Qt does have quite a bit of overhead, but as long as you don't get too excessive, this board can handle it.

Plus, since this will be running plain linux, we as devs can use pretty much whatever GUI libraries we want, if any.

Hm, maybe it would be nice to have all developers develop in the same framework, so that all apps look kind of the same.

Even when using the same frameworks the apps would look wildly different. I don't see it as an issue if they don't look the same. The layout style (which is totally up to the developer) affects usability far more than the graphical appearance.

ok, sorry for no news.

I moved to a new house, and now i have the optical fiber. Our web designer is building the website.


we still need more coders.

I'm a chinese student.I'm working on a DIY calculator project,too.My plan is use the STM32F3 as the main processor.And the total cost is about $16(100 yuan).I think I can help with the translation.

Hi zweb, welcome to the forums.  You should introduce yourself <a href="http://www.omnimaga.org/index.php?board=10.0">Here</a>.

It's really difficult to program for an environment that's not available to you. Do you actually have your OS for the device available yet? We need that first or we won't even know what kind of libraries we'll have.

It's a generic enough ARM processor, correct? Why not set up a QEMU environment?

Nice, would be cool to be available even for chinese people.

ok, sorry for no news.

and dev on this platform is not necessary, you just need to do code able to be compiled by gcc.

Best is C++, cause the main project will be C++

other language could be usefull for no critic applications or addons.



Willrandship, you can buy the armadeus and a dev board. There is a hdmi output if i remember well. Linux distribution is available on their website.
I will buy one.

You can dev without a board. It need just to be able to be compiled by gcc.

I can write quite a bit of code that can compile on GCC without being cross-compatible to different architectures. The easiest ways involve using functions like sizeof(<type>) or inlined assembly.

I already have a Raspberry Pi. That should be much closer, provided I don't use the hardware acceleration.

Also, why buy the distribution? Is it that hard to make your own? (PS it's not)

i thought to use an open source distribution. there is some.

i found this board nice too : https://www.olimex.com/Products/OLinuXino/A13/A13-OLinuXino-MICRO/

and code can even be writed on a PC under windows, with QT installed, and just run MinGW for compile for PC. just run it on pc for debug and test.
The compilation will run same on linux.

I could maybe also help with that, I have some C++ knownledge. What graphics library will we use?

Hi, first time i read about this, and i have to say: i smell a good project in this

I don't know if you need anyone else but i'm not good at c++

My skills:
-html
-php
-c#
-ti-basic xD
-thinking capactity :D lol
- i'm in a very mathematical study so i know some things... And i'll learn a lot more...

Maybe you could try with your thinking capaacity to come up with awesome algorythms for e.g. deriving functions and give them to somebody else who can program them in c++ :D

1st: the thinking capacities fail a lot xD
2nd: i don't understand :o what's deriving?
3rd: idk what functions are avaiable to perform in the algorythmes
