Update on 2025-07-25 07:09:21

Function description: Demonstrate Device control operations

| This example is based on the C++low level API for demonstration

Get device list

// Create a Context.
ob::Context context;

// Query the list of connected devices
auto deviceList = context.queryDeviceList();

Get device and output device information

if(deviceList->deviceCount() > 0) {
    if(deviceList->deviceCount() <= 1) {
        // If a single device is plugged in, the first one is selected by default
        device = deviceList->getDevice(0);
    }
    else {
        device = selectDevice(deviceList);
    }
    auto deviceInfo = device->getDeviceInfo();
    std::cout << "\n------------------------------------------------------------------------\n";
    std::cout << "Current Device: "
                << " name: " << deviceInfo->name() << ", vid: 0x" << std::hex << deviceInfo->vid() << ", pid: 0x" << std::setw(4) << std::setfill('0')
                << deviceInfo->pid() << ", uid: 0x" << deviceInfo->uid() << std::dec << std::endl;
}
