STM32F4DISCOVERY Support?

[sirri 28]

Is it possible to compile STM32F4Discovery using Energia?

[roadrunner84 466]

No, Energia can only build for msp430. The Arduino environment is identical, but builds for avr. As the core is gcc, it would be possible to make another one for stm32. Alternatively you can use arm-gcc and Eclipse.

The not-yet-released beta version of Arduino version 1.5 has better support for non-avr chips and a more flexible scheme for invoking arbitrary toolchains. Look at the how it deals with the ARM chip in programmer.txt

However, you would still have to supply an implementation of the library code. Not sure how useful the ATMEL SAM chip stuff would be. There is an older version of an STM32 Arduino implementation called Maple from Leaflabs. It is significant effort to support an Arduino style API for arbitrary chips.

 

The new tree for arduino 1.5 is here:

Personally I would just learn to use the ARM Eclipse plugin.
