Setup of Demo System
In this case, disconnect the TRF7970AEVM and reconnect it, then restart at step 1. If this still does not
solve the problem, make sure that the TRF7970AEVM has the latest firmware downloaded from the
TRF7970AEVM tool folder.
9. In the "Setup Tab", select the "With Sensor Hub BoosterPack" and "RF430FRL152HEVM" options on
the Device Interface Selection.
10. Select the "Demo Mode" tab.
11. Click the "Start Sensor Hub Demo" button.
12. The GUI starts to plot the temperature and light intensity samples on the graphs.
(a) To plot these values, the PC GUI configures the RF430FRL152HEVM through the TRF7970AEVM
to take three different samples from the Sensor Hub BoosterPack. The RF430FRL152HEVM
already has the drivers loaded into the FRAM to enable the measurements to be made.
(b) When the samples are complete, the PC GUI reads the result from FRAM of the
RF430FRL152HEVM through the TRF7970AEVM and plots it on the graphs in the PC GUI.
13. To change the measurements, you can place your hand over the light sensor or heat the thermistor
(U5).
