有一个点阵的资料

该LED点阵显示模块采用AT89C52控制。可显示汉字、图形、动画及英文字符等；显示方式有静态、横向滚动、垂直滚动和翻页显示等。单块模块控制驱动12块（最多可控制24块）8X8点阵，共16X48点阵（或32X48点阵），是单块MAX7219（或PS7219、HD7279、ZLG7289及8279等类似LED显示驱动模块）的12倍（或24倍）！可采用“级联”的方式组成任意点阵大显示屏。显示效果好，功耗小，且比采用MAX7219电路的成本更低。,Have a dot-matrix information of the LED dot matrix display module using AT89C52 control. Can display Chinese characters, graphics, animation and English characters, etc.　display has a static, horizontal scrolling, vertical scrolling and page display. Single module control block 12 drives (up to 24 can be controlled) 8X8 dot matrix, a total of 16X48 dot matrix (or 32X48 dot matrix), is a single block MAX7219 (or PS7219, HD7279, ZLG7289 and 8279 and similar LED display driver module) of 12 times (or 24 times)! Can " cascade"　approach the composition of arbitrary large dot matrix display. Show the effective power of small, and the MAX7219 circuit than lower cost.
