Latest firmare version for your OSD

[Alex Villa]

Instructions to update:
-Make sure you have the latest pickit2 software, v2.61. Else download from here
-Carefully follow the instructions on Chapter 10 of this document: http://www.rangevideo.com/docs/rvosd4.pdf. Use the latest firmware for the main board(big board) and the graph board if available.
-Make slight side pressure while the board is being programmed, this to prevent bad contacts and errors because of that.
Warning!
-If there is no new firmware update available for the graph board on your RVOSD version, dont flash it. Because upgrading the graphic board will make your OSD to be locked, and you will have to email Rangevideo to receive your unlock code.
-Upgrading the firmware will overwrite all your settings. You will need to configure everything again after upgrade.

Version 3.05-4.05: Fixed a bug introduced on previous version. Altitude display dont display properly over 256 mts or feets.
Version 3.06: Fixed a bug on the derivative gain, causing GPS only RTH take over to destabilize the plane when derivative gain set to anything but zero.
Version 4.06: Fixed a bug on autopilot bank derivative. Increased maximum plane angle to display coordinates up to 90°. Changed altitude to show peaks under 8mts(26 feets)

Warning!
You have to install the new G5 board before patching this upgrade to the main board. This upgrade will not work with old graphic boards!
Waypoint sequencer is already installed on this upgrade. But only active for USA-Canada area.

For RVOSD G5.0:
Main board: 5.02 Release date 30/June/2011
-Fixed compatibility issue with LRS PPM string
-Fixed absolute current sensor sensibility at low currents
-Internal changes to inertial unit

-Fixed a bug in AHI neutral when set to 90 or 270°.

Main board: Main_5.04S Release date: 20/July/2011
-Fixed instability selecting RSSI levels.
-Added PWM pulse coded RSSI for EZUHF receivers.
-Internal changes to the GPS parser to make it more robust against interference or affected GPS signal levels.

Main board: Main_5.05S Release date: 23/July/2011
-Improved inertial unit compensations

Main board: Main_5.06S Release date: 06/October/2011
-Same changes than Main_5.06uS

Firmware 5.07: Main and graphic board firmware can be found here.

For RVOSD G5.1:

Firmware 5.07: Main and graphic board firmware can be found here.

Pre-release firmware to use a second auxiliary channel:
There is also the option to test an experimental firmware that adds the option to set a second auxiliary channel to select the auxiliary autopilot mode without entering the menu. This firmware has to be flashed to main board only. Provided that you have the latest firmware version on the graphic board. This works for RVOSd 5.0 and 5.1.

Can be found here.

Alex, what is this firmware correcting?
thanks.

I am making this post so users can have all the info about updates in one thread. I am still working on it.

Version 4.04
- Baro height will be used by the autopilot if the altitude is selected for "baro" or "both", GPS height will be used if altitude ladder is selected to GPS.
- Throttle channel no longer goes to full throttle if RC link is lost while you are using the "Fly by wire" stabilization mode.
- I added back the stabilization mode cancel if RC link is lost, so now it will be back to manual mode after RC link lost.
- Removed the virtual fence changing the autopilot mode to "Return to home" if the virtual fence is treaspased.

[Alex Villa]

Main_3.04.hex is the new available update for RVOSD G1, 2 and 3. It has all the same fixes and updates than Main_4.04.hex for RVOSD G4. Only difference is G4 has a menu to setup altitude for baro or GPS.

Thats great Alex Thanks. But what about us that need the SE upgrade?

Alex can you elaborate on these two so I'm sure I understand.

I was not aware that the throttle channel went to full throttle if the RC link was lost while in fly-by-wire mode. It seemed like it would go to cruise throttle as was intended. I don't recall this being discussed but could have missed it.

On the stablization mode if you are using fly-by-wire mode, lose and then regain the RC link will the fly-by-wire mode still be active? Originally it was turned off when the RC link was regained.

Thanks!

[Alex Villa]

On G4 I had made the stabilization mode to resume after RC link lost take over, but someone was landing on 3rd person and switched level flight accidentally, he turned the Tx on and off trying to get control back and nothing, because the new feature. I think on other situations this could be bad. So now RC link lost gets the control back to manual.

Also I added the ability to set the virtual fence for all stabilization modes so if you hit the fence with any stabilization mode active it is changed to RTH. This caused this: http://www.youtube.com/watch?v=R74qY...eature=channel
The user though it was RC link really lost, tried siwtching Tx on and off. But unfortunatly never tried to disable stabilization with the switch.
The RTH flew the plane untill the battery was drained and autolanded 40 feets away. He was lucky there was nothing on the landing path. But I removed this option as well.
And yes there was a bug with RTH setting full throttle if the RC link was lost in FBW mode.
I think I will eventually add this features back, but I have to add also modifications to the graphic firmware so everything gets clear, and even add menus to enable this options. With the defaults set to disabled.

[Gary Evans]

Making one firmware compatable with all applications can as you know get pretty complicated. Another approach maybe could be to have patches available for specific functions and let each user decide on their own configuration. Candidates could be -

1) Maintaining FBW mode after RC loss
2) A altitude or horizontal distance from home to disable the RTH function

Yes I admit it these are my favorite mod's!

[Gary Evans]

The bug in the RTH throttle setting was only in the Gen4 firmware? I tested my Gen3 and it goes to cruise throttle.

[slides]

Yeah ! Understand nothing. So others corresponds about no full throttle after FBW mode - my 3.02 switches to cruise speed. Not understand about virtual fence - RTH switches on after crossing this range at 3.02 firmware ? If so i need no to upgrade to 3.04.

Alex ! Wanna recommend to reprogram idea of FS throttle to not "+" 110%, but to "-" 110%. Because I can get body damage at the ground when test my radio !!! Failsafe is better to set to turn motors off, not maximum throttle.
