MinimOSD in DIYDrones Store!

Hello guys!
I'm very happy to tell you that the MinimOSD is now in stock in the DIY Drones store!
3689439887?profile=originalAnd more: It goes with a nice customized CharSet and an open source OSD firmware already flashed! ;)
The firmware is Arduino compatible and it uses the original APM MAVLink messages to bring out with some nice features.
Here you can see the Artificial Horizon being tested on HIL side by side with the XPlane AH gauge.

Let me talk a bit more about the firmware that goes flashed on the board:
The current open sourced OSD implementation is part of the ArduCAM OSD project which has support from all the DIYD Dev Team.

The requested APM MAVLink messages are grabbed, translated and it's displayed pretty fast.
But... why it supposed to be fast?
Firstly, the OSD class descends from BetterStream from Mike Smith, which turns it able to format and print better than the Arduino's avr-libc variant does.
Second, the CharSet was rearranged to match the ASCII table. It eliminates the need for a "translation" layer.
There is also a smart way to write individual panels with less SPI transactions (that is conventionally used only to write the full screen at once).
The MAVLink parsing uses a reduced number of buffers, which fits better m328p's resources.
Those things above improves considerably the OSD job.

Our friend Jani already wrote the EEPROM routines to make it configurable. So, it has the base for an external configuration tool.
There is much more work to be done for adding functions and improve it.
We're pretty sure that it will be improved a lot in the hands of the awesome DIYD comunity.

Well, let's talk about features:

MinimOSD is able to work attached to the ArduPilot telemetry port in two modes:
1 - as master i.e. requesting rates of all required messages from APM (both TX and RX from OSD board are connected);
2 - as "sniffer" i.e. just listening to all the messages requested from the GCS (only TX from OSD board is connected).

The firmware auto-detects PAL or NTSC and adjusts the panels.
Until now it has this panels:

  • MAVBeats pulse
  • Altitude
  • Speed
  • Battery voltage
  • Battery Remaining
  • Throttle
  • Number of Visible Satellites
  • GPS Fix data
  • Latitude
  • Longitude
  • Artificial Horizon
  • Heading (0-360)
  • Compass (N,E,S,W)
  • Pitch
  • Roll
  • Distance to home*
  • Direction to home*

*Based on spherical coords with geographic distortion corrected;

The hard work continues... but, the fun is already granted, of course!

Grab yours right now and happy flights! ;)

    Grats Sandro, this day finally came true. 

  • Distributor

    Great stuff Sandro, been looking forward to the release of this board!  now we have 2 OSD's to choose from!

    As many people know we will be stocking this MinimOSD along with many great DIYdrones products in our UK

    Great job, Sandro! I've been waititng for this .I believe this would also work with APM2?

  • 3D Robotics

    Congrats, Sandro! Just a note for everyone else: this is  a great example of a community-developed project. Two years ago, Sandro was just another community member. But he stepped up to contribute, first with great graphics work, then with dev team participation, and now as the co-designer of this OSD board.

    It's been inspiring to watch him grow and expand his skill set, and he's earned the respect and affection of the entire team with his enthusiasm, energy and amazing ability to wake up at crazy hours for the weekly dev calls!

  • Sweet, I'd like to see a demonstration setup of all the new hardware: APM 2 + minim OSD explained.I'll order one as soon as I get my APM 2 ;-)
  • Developer

    Nice!  Congrats Sandro!

  • We will need a FTDI cable to program this ?
