Well i'm not a pro on micropython (i just got my board a few days ago), but i do know something about python's speed. Just like any other language (even c++) the more you do, the more cpu it takes. Recursion is really slower because it needs to save the information about the current function while i...

thanks a lot Pete. I'm very glad to be able to bring something to the community. Like i said i'm studying fft by myself (my first project will be a spectrum analyzer) and i don't understand how it works. And just to clarify is not actually my code, i only ported this http://paulbourke.net/miscellane...

I think one of the most interesting contribution of micropython is the language itself. The board is awesome (i really love it), but the language is incredible. IMHO it has a lot of potential, to fill a gap in CPython implementation i've seen for some time.
I would love to try to make an os with it.

Yup pebkac in line 9. I fixed it and now it looks more like it. (i updated the original post) (btw notice that the other function modifies the list in place (on purpose)) >>> ll = [math.sin((float(n)/1024)*2*math.pi) for n in range(0, 1024)] >>> b = ll[:] >>> ffft(b) >>> [abs(x) for x in b[0:5]] [5....

Thanks Pete, honestly i dont fully understand the FFT yet. Must be a typo in the code, i did it on a hurried trip. I'll check it later while i study fft further.
it gave the same results for a list of range(4) but i guess it was meaningless.

That would be awesome! I tried making a game engine programable with python (much like panda3d) and i've managed to port it to unix, windows and blackberry 10 , but that's because i already knew how to compile python for those platforms.. but its really messy and complicated.. im actually making a g...

Really interesnting, i always wanted to make an OS in python.
I think uPy implementations is actually better suitable for that task as it can handle interrupts and custom asm.

Awesome thanks!

Threading in python is fairly easy, if you do a correct design it is not that bad. also using the queue class can solve most of your problems. however afaik CPython has only one concurrent thread*1 so it-s not that usefull unless you're doing some kind of IO ops (like you). maybe in upy you will nee...
