As some people around here, i'm experiencing pb with my minimosd, latest release...
Everything was working fine.
But for no reason, i can't display any data overlay anymore on my image.
I can see the camera view through the osd, but i 've no information at all.
It may come from the fact that i connected unfortunately the usb in the same time as the osd on my apm... Could that fried my osd ?
I reflashed everything and sent back the charset with a well powered usb port + alim on the other side of the osd.
All the best,
Thanks for your help.
Nope. If i disconnect the camera, i got nothing at all....
I happened to order a new minimosd. But if i can troubleshot this one i will be quite happy !
I have the same problem
There's a long thread here which has some solutions but I have the same problem still.
The max7456 chip is quite fragile. As far as i understand, it can easily be killed by slight voltage differences between the analog and digital grounds (or Vcc) for instance.
I already fried too boards... but it is not very difficult to repair it by replacing the MAX chip (you can order a couple of these chips as free "samples" on Maxim site). You can find some more details here:
