Determining Board Selection

[OzGrant 22]

G'day,

At the moment I change a #define that allows me to use different Libs depending on the board used.

Is there a #define statement that allows this to happen automatically at compile time?

This will allow me to use the same sketch regardless if its for a Tiva  or another launch pad.

Hi,

 

you can use the for sure the uC name:

#if defined(__TM4C1294NCPDT__) /*tivac LM4C1294 writes 4 locations at once;*/ 

In older Arduino IDE's I've used the board name as well, but not sure how the newer IDEs work:

 #if defined(ARDUINO_AVR_UNO) || defined(ARDUINO_AVR_NANO)

Regards,

Liviu

 

LE Because of the "command line defines" (-D compiling option), I think in the last Energia (1.6.10E18) you can use "ENERGIA_board-name", with the "board-name" found in the boards.txt file. For my TivaC TM41294XL, the boards.txt shows:

EK-TM4C1294XL.build.board=EK-TM4C1294XL

and the compile option is

-DENERGIA_EK-TM4C1294XL

In the latest version this has probably changed:

EK_TM4C1294XL

Hi Rick,

Thanks for the correction, it seems I have an older version (1.0.2) for the tivac package.

But the exactly name is not so important, it was just an example. Idea remains - one can use the board name from the boards.txt file in #ifdef tests.

 

Best regards,

Liviu
