2 Using the TRF7970A EVM With PC GUI
2.1 USB Driver
The TRF7970A EVM has SiLabs CP2102 USB to UART Bridge IC onboard. The USB driver needs to be
loaded onto the PC being used prior to attempting to start the TRF7970A EVM GUI.

2.2 TRF7970A EVM GUI Startup
The TRF7970A EVM GUI has a COM port auto detect function which is limited to COM ports 1 through
12. This being the case, the user is advised that after plugging in TRF7970A EVM but before starting the
GUI, they check the COM port it enumerated on via Windows Control Panel, System, Hardware Tab,
Device Manager, Ports, Port Properties, Port Settings and ensure it is within this range and also that the
COM port settings are for 115200 bps, 8 data bits, no parity, and 1 stop bit (115200 8N1).
The TRF7970A EVM GUI should be downloaded from http://ti.com, unzipped into dedicated folder, and
then executable can be launched. Figure 2 shows the first screen the user will see when executable
launches and automatically connects to the TRF7970A EVM.
The user can scroll down in the data log window with the slider bar on the right side to see that the GUI
has connected to the TRF7970A EVM.
Figure 2. TRF7970A EVM GUI Connected
Figure 2 shows TRF7970A EVM connected to COM3 (as example). The EVM and the GUI are now ready
to be used together to demonstrate the RFID reader/writer and NFC Forum operations.
