The crummy image we put up of the native shows a whole lot of pins going on: http://www.leaflabs.com/wp-content/uploads/2010/02/maple_native_proto.png If I recall there's something like 64 header pins plus the 48pin FSMC headers which could be used as GPIO if you don't want RAM... there aren't that many actual pins run out because some are ground/power, but there are definitely a whole bunch! Our base library (libmaple) is the foundation for the IDE and can also be used with gcc and other GNU tools... i'll finish that HOWTO soon but in the meanwhile you can see the README on the github page (http://github.com/leaflabs/libmaple). We're going to support libmaple on the maple native and any other stm32 boards we make (mini?); it should actually be pretty easy to port to other stm cortex-m3 projects as well. Hi Bruce!

Good to see some folks with a bit more electronic engineering experience to build such boards :) I'm more of the software. Although i must say that a basic Arduino can do a lot more than most ppl. think/experience... mainly due to bad coding styles :-/ What i wonder though, is `Maple 2'/ `Maple Native' going to have headers for the extra outputs too? The proto board doesn't show them yet. (pin 21-39). Will the libraries/toolkit be available as a gcc target? or only as an IDE? I'd rather prefer the 1st ! Keep up the good work!

What i wonder though, is `Maple 2′/ `Maple Native’ going to have headers for the extra outputs too? The proto board doesn’t show them yet. (pin 21-39).

Will the libraries/toolkit be available as a gcc target? or only as an IDE? I’d rather prefer the 1st !

Keep up the good work!

We are sorry to have slipped on casual deadlines but many of us have separate full time jobs or are full time students which makes logistics and forward planning difficult. The academic summer should free up a lot more hours in a week but we're doing our best to push out releases and new hardware before then.

sorry guys… but it’s painful and frustrating to see such a cool and promising project kill itself.

you should definitely try to be more communicative and transparent with us

sincerely your eager customers and maple fans.

The AVR Arduinos certainly do have a lot of power that can be tickled out with careful coding! Perhaps some of that power will be released in the uno punto zero release with some macros or fiddling about with the hardware libraries; we imagine that our libraries will be somewhat unoptimized as well, at least initially. A lot of what we're trying to offer with the Maple is access to advanced functionality (multimedia, communications, data processing) and multi-tasking without spending hours twiddling and debugging C and Assembly. The next batch of Maples will have headers on pins 21-39 and also a table silkscreened on the bottom showing the functionality of each pin. Maple Native is going to have... a lot... of headers... something like 112. That's a lot of kicad routing! The libmaple library is released/developed separately from the IDE; the workflow we use for development is to edit a main.cpp file that looks a lot like an arduino sketch and compile/flash that using command line tools, then use gdb over a jtag interface to do debugging. It's "pretty simple" once you get your development set up, but that's always more of a headache than you expect it to be, which is the whole point of the IDE. You can take a peak at libmaple on our github page; we've been meaning to write up a blog post about it: http://github.com/leaflabs/libmaple Thanks for posting! Hi Reinoud!
