OK all...I'm sure this has probably been addressed previously but I haven't found it. I'm having issues with the MinimOSD (latest firmware and all) and a GoPro Hero 3 camera (latest firmware as well). Here's the situation:
So there's my situation. I've come to the end of ideas on where to go from here. Any help or guidance would be greatly appreciated.
Wayne, were you able to resolve your issue? Have you tried using a pull-up resistor on the cable to the gopro?
Yep. The problem was a fried video output channel on the GoPro camera. Instead of getting the required 1 volt peak-to-peak from the video signal, I was getting around 60-70 millivolts. New camera.....no problem. Thanks for responding though. Much appreciated.
well, that's a bummer. Were you able to determine how you fried it? I just got a video transmiter for my gopro and wouldn't want to fry the video output
I have the same problem with my hero 3+ I purchased from 3drobotics. I have read through the responses and I have verified all the connections without the minimum osd and also cant get any video. I never connected any cables from the camera that was not checked and rechecked based on the drawing provided from 3dr. I am unable to get any kind of help from them.( other than they sent me the cable drawing - thanks - ) I never connected the camera to anything before I received the drawing.. does anyone have any idea or should I just send it back. Oh yea the OSD board works fine with the Sony camera. I did notice that it seems to get hot when the gopro is connected. ( warm when the Sony is connected ) !! thanks for everyone's help..
Wayne, I had the same issue and I discovered that the gopro company is updating all cameras and disconecting the usb port; so if u did the update, I'm sorry, but probably you loose your cam for transmission, like me.
I complained to gopro company and explained that it's stupid and bla bla bla....anyway, the gopro technicians didn't know why it happened. Two days ago I bought a new gopro4 black and I didn't updating it and it's working and I didn't replace any cable or transmiter....I hope that 3DR can help us telling withe gopro to reverting this issue..
I'll open a new topic about it.
I hope I could help you.
