Function Documentation

arduino_get_fusion_pose()

static void arduino_get_fusion_pose ( struct arduino_device *  ad, enum xrt_input_name  name, struct xrt_space_relation *  out_relation  )

static

Todo:

assuming that orientation is actually currently tracked.

References m_imu_3dof::rot.

arduino_read_one_packet()

static bool arduino_read_one_packet ( struct arduino_device *  ad, uint8_t *  buffer, size_t  size  )

static

Reads one packet from the device,handles locking and checking if the thread has been told to shut down.
