Baggus: I always use the following line:

avrdude.exe -p m88 -c usbasp -U flash:w:"cl-osd.hex" -U eeprom:w:"cl-osd.eep"

You might have to change the paths to the files...
This line will flash both flash and eeprom.

I am pretty sure, I can read it on the chip of my G-OSD.
It has "ATMEL MEGA88PA" written on it.

The USBASP do not work in AVR Studio. At least not mine...
But my stk500 and my AVR mkII works.
holy poop

just clicked "continue anyway" in extreme burner with the ATmega88 selected and it worked

was afraid to continue before because i thought it could brick my osd

going to hook it up to a cam and tv right now brb

Yeah, cool Baggus.

Little to much data on the screen for my taste. Have posted my layout earlier, but already changed since then.
Unfortunatly with goggles its not so easy to make a "screenshot".

I do have mine ready to fly now. With RSSI working (for me), altitude above home and a nice screen layout. I added the hex-file, if someone wants to have a look at it.

Baggus: Nice! :-)

Do anybody have an G-OSD that I can buy?
Preferably someone in Europe.
They seem to be back ordered at HK.

Never mind about buying a G-OSD.

The got back into stock now so I ordered a new one!
The donations payed a part of the cost at least.

Wouldnt a E-OSD have been sufficient in your case? As far as I understood you, it is basically a G-OSD with different firmware and of course without the GPS-module?

Parity: Yes, I will work on an extra E-OSD I bought from a friend until I get my G-OSD.
But I like the pots and extra inputs of the G-OSD and soldered cables on the E-OSD might come lose during flight => bad!

Not really software-related, I know, but I would like to know: I had a hard time getting a fix yesterday. Took me more than 20 minutes. Tried to restart after 10 minutes, but didn't help. I don't think I will be so patient, when I actually want to fly.
What is your experience? Manual said somthing like 60 seconds to fix, I am far from that.
How many satellites do you get? I was with (only?) 4 sat yesterday.

Parity: I have seen some problems with fix as well. I think that the gps-module is far from top quality.
I saw somewhere that placing the gps module on some aluminium foil might improve performance.
When I was walking around testing the cl-osd the other week I first had some problems getting a fix but then placed it on top of my car and got a fix right away.

But one test point is not enough to prove anything... :-)

callelj: I really like this project, but there is no information about it - I haven't found any list of features for both OSDs, screenshots or something... I only know it brings a home arrow in the G-OSD.

My question is about E-OSD - is it possible to use it the way the first battery will be displayed as a standard voltage and the second one as a RSSI? I just want to use it this way on my tricopter... I'm sorry I'm too bad in C to find all the informatins inside the source codes... Thanks in advance!

Rastislavko: Yes, it would be possible. But you would have to change the code a little bit and recompile it.

Sorry for bad documentation, will try to work on that.

That leads myself to the question why I did not just use the Batt2 with pot to measure my RSSI instead of using Analog3 and Analog4 to calculate the value
Note: RSSI voltage has to be ripple free. I had to flatten the signal of my 2G4 receiver with a opamp and capacitor to get a flat voltage, otherwise I had values jumping all around.
