Feature Request: EMT Closure Available Features

[rei-vilo]

As issue energia/msp432-core#40 concerns all EMT-supported boards, maybe this repository is more suited.

Here's an example:

MSP432 EMT on Energia 18 fails, even for the blinky example.

MSP432 EMT on Energia 19 succeeds to compile the SwitriggerLibrary example.

Suggested solution

Add to the TI-RTOS closure a list of available and implemented elements, e.g.

#define EMT_HAS_SWI 
#define EMT_HAS_TASKS
#define EMT_HAS_EVENT
#define EMT_HAS_SEMAPHORE
#define EMT_HAS_MAILBOX
#define EMT_HAS_TIMER
#define EMT_HAS_CLOCK

Two options:

• Either use 1 and 0 to flag the implementation of an element...

#define EMT_HAS_SWI 1 // 1 = SWI implemented, 0 = SWI not implemented

...to be tested with #if (EMT_HAS_SWI == 1) ... #endif

• Or define the macro only if the implementation is done...

#define EMT_HAS_SWI // define = SWI implemented
// #define EMT_HAS_SWI // comment = SWI not implemented

...to be tested with #if defined(EMT_HAS_SWI) ... #endif
