It looks like you are using either CCS or IAR, this code is not compatible with either one you may have to enable the interrupt another way (gie bit), and you will have to change how the interrupt is called (#pragma) please let me know how you get it to work and i will update my post to add your changes What compiler are you using?

I also tested on my build the g2211, and it worked with out a problem. Just to be safe i used the same files you did to do a test compile, including rake and make both compiled with out error. My guess is, something happened during the build....... or something is not linking right the only thing i can think of doing is uninstalling and reinstalling msp gcc but if things are still not working, i would try the mspgcc mailing list, and ask them on whats going on.

It looks like every time I write something between ” it dissapears, so if you see in my previous two comments #include and no header file, it’s because it was between these characters and dunno why it has been deleted O_oU

Sorry for these three comments.

I have installed the TI headers, they are under "/usr/local/mspgcc/msp430/include". In the source file, it's included "msp430.h". AFAIK, "msp430.h" should include the correct .h file ("msp430g2211.h" in this case) using the -mmcpu argument passed to gcc.

I got the examples to compile, replacing '#include ' with '#include ', so I supposed the mmcpu argument doesn't define the chip properly. Then I tested passing "-D__MSP430G2211__" to gcc, but it didn't work! It looks like even though I manually define the chip, "msp430.h" isn't able to see the definition ("msp430g2211.h" doesn't get included). Then I tried "#define __MSP430G2211__" just before #include and also no luck, it's like if this symbol never gets defined... I can live writting the include for the exact chip, instead of the generic one, but I would prefer to use the generic one if possible (for code reusability). Any suggestions on how to get it?

I have installed the TI headers, they are under “/usr/local/mspgcc/msp430/include”. In the source file, it’s included “msp430.h”. AFAIK, “msp430.h” should include the correct .h file (“msp430g2211.h” in this case) using the -mmcpu argument passed to gcc.

Now the funny stuff. I got the examples to compile, replacing ‘#include ‘ with ‘#include ‘, so I supposed the mmcpu argument doesn’t define the chip properly. Then I tested passing “-D__MSP430G2211__” to gcc, but it didn’t work! It looks like even though I manually define the chip, “msp430.h” isn’t able to see the definition (“msp430g2211.h” doesn’t get included).

In the first invocation, it looks like mspgcc doesn’t recognize msp430g2211 as a valid MCU. In the second invocation I try with mcu=msp430x2211 and it looks like compiler accepts it as a valid MCU, but can’t find register definitions :(

Any help should be great.
