Hi,

I'm very pleased to see that p14p switched to a more liberal license (https://code.google.com/p/python-on-a-chip/source/detail?spec=svn171940533b22d18c9df77a1dd60126a3c0511d78&r=171940533b22d18c9df77a1dd60126a3c0511d78). I just want to say thank you for making this change, even if it means a little less income for you.

Perhaps the license on the Google Project front page should be updated as well?

I was doing this in quiet for a specific reason (good news) that I
plan to announce soon.

For now, let me clarify for everyone:
The default branch is now licensed under the MIT License.
The v10 branch is still licensed under the GPL 2.

The Teensy 3 is coming out.
http://www.kickstarter.com/projects/paulstoffregen/teensy-30-32-bit-arm-cortex-m4-usable-in-arduino-a

looks like its going to be quite successful. USD22 a piece
Specs on the page above.
128K flash, 16KRAM, 2K eeprom

It looks like it might be a good candidate for the hacker community.
Can anyone more knowledgeable indicate its suitability ?
Paul (author) has indicated he doesn't know anything about python -
would like to help but can't take the port on.

Cheers...

Regarding to memory specs it should be feasable, so if there's a C compiler for it should work :-)

The only drawback that the eeprom is too small to store pymite, it would be nice to have it there and store python apps on the flash in a similar way like Arduino bootloader does :-P

Sent from my Android cell phone, please forgive the lack of format on the text, and my fat thumbs :-P

There are many many Cortex M0, M3 and M4 boards coming out.
For example, here's a cheap M3 board: http://hackaday.com/2012/09/12/stm32-f3-discovery-dev-board-includes-some-extras/
and a cheap M0 board: http://www.newark.com/freedom

As all Cortex chips share the CMSIS library for peripheral access, I believe the differentiator will be the toolchain.
The GNU toolchain is free and available, but sometimes a bit tricky to use.
I like the mbed platform because of instant tool setup.
Here's another project that offers a Cortex chip and a web-based toolchain:
http://www.kickstarter.com/projects/kuy/galago-make-things-better/

The takeaway here is that the microcontroller industry is converging around ARM Cortex
and the right device for you will be the one with the right combination of memory, peripherals, pins and price.

Yes the Galago and teensy are very similar and both look worth supporting.
The Galago has fixed point only math but has an in-circuit debugger and
a toolchain that comes with it.
The Teensy 3 has an FPU unit included and a separate bootloader
mechanism. The toolchain is also explained.
