用的是這個代碼。

編譯正常。能正常識別到ttyCH343USB0.

發(fā)數(shù)據(jù)的時候會出現(xiàn)多出2個數(shù)據(jù)。

這是什么原因?qū)е碌?。而且每次第一次插上，只要直接通信，都會報ch343_update_status - unknown status received:len:10, data0:0xa1, data1:0x20這個。后續(xù)不會報。但是發(fā)數(shù)據(jù)就很奇怪

您好，看您發(fā)的是V1.6的老版本驅(qū)動，麻煩下載安裝最新的CH343 Linux驅(qū)動，驅(qū)動鏈接：https://github.com/WCHSoftGroup/ch343ser_linux。?

下載了最新的驅(qū)動后，解決了發(fā)送數(shù)據(jù)出錯的問題。在設(shè)備插上后，第一次對ttyCH343USB0進行操作(配置或者使用默認配置進行數(shù)據(jù)發(fā)送)的時候會報錯。但是后續(xù)操作并沒有受影響
