WE need everyone that can help in the creation of the port so any one that has any knowledge with programing and can help please help
No need to start a new thread for this, I've merged it into the existing porting thread.

also I am willing to put in lots of time to help but I have no knowledge with programing so if anyone one knows were I can learn programing plz tell me and I will help out the best in my activities
Unfortunately, the level of programming knowledge you need to complete a digic 6 port is equivalent to several university courses. It's certainly possible to teach yourself (google will get you a bazillion results for "teach yourself programming" or similar), but you should expect an equivalent amount of effort. If you just want a supported camera, this would not be a good use of your time.

It will be a big challenge! I don'4 know anything about programming, and don't even want to learn, but I will help with testing.

I would help testing too if needed. My SX700 has firmware version 1.00e (ACID Info).

I don't think a firmware dump of 100e has been posted yet, so if you could get one that would be good to add to our collection. See http://chdk.wikia.com/wiki/Canon_Basic/Scripts/Dumper for dumping instructions.

That said, there doesn't seem to be anyone currently working on this camera, so it's unlikely to be supported in the near future.

Please excuse my slow reaction. Several things prevented me from dumping the firmware immediately, but here is my 1.00e dump.
I am not able to attach files more than 1.5MB, so I uploaded the 32MB bin file to sendspace. If I went wrong because I have missed the right place for firmware dumps please tell me.

Thanks. That's the right way to do it.  The dump looks OK, and confirms that 100e would need a different port from 100d.

I ordered a refurb sx700hs and it should get here today. I would like to start working on porting CHDK to this over the break. I'm new to CHDK porting. I do programming mainly high level in Fotrtran, C, Python, PERL etc. Not afraid of getting into Assembler but only have the rudimentary familiarity with it. Given that Digic 6's are starting to be ported to CHDK like SX60, SX710, SX280 etc, I am hopeful that we can get something going.


Thanks very much in advance to all the CHDK fans both novices and gurus alike.


Edit to add: Just got the camera FW is 1.00E

Edit: Jan 2nd, 2018 -- Now in the autobuild.


Original Post:

Thanks very much to the help of reyalp, I have made a port of CHDK on the sx700hs with firmware version 100E. This build is included as an attachment. This build works and has been tested on my camera. Obviously the testing has been limited to me. I've tested the following.

Tested:
Overrides -- Av, Tv
Bracketed shooting in continuous mode (Av, Tv)
DNG shooting
Scripted shooting (Lua scripts -- isobase, llibtst, hooktest)
Connected shooting -- ptpchdk
ptpchdk camtests

Dark subtraction
Long Exposure (2 mins)

Not implemented yet:
Video -- movie rec task

Issues: 
Ugly display updating (usual DIGIC 6 limitations)

I looked at code from other Digic 6 ports (sx280, sx60, sx710, g7x, g16) and adapted as needed for this camera.

Once again, I want to thank reyalp, without whose handholding, this port would not have been possible. 

Any testing feedback is highly appreciated.

I'd like to test it, but can not made SD card bootable. I have tried STICK, that find my test100e.zip file, but after that it crashed and did not do anything. I can not install CHDK with the firmware update mode either, because I did not find the firmware update option in the menu of the camera.
How to install CHDK for SX 700? thank you
