CH347StreamSPI4函數(shù)與SPI從機(jī)通信時(shí)?偶爾會(huì)出現(xiàn)函數(shù)不返回阻塞導(dǎo)致進(jìn)程卡死的現(xiàn)象。
此時(shí)只有拔掉CH347的USB口才能解決卡死問(wèn)題（函數(shù)可直接返回錯(cuò)誤）

程序已經(jīng)在CH347OpenDevice后設(shè)置了超時(shí)

CH347SetTimeout(mDevIndex,500,500);

卡死后的頁(yè)面、LOG日志、設(shè)備管理器

您好，在通信異常時(shí)如不動(dòng)硬件重新開(kāi)關(guān)軟件是否可以恢復(fù)？如開(kāi)關(guān)不能恢復(fù)，重新上電或插拔USB可恢復(fù)，則因?yàn)閁SB信號(hào)傳輸不穩(wěn)定產(chǎn)生了異常的可能性較高。

需檢查PCB設(shè)計(jì)，USB使用端子以及線纜情況。CH347是高速USB2.0轉(zhuǎn)接芯片，因此USB的設(shè)計(jì)和線纜需要遵循協(xié)議規(guī)范。

您好，按您說(shuō)的嘗試了，強(qiáng)制關(guān)閉軟件->重啟軟件，可以正常通信，無(wú)需重啟硬件。這似乎不是硬件問(wèn)題
