看到51hei的坛子有坛友做的16X16LED汉字显示屏,作为生日礼物表情意,我也想着做一个!以满足动手爱好!
用AT89C52的,驱动电路复杂得不得了,32个三极管,32个电阻啊!焊得头到晕啊!还要个4-16译码电路!!!!!!
幸好有爱情的力量,为那个哥们辛苦为感动!
我呢,有STC12C5A60S2这个单片机的"神器",比AVR的还好.价不贵,才7元/片!有AD,PWM,端口四态,可最大驱动20MA电流!60KB的程序FLASH ROM.爽YY啊.一个简单电路就可以做成16X16的LED了. 8X8的双色是我2元/片淘来的!只用到了红色的!
电路简洁无比,就是一个单片机,四片8*8LED点阵,一个12M晶振,2个30P电容,(12M晶振,2个30P电容,可以省的.,便为了能在线下载,加上去方便下载程序)
电路这么简单,也是受到杜洋老师的影响,我这个还是列驱动,实测电流35MA,运行一个晚上,芯片安全.就不费心思研究杜老师的点驱动了!!!
程序也是学别人的,改了下就能用,C就是好啊!汇编的话,估计没那么方便!
不用那么多了,上图说话!
