I've just released an alpha kernel driver for the Z800 HMD. Full details at eMagin's 3dvisor.com forum or grab it from my website at: http://antimass.org/z800 From the README in the package: Z800/X800 Linux Kernel Driver v0.6 About: A kernel driver for the eMagin Z800/X800. Most of the USB packet info came from eMagin's publically released source code for their EMADevice SDK. WARNING: This is ALPHA software. It might destroy your system and/or your HMD. You try this software at your own risk. Don't come crying to me if your system/hmd stops working. You've been warned. Requirements: - Z800/X800 HMD (duh) - Kernel 2.6.17 or greater. It may work with an earlier kernel, but I haven't checked. Success/failure reports are welcome. - Kernel support for loadable modules Installation: The Short version: make make install make load The Longer Version: 1) Run "make". This will create the kernel module. 2) Run "make install". This will copy the kernel module into your system's /lib/modules/2.6.??/extra directory with the module name "z800.ko" 3) Run "modprobe z800". This will load the module into the kernel. Check your dmesg file. If all goes well, it should successfully see your Z800. If not, send me the report. Testing: I've included a small test program to show how to control the Z800. Run "make test" and then "./z800Test". It should print out the Z800's firmware version and wake it up (note: the led on the control base may still be blinking, but the HMD's screens should be active ). TODO: - add proper locking in the driver - use wait_event_interruptable instead of looping - add missing controls ( 3DFLIP, etc ) - add EEPROM property programming (offset, gain, etc ) - fix dev/z800:0 location. Use "/dev/z800/0" instead for better multi z800 support - only activate the read_urb when needed, not constantly - add hmd tracking!! Need usb info for that. - get it into the linux kernel mainline - many others... Known Bugs: - once 3D Stereo is enable, it can't be disabled until the Z800 is disconnected. Don't know why. - even after the Z800 is woken up, the led on the controller is still flashing, even though the HMD's screens are active Author: Adam King Changelog: 0.6 [ 2006/10/27 ] - Initial Alpha Release. - Supports: GET_FIRMWARE, CYCLEBRIGHTNESS, KEEPALIVE. SET_ENABLE_3D, SLEEP (no support in fw) (Message edited by aking on October 28, 2006) |
