Win? Fail?
On the todo list for future releases (in no particular order):
- I2C
 - External interrupts
 - Last bit of missing "arduino language" support
 - More and better documentation and examples
 - Ported Libraries (LiquidCrystal and Ethernet are mostly functional)
 - VGA library
 - Support for Maple Native, Maple Mini, and other STM32 boards
 - Your request here?
 
Looks like we've got at least one more little release in the coming months before a full blown 0.1.0.
