Re: Recommeded C++ dev environment ?

<clip> Now some "why comments" are still useful but those are very much in the minority.<clip> This is where your argument fails. The whole point of comments is 'why', not 'what'. Of course you can see what has been done by reading the code. That is not true for why it was done. For example, it is ...

Re: Recommeded C++ dev environment ?

And responding to the OP: I recently came across SciTE ( http://www.scintilla.org/SciTE.html ) which is a very nice looking editor, with some basic tools that should allow for building makefile-based projects. Problem is, there isn't an ARM build of it (yet). It looks like it should be lightweight e...

Re: Recommeded C++ dev environment ?

(Make)... terminology is IMO hard to grok. That is my point. If you already know how to do it, then Makefiles should be simple. Learning to do it from GNU manuals or other resources available online is the complete opposite of simple - at least it was hard for me. I hope I'm being clear. Clear, elo...

Re: Recommeded C++ dev environment ?

With commandline tools, since you've edited your program source file you already know it's name. Beyond that, all you need to know is the name of the compiler to run, and if you don't know that then you don't deserve to be in computing. This alleged "barrier" is orders of magnitude smaller than lea...

Re: Programming the ARM chip

It seems to me that all the OP needs is a bootloader that provides GDB stubs for remote debugging over RS232 or Ethernet. S/he can then write whatever code s/he likes and get it running on the ARM with no OS. Unless the OP wants to learn how to bring the ARM up, in that case maybe writing (or portin...

Indeed, which is why all Scout Groups (in the UK at least) have been required to admit girls since 2007 before that individual Scout Groups could decide whether to admit girls or not.

Good. The system I'm working on right now has all LEDs controlled via GPIO, its much better to have a PWR LED connected directly to the power supply so you can see if you have power just by looking.
