在打開設(shè)備后的具體調(diào)用代碼如下

????UCHAR?*?data?=?new?UCHAR[128];

????UCHAR?*?recv?=?new?UCHAR[128];

????ULONG?i?=?0,?send_len?=?3,?recv_len?=?6;

????data[0]?=?0x55;

????data[1]?=?0x07;

????data[2]?=?0xC2;

????qDebug()?<<?"發(fā)送數(shù)據(jù)\n";

????this->CH347I2C_Set_IM(this->DevIndex[this->ui->CBX_DeviceList->currentIndex()],?0x01);

????//if?(this->CH347StreamI2C_IM(this->DevIndex[this->ui->CBX_DeviceList->currentIndex()],?3,?data,?64,?recv))?{

????if?(this->CH347StreamI2C_IM(i,?send_len,?(PVOID)data,?recv_len,?(PVOID)recv))?{

????????qDebug()?<<?"recv:?"?<<?recv?<<?"\n";

????}?else?{

????????qDebug()?<<?"讀取失敗\n";

????}

????delete[]?data;

????delete[]?recv;

當(dāng)執(zhí)行到 CH347StreamI2C 函數(shù)后會導(dǎo)致程序異常崩潰，請問會是什么原因引起的？

您好，可將

if?(this->CH347StreamI2C_IM(i,?send_len,?(PVOID)data,?recv_len,?(PVOID)recv))

修改為試一下

if?(this->CH347StreamI2C_IM(i,?send_len,?data,?recv_len,?recv))
