Hello !
I've made an automatic ambient music generator for 70's parties... Laughing
The ARM Cortex M4F 168 MHz STM32F4 microcontrollers are very capable devices for sound generation and treatment. There are several free tools to program it : I've used Coocox coIDE, Eclipse, launchpad.net ARM GNU tool chain, Yagarto tools, ...
If you're interested, you can watch demos here :

Complete code is here :

Enjoy and happy new year !

Very nice!

Thanks for including a pre-compiled hex file - made it very easy to try out since my build system isn't the same as yours.

Quick note: the file stm32F4xx_syscfg.h seems to be missing from your git.

Thank you for your feedback !
Well, it's fixed now. The file was not missing but badly spelled in another one ( case sensitivity problem which will appear on Linux and not on Windows).
I've also succeeded in building the projet under Linux now.

Yeah, I found & fixed the case-sensitivity issue not long after posting.

Cool stuff - keep on coding!

THX !

Hi Eric, I've just realised who you were...Master Of The Modules ! Hail the Master
I was very interested in your STM32F4+Codec board but I can't see how I'd be able to cleanly assemble the parts...
I wish you sold populated boards !!! Is there any chance... ?
Anyway I've read and studied a little your delay example a few months ago ! Bravo for your very informative site.

Cheers
Xavier

Sorry, no. I've tried building and selling stuff in the past. It worked out OK, but it got to be more work than fun. You really ought to try building stuff though - it's not nearly as hard as you might think. Just need a good soldering iron, some tweezers and maybe a lighted magnifying lens.

Glad you were able to benefit - that's why I put that stuff up.
