Beispiel für Force Feedback

Dieses Beispiel zeigt, wie man die CPP HaplyHardwareAPI benutzt, um die Haply Hardware in einem Force-Feedback-Modus zu steuern. Ein vollständiges Beispiel finden Sie am Ende der Datei, aber die wichtigsten Schritte sind:

Fügen Sie die erforderlichen Kopfzeilen ein

#include "HardwareAPI.h"

Suchen Sie das Gerät und öffnen Sie die Verbindung

std::vector ports =
            Haply::HardwareAPI::Devices::DeviceDetection::DetectInverse3s(); // List all the available devices
Haply::HardwareAPI::IO::SerialStream serial_stream(ports[0].c_str()); // Open the connection to the first device found
Haply::HardwareAPI::Devices::Inverse3 inverse3(&serial_stream; // Create the device object
Haply::HardwareAPI::Devices::Inverse3::DeviceInfoResponse response_to_wake = inverse3.DeviceWakeup(); // Get the device info

Senden Sie den Force-Feedback-Befehl

// In a loop
while(True) {
    Haply::HardwareAPI::Devices::Inverse3::EndEffectorForceRequest request;
    // x, y, z forces in N
    request.force[0] = 0.0;
    request.force[1] = 0.0;
    request.force[2] = 0.0;

    Haply::HardwareAPI::Devices::Inverse3::EndEffectorStateResponse response = inverse3.EndEffectorForce(request);
    // Print the position and velocity
    printf("Position: %f %f %f\n", response.position[0], response.position[1], response.position[2]);
    printf("Velocity: %f %f %f\n", response.velocity[0], response.velocity[1], response.velocity[2]);
}
