這是一個(gè)復(fù)合HID設(shè)備，用在觸摸i2c的電容觸摸轉(zhuǎn)USB

端口1用來(lái)接收數(shù)據(jù)，端口2發(fā)送數(shù)據(jù)。

現(xiàn)在從端口1發(fā)送數(shù)據(jù)到電腦通過(guò)串口監(jiān)聽(tīng)到39設(shè)備的1好端口收到了數(shù)據(jù)包。

請(qǐng)教一下CH554要怎么從端口1發(fā)送數(shù)據(jù)到pc，讓復(fù)合設(shè)備58收到觸摸數(shù)據(jù)？

Z這個(gè)是WCH廠家的i2c轉(zhuǎn)usb觸摸屏監(jiān)聽(tīng)的數(shù)據(jù)包，是通過(guò)端口2上傳數(shù)據(jù)到pc?，F(xiàn)在不知道58這個(gè)數(shù)據(jù)是怎么來(lái)的，單片機(jī)那邊要怎么做才能讓電腦收到這個(gè)數(shù)據(jù)包。

這個(gè)看起來(lái)像BUSHOUND的顯示問(wèn)題，僅需要顯示39號(hào)設(shè)備的抓包就可以了，實(shí)際遇到了什么問(wèn)題呢。

現(xiàn)在pc端能夠識(shí)別到設(shè)備，觸摸沒(méi)有反應(yīng)。應(yīng)該是pc沒(méi)有識(shí)別到有效的HID的數(shù)據(jù)包。

WINDOWS 對(duì)觸摸屏么有反應(yīng)，但是我插到我一個(gè)linxu設(shè)備板子上卻能夠工作，證明發(fā)送的數(shù)據(jù)包還有usb枚舉部分應(yīng)該沒(méi)有問(wèn)題。但是windows不能工作不知道是哪里的問(wèn)題，感覺(jué)還是數(shù)據(jù)包的問(wèn)題。

當(dāng)我發(fā)送數(shù)據(jù)長(zhǎng)度為64的時(shí)候，抓到的數(shù)據(jù)報(bào)，就能看到多了一個(gè)設(shè)備的數(shù)據(jù)包，如圖49設(shè)備。不知道什么原因。

可以把對(duì)應(yīng)的描述符相關(guān)內(nèi)容發(fā)出來(lái)看下，報(bào)告描述符會(huì)上報(bào)數(shù)據(jù)的可以，可以檢查下發(fā)送的數(shù)據(jù)格式是否和報(bào)告描述一致

從描述符格式和數(shù)據(jù)來(lái)看，可能是最后Report ID為4的這個(gè)描述，第二個(gè)字節(jié)中包含了Usage (0xFF)的一位，會(huì)不會(huì)是需要特定的驅(qū)動(dòng)程序才能驅(qū)動(dòng)起這個(gè)屏幕？可以找個(gè)類(lèi)似描述符的可以在WIN上使用的樣品抓包對(duì)比下看看。

數(shù)據(jù)的發(fā)送也是模仿原來(lái)觸摸屏的通信協(xié)議發(fā)送的數(shù)據(jù)，在linxu板子上可以工作，按理說(shuō)協(xié)議應(yīng)該沒(méi)有問(wèn)題。就是不知道在windows上為啥不行。除了從端口1上傳數(shù)據(jù)外還要做其他什么步驟沒(méi)有做？
