I had a question in my mind

It's impossible to tell, since encrypted data is just that, something that is not possible to interpret without the key, and the algorithm. If it was easy there would be no point in using it.

My teacher told me, that if we work for someone or some company, to develop their application. The application is to be handed over only, not the source code.

Is it true, that if someone hires me for a one-time software development, that I should only (at the end of the project) hand over the application (in an executable form) and not the source code for the project?

I take it your teacher has absolutely NO experience in the real world. The answer to this is that it depends entirely on your contract with the client. If your contract states you hand over code, then you hand over code - in fact, if you're a contractor then, chances are, that's what you're handing over.

Oh, so as, I mean these freelancer dudes, when they work for a project. They hand over the actual source code to the employer itself.

Yes, but as said, depends on the contract, also whenever you're working for a company as an employee (not contractor) whatever you create is property of the company.

Things are more complicated than what your teacher is telling you, my recommendation to you, "read the contract before you sign it"

I agree with Gonzoox, the first thing is to read the contract you've signed with the company that hired you...

OF need DOS / CMD reminder

13-Feb-15 6:20

OK I am stuck again and getting nowhere asking this on Arduino site.

To my best knowledge Arduino application is build using gcc compiler.
I know that gcc compiler is passed ton of parameters know how to find out their function / description.

I understand such parameters can be put into a batch file and Arduino folks apparently use plain x.txt file to do just that.

I am LITTLE familiar with .bat files syntax , but have not have any need to use bat files ages.

Now what I DO NOT KNOW how is this batch / platform.txt file is organized, its syntax etc.

<b>Could I get some pointers where to start looking for basic information about usage of txt files in passing parameters to compilers?

</b>

I am enclosing the entire platform.txt file in case it would be easier just to annotate it to show me what I am looking at or where to find what particular line is suppose to accomplish.

PS I am basically trying to figure out how is this platform.txt accomplishing the last task
- SAM3 Uploader tools, but I want to learn more about the txt batch files usage.
I have full access to BOSSAC source on github.

I really appreciate any help.
Thanks
Vaclav

Re: OF need DOS / CMD reminder

11-Feb-15 6:56

I have forgotten how to do "Run" / cmd in Widows XP.
For whatever reason I could not get the required application window to stay up.
So I looked up cmd options and now it stays up( even just "cmd") but won't run the application.
I understand that cmd may work differently in different OS, but I think I am missing some spaces or whatever to make it work.

cmd \k E:\Arduino_All\Arduino_160\arduino-nightly\hardware\tools\listComPorts.exe
the above just runs cmd

and same here
cmd \k "E:\Arduino_All\Arduino_160\arduino-nightly\hardware\tools\listComPorts.exe"

I don't get any errors, just plain cmd reply - Windows version. The app file exists.

Any help would be appreciated, in the meantime I'll try different combinations of " and spaces.

Cheers Vaclav

Try using a forward-slash for the /K argument:

cmd /k "E:\Arduino_All\Arduino_160\arduino-nightly\hardware\tools\listComPorts.exe"

How is this possible? Application cannot connect to detected COM port.

SOLVED ? Re: How is this possible? Application cannot connect to detected COM port.

10-Feb-15 8:59

I am trying to use two SAM3X8E processor bootloaders - SAM-BA and its cousin BOSSA.
Both will run and let me know that comm port COM4 exists.
But neither one of them will connect to it.

I am using same comm port to program Arduino Due, no problems.

I am suspecting wrong driver for bootloader apps, but how is is possible to correctly detect the port but be unable to use / connect to it?
Just asking.

Getting / building executable from github source

10-Feb-15 11:28

That was so easy - there is a "standard" Windows listComPorts and it is pretty given that anybody smart would not reinvent the wheel and use it to fill combo box.
So just because listComPorts found the port it does not mean that the application using it can connect to it.

Re: Getting / building executable from github source

9-Feb-15 15:57

I have never done this , so I am totally lost.
I just need some guidance, explanation of steps / concept from source files to x.exe.

( I am not sure for what to google )

I am guessing I need to somehow use "make".
I got all source files and have used dsp dsw in past, but I am not sure how to get there.
I managed to "build "makefile.dsw" but that where I am stuck.
I obviously need x.exe. So how do I get there from makefile.dsw?
Thanks

The process will vary from one repository to the next. If the repository doesn't have instructions for compiling the code, and it's not obvious, then you'll have to ask the owner.

Re: Getting / building executable from github source

10-Feb-15 5:21

Most packages will come with configuration/build instructions included, so you should read those in the first instance. If all that is provided is a bunch of source files with no instructions and no control files, then you will have to deduce it from the source, and destination systems. If it's destined for Windows then you can import the files into a Visual Studio project, which will do most of the work for you. If it's destined for Unix then you will need to create a make file, or run manual compile and link processes. Without more information it's difficult to suggest what is best.

Re: Getting / building executable from github source

10-Feb-15 8:51

After unzipping the whole github ( I really do no know what to call it) I ended up wiht several directories , inclunding "install", src and makefile file.
I guess I'll just import the source , as suggested, and build / compile it and watch for smoke.
Thanks

RESOLVED Re: Getting / building executable from github source

10-Feb-15 9:32

That seems like a very bad idea. If you cannot understand the structure of the package or how it should be built you are just likely to end up with a total mess. And if it includes an install and makefile, then chances are that you will definitely need to run make to build it. I would suggest you go back to where you got it from and find out exactly what it is you are trying to build.

Problem installing VS 2013

10-Feb-15 11:39

I am actually finding ways to resolve my issue without rebuilding the BOSSAC application.
But knowing how to get stuff from github will be handy.
I was actually curious - some coders add "readme" to help to navigate thru the repository.
This one is pretty cryptic IMHO.
It always makes me wonder why people publish code for public benefit ( I assume , why else it is publicly accessible ) and are so stingy with comments and "briefs" how it suppose to function.
But some do not forget to add " if you modify it , quote the source" stuff.
O well.
Thanks

Hello.
I have a problem installing VS 2013 express. The problem is that the installation does not take place. It shows me just a small black rectangle on the screen and it stays like that.

I have Win 7, SP1, all updates installed. What is the problem? Does anybody know, please?
