HI, 

Here is the sony-interface project: http://we.tl/vFHUyqil89. We stripped a camera to reduce the weight from the initial 220 gram to only 50 grams, and put the composite out signal through a wireless transmitter, which is turned on and off together with the camera.

In the Sony, all the buttons and menu's are on 2 small boards connected with FCC cables. So I made a new PCB with exactly those connectors on it, controlling all functions. I also put 3 real buttons on the PCB to be able to still use the camera by hand (on-off, function, select). The PCB can be controlled through 3V uart, PPM servo signal, SmartPPM (servo movements encode bits) or via I2C. 

Most buttons nowadays are analog multiplexed with resister pull-downs. You have 5 buttons on 1 wire. So I could control 20 buttons with only one 4-channel Digital Analog Converter. 

There are also "normal" buttons, e.g. on-off and shoot. 

I hope you can reuse parts of this project. It should flash in an arduino mini too, but then you probably want to remove the DAC code etc. However, the I2C and UART, and the command decoding which are directly compatible with paparazzi could probably remain.

Hello,

Thank you for all the replies.

Sergey, it seems that KroozSD is a very talented board. It has 10dof sensor
and a lot of ports. I want to buy one, but I dont know what will be the
price of it at the end of the bidding.

Also, please add the details of the board to wiki soon.

Christophe, could you please share your code of Sony DSC control?

Cheers,
Refik

The solution with I2C controlling another processor is already implemented
in paparazzi: digital_cam_i2c. We have atmega code (fits in an
arduinomini) to control all functions of a sony DSC that we can share is
interest exits.

Actually all the paparazzi autopilots with the same architecture have the
same source code and the code is tested a lot. Problems could possibly
begin, when trying to use some new features or peripherals, or if
operating the hardware out of the designed conditions (for example current
overload). So using the standard software configuration (ready airframes
examples with a little changes) is reliable enough to have a stable flight.
Regarding the camera control - the possible configuration depends on your
particular camera. I'm a big fan of a hardware unification, don't like
using lots of external adapters and so on. That was actually the main idea
of developing the Krooz and the latest KroozSD
http://paparazzi.enac.fr/wiki/KroozSD
autopilots. You will only need to extend your airframe configuration with
you custom camera control routine (there are some ready solutions among
the camera control modules).

You can purchase the KroozSD board by bidding your price here on Ebay:

Regarding the NEX5 control - the control actions, like making a picture or
video shot could be done using a ready servo channel controlled solutions
like this one

roducts_id=688&zenid=1cc5cdb006c5f73d62832cb3c68b3441
or just using one of the free controller pins and an infrared led with
this module

Guys! Let me introduce my new Paparazzi based autopilot board - the
KroozSD.
http://paparazzi.enac.fr/wiki/KroozSD

The KroozSD board is the latest generation of the Krooz board, equipped
with the microSD card slot, XBee connector, as well as improved power
supply circuitry, capable of handling the most of possible applications:
http://paparazzi.enac.fr/wiki/KroozSD#Features

You can bid on the first samples of the KroozSD board on my Ebay auction:
http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=151027975394

I hope you will love it, guys!

Always ready for your questions,
Sergey
