Re: [Paparazzi-devel] atmega_i2c_cam_ctl ???

Vision_Results shows a histogram/bar_graph plot with 12 columns. 

It was used to visualize the results of onboard vision (horizon detection).

A serial console is perfect, but in the past the only problem was that NXP only had 2 serial ports. This is why almost all our "add-on-payload" used I2C instead.

Hello Christophe,
can you tell me what is the program "vision_result"?

All my canon sx200 are broken so i not have time/hardware to make new
tests using canon serial console.

BTW, have news about Uploading GPS info into photo-file using CHDK

canon serial console is the best way to send GPS data to CHDK.

Hi Chris,

I made this to control our Sony Cybershot. However, we are working to convert it for CHDK.

-There is already a ground station GUI to control all the buttons, which works with all 3 types of cam_control. [https://github.com/tudelft/paparazzi/tree/tudelft4.0/sw/ground_segment/tmtc/TUDelft]
-There is Sony-Firmware for ATMega (using DAC's to control all the 30+ buttons multiplexed on 4 analog lines)

Ongoing:

-Conversion of the firmware to Arduino (since that seem to be cheaper, and performance is not a real issue here)
-Adaptation to CHDK
-Uploading GPS info into photo-file using CHDK

-Christophe

Hi.
I was getting ready to write some code for making a atmega chip control a Canon 230HS
with CHDK when i saw this file in the modules directory.
In fact it is exactly what i wanted to do but it looks like someone beat me to it.
Anyone knows where to get the atmega firmware (in any form, code or hex) and the CHDK script?
Chris
