[I2C not working MSP430g2553 launchpad]

Thanks.  I will follow up with the suggestions.  Very much appreciate your advice.

[I2C not working MSP430g2553 launchpad]

Forgive if this is a naive question.  I don't want to trample down a hw/sw path that does not work.

 

Can someone please tell me if indeed it is possible with Launchpad MSP430g2553 w/ Energia (then XCodeEmbedded+ on top of that) to write a .ino sketch that does I2C in the same way it works on an Arduino Uno w/o Energia? i.e.:

#include <Wire.h>

 

void setup() {

     Wire.begin();

     Wire.requestFrom(ADDRESS, 2);  //assume ADDRESS is defined

}

 

if so, it seems there are difficulties in getting this interface to work.  Is there a list of difficulties with suggestions on resolutions (say a FAQ) for this?

 

thank you.

[embedXCode + LaunchPad + realloc() = "...not declared in this scope"]

thanks very much.  I did try #include <cstdlib.h> with no success :-(.

[embedXCode + LaunchPad + realloc() = "...not declared in this scope"]

I am using embedXCode+ on a Launchpad MSP430

 

 

I am trying to use arduino-menusystem:  https://github.com/jonblack/arduino-menusystem. The MenuSystem.cpp uses realloc(). While this works fine if the board is Arduino Uno, I get a "not declared in this scope" when building for the Launchpad.

 

Is there a better dynamic memory allocation routine to use when writing for the Arduino IDE? OR advice on how to fix this? (thank you)
