Did anyone read the device orientation in Windows?

Hi, I’m writing a program for a Surface Go 3.

It is working fine, except that ofDoesHWOrientation() returns false even if the device has accelerometers etc.

MS provides an example: Windows-universal-samples/Samples/SimpleOrientationSensor at main · microsoft/Windows-universal-samples · GitHub

Has anyone accessed such sensors under Windows with oF?

Even a command line tool to get the orientation would do, but I haven’t found such. It is tempting to fix the issue by replacing the OS XD

Update (useful reference):

Hi, I’m trying to read the tilt of a Windows Surface tablet and failing.

Is it theoretically possible to compile on MSYS2 code that depends on

#include <windows.h>
#include <sensors.h>
#include <sensorsapi.h>

?

I’m asking because MSYS2 seems (to me) like a Linux based environment running on Windows, so I don’t know if those header files are available.

My code fails to compile with 'CLSID_SensorCollection' was not declared in this scope here:

github.com

hamoid/openFrameworks-windows-device-rotation/blob/main/src/GetOrientation/DeviceOrientationSensorFactory.cpp#L43

      
        
            
            
    if (FAILED(hr)) {
                    OutputDebugString(L"No Sensor");
                }
            
            
} while (false);
            
            
if (pSensor != nullptr && pIDeviceOrientationSensor != nullptr) {
            
            
    ISensorCollection* pSensorCollection = NULL;
                HRESULT hr = ::CoCreateInstance(CLSID_SensorCollection, NULL, CLSCTX_INPROC_SERVER, IID_PPV_ARGS(&pSensorCollection));
                do {
                    if (FAILED(hr)) {
                        OutputDebugString(L"Unable to CoCreateInstance() a SensorCollection.");
                        break;
                    }
                    pSensorCollection->Clear();
                    pSensorCollection->Add(pSensor);
                    // Have the SensorManager prompt the end-user for permission.
                    hr = pSensorManager->RequestPermissions(NULL, pSensorCollection, TRUE);
                    SafeRelease(&pSensorCollection);

Interesting because it doesn’t complain about CLSID_SensorManager…

Any suggestions would be greatly appreciated I have never used a Windows API.
