The code is NOT finished. The hard work continues! ;)

OSD

Now we have a windows application to setup and configure the OSD.
Thanks to my friend Michael Oborne from Australia!

There is much more to improve and add, but it work pretty fine.
Current Panels Set includes:

• Home Distance
  
• Home Direction
  
• MAVLink HeartBeats
  
• Throttle
  
• Speed
  
• Altitude
  
• Battery voltage
  
• GPS lock
  
• Number of visible sats
  
• Latitude
  
• Longitude
  
• Pitch angle
  
• Row angle
  
• Heading angle
  
• Compass rule
  
• Flight Modes (ArduCopter and ArduPlane)

USB Host and Camera Control

The camera control part is already working with OSD.
However, deal with !MAVLink and USB Host at same time demands a lot of SRAM.

We have two options to complete the OSD+USB Host project:

• Customize a light OSD panel to fit better ATMega328p resources;
  
• Create a new board, based on ATMega2560 chip;

You can try the current code. Just do the checkout of the code from here.

Current:

• Mapping: commands from Canon PS (Power Shot cams) (OK);
  
• Coding: to adapt essential mapped PS commands to main PTP library; (OK)
• Coding: to wrap necessary camera resources into simple serial calls (OK);
  
• Mapping: necessary registers of the chip Max7456 to work as the OSD core (OK);
  
• Testing: sketch which read and write the basic Max7456 registers (OK);
  
• Design: create a basic charset to use on UAV projects (OK);
  
• Coding: to insert the charset into the Max7456 prototype (OK);
  
• Coding: to wrap all the Map7456 code into a useful library (OK);
  
• Coding: to implement OSD pannels for telemetry data on screen (OK);
  
• Coding: to merge "USB Host" and "OSD" code using the new SPI class; (OK);
  
• Coding and Hardware: to use the mini USB host shield (OK);
  
• Hardware: to develop an "all-in-one" small board (OK).
  
• Coding: to integrate ArduCam OSD with ArduPilot Mega via MAVLink; (OK)
• Coding: to create new OSD panels to fit ArduPilot Mega needs. (OK)

Future:

• Accept newest and smallest Canon PS without PTP from factory:
  
  • Use CHDK to open one parametrized PTP command to run internal LUA scripts;
    
• Accept cams with other brands (when possible to hack their firmware).
