正文摘要:

近期得到一塊16x64的LED屏幕板子，板子上的集成電路有，8塊74hc595、一塊74hc245，一塊74hc123，一塊74hc367、2塊hc74138.參考網(wǎng)上的接口定義和驅(qū)動，能夠點亮，但出現(xiàn)一下問題：只送一個字的數(shù)據(jù)時，第一個字顯示正 ...

回復

厲害啊，欣賞欣賞。謝謝

樓主的思路好啊。通過調(diào)整，把板子搞好了，值得借鑒。向樓主學習。

ICi是STC5608，晶振18。432

非常感謝你，經(jīng)過實驗，原來是板子上的74hc123工作不正常引起的，可能是我的程序達不到原來板子的刷新頻率，導致74hc123工作不正�！，F(xiàn)在把板子上的74hc123去掉，把一塊138的6腳接vcc，另一塊138的4腳接地，讓138正常工作，顯示就正常了。

需要審核所，我以為沒發(fā)得起，反復發(fā)了幾次，
這程序是以前的，很多對你沒什么用，比如EEP串口通信等，當時編得不是很好，你取你需要的部分就成

你一次將4個字的數(shù)據(jù)發(fā)完再鎖存就OK了

一次將4個字的數(shù)據(jù)發(fā)完,就會有幾行不亮，字顯示不全。
