看到51hei的壇子有壇友做的16X16LED漢字顯示屏,作為生日禮物表情意,我也想著做一個(gè)!以滿足動(dòng)手愛好!
用AT89C52的,驅(qū)動(dòng)電路復(fù)雜得不得了,32個(gè)三極管,32個(gè)電阻啊!焊得頭到暈啊!還要個(gè)4-16譯碼電路!!!!!!
幸好有愛情的力量,為那個(gè)哥們辛苦為感動(dòng)!

      我呢,有STC12C5A60S2這個(gè)單片機(jī)的"神器",比AVR的還好.價(jià)不貴,才7元/片!有AD,PWM,端口四態(tài),可最大驅(qū)動(dòng)20MA電流!60KB的程序FLASH ROM.爽YY啊.一個(gè)簡單電路就可以做成16X16的LED了.  8X8的雙色是我2元/片淘來的!只用到了紅色的! 
   電路簡潔無比,就是一個(gè)單片機(jī),四片8*8LED點(diǎn)陣,一個(gè)12M晶振,2個(gè)30P電容,(12M晶振,2個(gè)30P電容,可以省的.,便為了能在線下載,加上去方便下載程序)
   電路這么簡單,也是受到杜洋老師的影響,我這個(gè)還是列驅(qū)動(dòng),實(shí)測(cè)電流35MA,運(yùn)行一個(gè)晚上,芯片安全.就不費(fèi)心思研究杜老師的點(diǎn)驅(qū)動(dòng)了!!!

  程序也是學(xué)別人的,改了下就能用,C就是好啊!匯編的話,估計(jì)沒那么方便!

不用那么多了,上圖說話!
