Good news!
The beauty of this community is on the collaboration. This new firmware proves it.
I have the pleasure of announcing that "ArduCAM OSD" and "MinimOSD-Extra" teams are now working together to make MinimOSD better and better.
I've been planning this fusion with Gábor Zóltan and Pedro Santos and we've started a nice friendship.
We spend the latest days merging and retouching everything to improve your experience with the new firmware. The Wiki was also updated for matching the new resources.
What's up?
You'll se all those awesome improvements from MinimOSD-Extra as well as improvements we made together.
The latest one is the new auto detection and updating of the EEPROM mapping .
From now on both OSD Firmware and ArduCAM OSD Config Tool will share the same internal signature.
So, both will detect the need for an EEPROM remapping preventing from loading or saving truncated data.
After a firmware upgrading the OSD Config Tool will detect an outdated mapping updating it automatically.
If you update your firmware by other way, the new firmware will alert you on screen and the Config Tool will repair automatically before you load anything from the EEPROM.
Update your MinimOSD right now. The most important: Have fun!
Important NOTES:
- After install the new "ArduCAM OSD Config Tool" remember that you need to update the Character Set. A new one is available on the install folder. From now on it will be always there as "OSD_Charset.mcm".
- Both sides of the MinimOSD need to be powered during a Character Set updating. Max7456's internal memory is really picky about voltage level during a charset update.

Ive tried using a battery. Ive used a 5v UBEC, a 2S and a 3S Lipo to the VI/O pins and still, I get a fuzzy... ???
You can use the board like that with no battery on the second stage. However, when updating the charset you have to use a battery there even with the two stages tied. If not, the internal memory of the 7456 wont record the chars properly.
I got it from 3DR. I soldered the two jumpers to allow both sides of the board to be run from the 5v input on the UART side. My 12v are not connected to the board in any way as shown here (http://code.google.com/p/arducam-osd/wiki/How_to_start_minim) on the bottom picture. I saw where you said it was ok to attach a battery to it even if the jumpers were soldered, but it hasnt worked thus far. Im still getting fuzzy characters after connecting the FTDI cable and battery.
@Jamie, you said: "I have the board jupmed to bypass the 12v on the V/in-V/out."
What do you mean with "bypass the 12V"? Could you explain it better?
Is that a clone or a 3DRobotics one. Many many guys are fighting this issue on MinimOSD clones.
So, Ive tried to update the character set, and my characters are all fuzzy. I have tried multiple times with a 5v source attached to both ends of the board and still no success. I have the board jupmed to bypass the 12v on the V/in-V/out. Ive tried it without the battery connected on the video side.. Im at a stand still trying to get my characters right. Help
Sandro,
I have already applied the troubleshooting steps from the link you posted after discovering the issue of the overlay looking fuzzy and not well formed when I first discovered that it wasn't working. I've checked the voltage from the laptop USB, and it is supplying at least 5 volts.
@Francis. Looks like it's a charset update problem.
Did you check the troubleshooting session? (Video overlay presenting fuzzy and not well formed chars)
Yes, I have connected the video output from MinimOSD directly to monitor during the course of my troubleshooting to get to the root cause.I get live video feed with no problem.
Like I said in my post that the HUD did show up initially, but it did not show everything and the characters looked faded.
This is when I attempted to reflash the MinimOSD with the firmware and updated the chartset. Every time I hooked everything up to check the HUD, the HUD did not display all of the characters completely (many were missing) and they appeared faded.
I repeated this activity about 10 times with the same results; then the HUD stopped appearing completely...
LOL... Ok...
Using the following:
Nanotech 3s 1000mah lipo to power the FPV camera and video transmitter (1.3ghz 150mw)
Powering the APM 2.5 with the 3DR power module, using 4s 3000mah lipo .
MinimOSD is connected to the APM 2.5 per the diagram, using the recommended wire cable from DIYDrones store
I guess assuming it is a 12v lipo, I would want to know if you are powering APM with it too, if so, some ground loops start cropping up in my opinion.
