Detailed Description

Driver for a Sample HMD.

Does no actual work. Assumed to not be detectable by USB VID/PID, and thus exposes an "auto-prober" to explicitly discover the device.

See Writing a new driver for additional information.

This device has an implementation of xrt_auto_prober to perform hardware detection, as well as an implementation of xrt_device for the actual device.

If your device is or has USB HID that can be detected based on USB VID/PID, you can skip the xrt_auto_prober implementation, and instead implement a "found" function that matches the signature expected by xrt_prober_entry::found. See for example hdk_found. Alternately, you might create a builder or an instance implementation directly.

Function Documentation

◆ sample_create_auto_prober()

struct xrt_auto_prober * sample_create_auto_prober ( void  )

#include <drivers/sample/sample_interface.h>

Create a auto prober for a Sample HMD.

References xrt_auto_prober::destroy, xrt_auto_prober::lelo_dallas_autoprobe, and U_TYPED_CALLOC.

◆ sample_hmd_create()

struct xrt_device * sample_hmd_create ( void  )

#include <drivers/sample/sample_interface.h>

Create a Sample HMD.

This is only exposed so that the prober (in one source file) can call the construction function (in another)
