Shown here is the hardware needed for the demo: On the top left is the TRF7970ATB module, which plugs into the EM headers on the MSP430F5529 experimenter’s board. The blue jumper needs to be connected between P2.0 and P4.0 on this board to use the interruptible GPIO feature on P2.0. Make sure the power switch on the left side of the board is in the ‘LDO’ position. When the hardware has the correct firmware downloaded and is connected via USB, the heartbeat LED will be flashing.
