Using Real-Time-Clock Library with ez430-RF2500 sensor demo

Hello everybody,

I'm trying to get the Temperature sensor demo programm  (Version 1.02) of the ez430-RF2500 toolkit running with the Real-Time-clock Library (slaa290). My goal is to attach the actual time of each measurement  at the end of the transmittted datastring and then read it a out at the COM Port.I  integrated the code of one of the examples in the demo_AP file but it doesn't seem to work with this interrupt BT_1sec_wake() I think. Also the example codes of the Real-time clock library  assume that the 32768 Hz Crystal is connected to the LFXT1. In the MCU_init module

 BCSCTL3 |= LFXT1S_2;                      // LFXT1 = VLO

says that the VLO is chosen and the LFXT1 is free  (i think the comment is wrong?).Is that correct? And as XTS = 0 in BCSCTL1 , this means that LFXT1 runs in low frequency mode, eg. 32768HZ.

I really appreciate any kind of help. I know this should be a really easy problem to solve but I'm pretty new to the microncontroller programming thing

 heres the code important stuff in bold.

Thanks a lot

Chris
