430BOOST-SENSE1

Hi, everyone!

I want to use this amazing booster pack for msp430g2452, so I`ve downloaded the user experience example and tried to change it a little bit.

But i am experiencing some interesting issue. When I hold the middle button, the program can`t recognize that.

Please find the program below. It would be great, if you can tell me, what I am doing wrong.
