port)插针接单片机的P1.3
