trying to load default code back into launchpad

Hi Todd,

You should not include any other header files.

In the header file you included they are just defined slightly differently. The new definitions are as follow:

TIMER0_A0_VECTOR (instead of TIMERA0_VECTOR)
TIMER0_A1_VECTOR (instead of TIMERA1_VECTOR)

The definitions are the same, its just the name that changes. That is just one of those things to watch out for when migrating to a new uC, and you should be able to view the definitions from the header files directly just to verify any possible changes, they are stored in:

IAR - C:\Program Files\IAR Systems\Embedded Workbench 6.0\430\inc
CCS - C:\Program Files\Texas Instruments\ccsv4\msp430\include

Best Regards,
Matt J

Matthew is right about the name change.

The reason is that there are now several MSPs which have more than one TimerA. Hence the change from TIMERA0_VECTOR to TIMERx_A0_VECTOR.

I had preferred something like TIMERAx_VECTOR0/TIMERAx_VECTOR1, which is way more 'telling', but does not comply with the naming of all other vectors which end on '_VECTOR' only.

Matt,

i noticed exactly what you are describing, so i see two paths to follow from here:

1. i could leave the header file in that was there when i downloaded the project ( "msp430x20x2.h" ). when i do this i see the following errors

errors encountered during linking; "MSP-EXP430G2-Launchpad.out" not built        MSP-EXP430G2-Launchpad    line 0    1311856154194    7437

if i leave this header file in, how do i go about resolving these errors. it seems like i am still missing another header file or something.

2. i could try to replace the header file with the header file for my device (like i described above). in this case, i get the two errors i mentioned above. so i find the spot where those two errors are and rename the timer vectors used to the ones actually defined in the .h file for my device. as you said, the definitions are the same, its only the name that changes. so when i do this, the code now compiles and i can load code to my device. the device still does not work like it did when i pulled it out of the box however, leading me to believe that it was not just a name change in the .h file. below is a description of how the code behaves now:

LED9 (the center led) blinks at full bright, in tandem with LED7 (one of the ring leds) at half bright. LED1 blinks full bright along with the first two. LED2 blinks full bright out of sync with the other two. This is the 'pre application mode'. When i press button P1.3 the lights go out and then LED7 comes back on at half bright. from here i cant hit the center button to toggle the light, i cant use the scroll wheel and see the lights, i cant see the circle light display when i wave my hand after the board went to sleep, etc. any of the functionality that existed when i took the board out of the box is not there now.

perhaps i chose the wrong project? or i still have a .h file missing/wrong?

You should always use the header file that belongs to your MSP, as it not only defines the symbols, it also assigns them the physical addresses of the registers, whcih can be totally different across different MSPs (even if their meaning is the same).

If a symbol is not defined in the new header file, this may indicate one of three cases:
1) the associated register and therefore the intended functionality is not available on this MSP (and adding the definition won't add it to the chip :) )
2) the name has changed from some reason (which happened in your case) or
3) the new header file is buggy and someone has forgotten to add this symbol. which rarely happens. Aven more rare for often-used things like the timers.

any idea what will be the fix for a problem like that?

I am using the MSP430G2231 and I included the respected header file but still get those 8 erros regarding the TACCR0/1 TACTL0/1 TACTL and TAR etc..

i am using the MSP430 LP Rev 1.4 connected to Win7 and using CCS  5.2.1.00018.

I did update the firmware to 2.0, as it seemed to solve most of the reported issues. But still I cannot debug/build anything.

tried. with no great luck :-(

Could you please post the exact error messages? Which MSP do you use, which header file do you imclude?
