Hello.
I use a minimosd configured with this tutorial : https://librepilot.atlassian.net/wiki/plugins/servlet/mobile?contentId=7274504#content/view/7274504

Perfectly work but..  in black and white lol. When i connect directly video output cam and video input transmitter i have colors 
I don't have see a opion into ArduCam.
Thanks

And my rssi is alway 100%, with and without my radio turned on.
I have test with rssi raw enable and without same result.
I have a frsky l9r receiver. Just single wire between l9r rssi output and minimosd rssi input.
Whats rong?

The black and white problem is very probably a difference between NTSC and PAL video standards.  It sounds like the OSD needs to be configured for the other video standard if that is possible.

RSSI is still high even with transmitter switched off?

My cam send me a pal video and i have select Pal into ArduCam.
This night i try to select ntfs for see the different.

For know my rssi power i just turn on my quad i see into video return the % rssi. Stay always at 100%.
But maybe firmware is rong because i don't remenber if i haved choose LP_all_from_revo1110.hex or LP_all_from_revo+analogRSSI....
My rssi wire is like this picture. I need to choose firmware pin1 or pin3?
Thanks for all your answer so usefull.

I'm not an OSD expert.  @f5soh will probably be by to shed some light on that.

If you have the small OSD hardware version (MicroKvteam) you need the LP_All_From_Revo1110+AnalogRSSI_MicroKvteam_pin3.hex firmware.

Ok i have just finis my day's work  so i try it and i send the result

[tinou]

 
I have test with this firmware with and witout select "RSSI Enable Raw" and .... RSSI always 100%.
I have test the anotther firmaware same resul.
I have controled +3.41V RSSI outpout when radio is turned on and 0.28V when is off.
I have check on the minimiosd intput pin!
I think now there are no solution for fix my RSSI and colors problem so i need to buy a new one.
Witch external osd can me advoice for my revo? Something like minimosd but better quality if it's possible.
Thanks for all

[tinou]

Maybe i need low pass filter?

[f5soh]

There is two hardware compatible for OSD, the full sized and the micro OSD.
Quality will be the same as the schematic and components are similar.

Video without colors looks like video standard mismatch PAL, SECAM...

[tinou]

Ok i buy a new one.
Answer in 3 weeks

[f5soh]

Buying a new one will not change the result about colors.

[tinou]

Euh.. why? You have said mismatch between Pal and sepal. But my runcam is on Pal and i just can choose between Pal and NTSC with ArduCam.
It's my cam the problem?

[TheOtherCliff]

I think the idea was that buying a new one of the same brand/model will not fix it.  You would have to buy a different brand/model of OSD and try to match all components to either NTSC or to PAL when you are buying and configuring.
