[sdiy] Audio hardware platforms?

[nvawter at media.mit.edu]

Hi, Martin!

Ah yes, I supported that/your kickstarter campaign for The Owl!   I  
think it's going to be great.  Like I repeat to everyone I meet, the  
stm32f4 is definitely a significant step forward for embedded digital  
music instruments due to its hardware floating-point unit.

I've been hoping that my project, MOBB, can share plenty of software  
with the Owl.  I truly believe that we're about to see a growth in  
digital musical instruments which have their roots in pre-sedentary  
musical instrument design, rather than being incidental "applications"  
of personal computers.

Thanks for showing what your hardware looks like.  My HW is slightly  
different.  It is more minimalist, with fewer peripherals built into it.

What is your software development environment like?  Which compiler  
and programmer?   I'm using GCC and Keil uVision.  So far, I can use  
external USB flashing over DFU and Single Wire Debug (SWD) with an  
STM32 cortex 3 or cortex 4 discovery board, but I would love to make  
this even easier for people.

Which libraries are you using?  So far I am using libopencm3.   
Technically, it is the same as ST's libraries, but it's a  
philosophical choice :)  And I know you're using JUCE as well...

Did you know that two people have worked a bit toward porting the  
Wirish library from the Cortex M3 to the Cortex M4?   
(https://github.com/gbulmer/openstm32sw) This would be very useful for  
our users.  I hope to look into this project and extend it.
