標題: LED點陣屏調試手記。80X16點陣。
       今天在柳州的舊貨市場淘到一塊80X16的點陣屏。老板開價25塊，但是點陣屏的板子很臟，而且PCB上的印制線也有被刮斷的線，需要維修才能使用。經過一番討價還價，以18塊錢成交。從外觀上看，這是一塊雙色屏，接口也是主流接口，信號線分別有ABCD四根行選擇線，DR、DG兩條點陣數據線，分別是紅點陣數據和綠點陣數據。三根控制線，分別是CLK,STB,OE。和常見的屏是一樣的�；貋碇�后就對這塊屏進行清洗，晾干。吃完飯之后就開始進行調試和驅動程序的編寫。因為上個星期買到一個小LED點陣已經調試成功，所以受前一次經驗的影響，讓我走了一個大彎路。實在是不應該，足足浪費我2-3個小時。
        首先說說原來的小點陣芯片情況：小點陣使用2片138做行選擇譯碼，595做控制輸出，當然前面還有74HC245做信號的緩沖。小點陣屏只要接上電源，并將OE拉低，點陣即可點亮。隨后就可以依次進行ABCD\SDA\SCK\STB的信號調試了。小屏的調試過程中還是很順利的。在后來的驅動程序編寫中雖然有些困難，但是依然較為順利的完成了。
        再看看這次的大點陣屏：采用的芯片基本一致，也是138+595+245，但是這塊屏上多了一塊74HC04，經過觀察，發(fā)現該74HC04是與譯碼芯片138相連的。因此猜測是用于信號整形，應該沒有太多的不同。
        首先是修復受損的PCB導線。用砂紙輕輕打磨阻焊層，然后用剪下的電阻管腳連接斷裂處，再用萬用表檢測連通情況確認修復成功后給打過補丁的地方封上硅膠保護。修復完成后按原方法給屏接上電源后，拉低OE，屏不亮。不管OE接高電平還是低電平，屏始終不亮。暈倒了。于是懷疑是不是還有線沒有補好，就又回頭花了10分鐘尋找，無果。于是懷疑該屏是不是被雷擊過，遂拆下信號緩沖芯片74HC245進行測試，結果沒有問題，又將74HC04拆下測試，也沒有問題。再將其焊回電路板。這一拆一試就花了我一個小時的時間，因為我沒有熱風槍，用電烙鐵堆焊拆貼片的芯片是比較麻煩的。再次懷疑PCB板有霉斷的地方，又用萬用表檢測，花去20分鐘。無果。于是進入盲試階段，將信號線全部接到輕觸開關上，隨意的按動開關。起初按動的速度比較慢，屏沒有反應，后來有一次不經意的快速按動了一下按鈕，屏閃了一下。黑黑，這讓我很興奮。仔細一看，原來按動的是D信號線，但再次按動D，屏也不閃。結果快速的按動D信號線（即快速的給D發(fā)送0,1電平），屏跟著閃爍起來了。倒塌了，難道這個屏對于慢速的掃描信號不認同的，之后行掃描頻率達到一定值時才允許通過嗎？馬上寫一個程序測試。
void main()
  {
  speed=25;
  while(1)
    {
P0--;
delay(speed);
if(KEY==0)
   {speed++;}
if(KEY2==0)
   {speed--;}
}
  }
        果然不出所料，當ABCD掃描頻率低時，屏不工作，隨著掃描頻率的增加，LED屏開始隔行點亮，當頻率在20多HZ以上時，LED逐行點亮了。
        此時再回頭看看74HC04的外圍電路不像我們常用的都是接數字邏輯元件，而是接了兩顆貼片的1N4148,電阻，電容等元件。原來這個74HC04跟外圍元件構成了觸發(fā)器，當頻率不足時就會關閉138的輸出，屏自然不亮了。
        接下來開始測試CLK\SDA\STB\RED信號，都很順利，最后測試GREEN信號時發(fā)現不起作用，這是為什么呢？原來雖然點陣用的是雙色的點陣，但是電路板上的另一串控制綠色點的595并沒有焊接，所以就沒有綠色了。于是想用鑷子手動給8X8點陣加電壓點亮綠色的點，卻怎么也點不亮，仔細觀察8X8的點陣發(fā)現雖然每顆LED里面都有3個電極，但是實際上只安裝了一顆LED管芯，倒塌了�？磥磉@塊屏沒有什么神秘之處了。緊接著就開始程序的移植，把原來驅動小點陣的程序修改修改，就成功的驅動了這塊點陣。在程序上倒是沒有費太多的周折。
        由于這次過于相信自己的經驗而導致浪費了大量的時間，這確實不應該，希望有玩LED點陣的朋友不要犯同樣的錯誤了。
