現(xiàn)在打算用CH554G做一個轉(zhuǎn)接板，需要驅(qū)動XR21V1410芯片，找了倒程只有PL2302,CH340,CP2012的，不知道XR21V1410如何設(shè)置串口參數(shù)，是否可以提供解決方法？怎么組SETUP包，應(yīng)該按什么樣的順序發(fā)送SETUP包？

如果是通過USB通訊的話，可以先接入電腦，通過電腦端USB抓包工具看一下操作流程。然后單片機模擬這個流程操作USB設(shè)備。

有沒有什么文檔可以說明這個過程如何分析操作的？現(xiàn)在用Bus Hound 抓包也不會看，有點頭大

自己搞定了，因為自己的需求很簡單，就是透傳USB口和串口的數(shù)據(jù)，9600的波特率，停止位-1，奇偶校驗-無，數(shù)據(jù)位-8。

還是看芯片的規(guī)格書，不需要插電腦上用USB數(shù)據(jù)抓包，用的原廠的例程，然后找到芯片的PID,VID，再按著例程的驅(qū)動CH340的方式來寫匹配PID,VID,匹配上了后設(shè)置波特率，根據(jù)規(guī)格書來組SETUP包，其中發(fā)SETUP包的時候，剛開始用FOR循環(huán)發(fā)會有問題，后面改成一條條好就可以，花了很多時間來了解USB的相關(guān)內(nèi)容，其實例程已經(jīng)做好了很多前面的工作，只要自己組SETUP包，然后發(fā)送就可以正常運行起來了。參考了這個文章的思路http://www.findthetime.net/bbs/thread-72287-1.html
