Re: STMF3 Discovery & Motors (RC car)
I agree about the likely motor type, although an older car motor might be brushed. Either way to get sufficient power into the motor will need a power driver and I think the best bet would be a standard rc car electronic speed controller (esc). They are available for brushed or brushless, and do the...

Re: Compiling duration
IMHO cmake is good for cross platform software and when you have lots of external dependencies. I'm not sure either really applies to our work with ChibiOs.
Generally I think we're OK with make for command line folks and maybe eclipse projects for those that want an IDE.

Re: Compiling duration
You always need a few seconds during the compile for a few sips of your favourite beverage. If its too quick I'd dehydrate

Re: ChibiStudio - Problem when cleaning project
It's not a perception, a process will have a "lock" on a file or directory. There is a utility called Unlocker that can list and "break" the locks. If you can find out what process has the lock you may be able to prevent it doing so in the future.

Re: Compiling duration
FYI timings on an i7, I primed the caches with a 'make' before these tests: $ time make make: Nothing to be done for `all'. real 3m23.188s user 0m45.067s sys 2m36.545s $ time make -r make: Nothing to be done for `all'. real 0m0.821s user 0m0.310s sys 0m0.420s $ time make -j make: Nothing to be done ...

Re: Compiling duration
On my machine using msys make for a win32 build takes an age. Passing the '-r' flag speeds it up immensely. The flag tells make to not bother with some built-in rules, I'm not sure if this affects the build in an adverse manner, but it works for me.

Re: [Announcement] ChibiOS Twitter
Personal opinion: Why? More communication channels doesn't mean better or even more communication . IMHO it just leads to a dilution of the message. Where are newcomers to go for help, the website, the wiki, or the forums, or the separate gfx website or now twitter?

Re: Floating point issue on Raspberry PI
Are you sure the object file for chprintf got recompiled? Did you "make clean"? I tripped over that when I was trying to get fp output last week.
