在打开设备后的具体调用代码如下

    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() << "发送数据\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() << "读取失败\n";

    }

    delete[] data;

    delete[] recv;

当执行到 CH347StreamI2C 函数后会导致程序异常崩溃，请问会是什么原因引起的？

您好，可将

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

修改为试一下

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