我汗?。。?！ 給你解釋了不下5遍，你居然還沒(méi)明白。 最后和你解釋一遍，每次發(fā)送一包8個(gè)字節(jié)的數(shù)據(jù)，等待CH372中斷，解鎖之后在發(fā)送8個(gè)字節(jié)的0X00等待CH372中斷。再次解鎖，之后才能發(fā)送下一個(gè)按鍵值。 而不是你上面所寫(xiě)的，你見(jiàn)過(guò)誰(shuí)按鍵是微秒級(jí)的啊？？？？？

大哥啊，原理我也重復(fù)過(guò)了，你們都說(shuō)正確，可現(xiàn)在得看實(shí)際結(jié)果啊，不能剛說(shuō)原理

我已近列出了兩種結(jié)果，一種正常，一種異常，這個(gè)怎么解釋?zhuān)?/p>

呵呵，看樣子你還是沒(méi)理解，這樣吧，你把程序發(fā)到fqb@wch.cn，我來(lái)幫你把程序改好。改好之后麻煩你在回頭看下我們解釋的是否正確。

我們已經(jīng)給你解釋了幾次正確的流程應(yīng)該怎么做。我們也不希望去給你解釋一個(gè)錯(cuò)誤的行為產(chǎn)生的現(xiàn)象。請(qǐng)按照我們提供的流程去做。 產(chǎn)生這個(gè)現(xiàn)象是由于USBHOST發(fā)送IN令牌的時(shí)候?qū)纹瑱C(jī)來(lái)說(shuō)這個(gè)時(shí)間并不是一定在一個(gè)固定的位置。取數(shù)據(jù)有個(gè)時(shí)間差可能會(huì)導(dǎo)致這個(gè)問(wèn)題。一句話，你的流程錯(cuò)誤。

按照我們給你說(shuō)的流程，絕對(duì)不會(huì)有任何問(wèn)題。為什么不能去修改呢？ 這樣你下載一個(gè)軟件叫BUSHOUDN軟件，對(duì)你調(diào)試軟件也有幫助。

哈，這里好多CODE是我寫(xiě)的噢。
