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!以滿足動手愛好!
用AT89C52的,驅動電路復雜得不得了,32個三極管,32個電阻啊!焊得頭到暈啊!還要個4-16譯碼電路!!!!!!
幸好有愛情的力量,為那個哥們辛苦為感動!
我呢,有STC12C5A60S2這個單片機的"神器",比AVR的還好.價不貴,才7元/片!有AD,PWM,端口四態,可最大驅動20MA電流!60KB的程序FLASH ROM.爽YY啊.一個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,就是一個單片機,四片8*8LED點陣,一個12M晶振,2個30P電容,(12M晶振,2個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,我這個還是列驅動,實測電流35MA,運行一個晚上,芯片安全.就不費心思研究杜老師的點驅動了!!!
程序也是學別人的,改了下就能用,C就是好啊!匯編的話,估計沒那么方便!
不用那么多了,上圖說話!
