Port Finder

This package finds the port name of a desired device.

Package Usage Example

#include <string>
#include <port_finder/port_finder.hpp>

using namespace std;

int main(void)
{
    // Information of the device to be searched
    string port_directory = "/dev";
    string ID_VENDOR = "u-blox_AG_-_www.u-blox.com";
    string ID_VENDOR_ID = "1546";
    string ID_MODEL_ID = "01a9";
    string ID_PATH = "pci-0000:00:14.0-usb-0:1:0.0";

    // Port Finder
    PortFinder port_finder;

    // Finding port name of the searched device
    string port_name = port_finder.find_port(port_directory, ID_VENDOR, ID_VENDOR_ID, ID_MODEL_ID, "NO", false);

    return 0;
}

Note for parameters

• ID_Path: ID_Path should not be used if the device is constantly plugged into different ports. To do this, "NO" must be sent as argument to ID_Path parameter.
• keep_search: If you want to continue searching until the port is found, true must be sent as argument to the keep_search parameter.
