By default, the RF path is routed to J3 (Murata RF Switch). To use J2 (uFL) for RF measurements, swap the
position of the 0-Ω resistor to disconnect the path to the onboard antenna, and enable the path to the uFL
connector.
5.1.1 Using the UART Interface
The emulation board enumerates the UART ports on the PC, as shown in
. Keep a record of the third
port number, because it is needed later for connection.
5.1.2 Using the SPI Interface
The SPI does not require users to choose a specific COM port. Simply select the CC31xx SPI option in the tool
to start the connection. However, with SPI connection, only one CC31xx can be connected to a PC at a time.
This is because Radio Tool cannot determine which CC31xx device to connect to if multiple CC31xx devices are
present. For large volume testing, TI recommends using the CC31xx UART.
5.2 CC32xx-LAUNCHXL
Connect the RF connector to a WLAN tester/RF equipment for measurements, and the USB connector on the
CC32xx LaunchPad™ to the PC. Ensure the RF connection to the instrument is made before powering on the
board, so that the correct load impedance is provided during power on.
By default, the RF path is routed to J11 (Murata RF Switch). If users want to use J10 (uFL) for RF
measurements, swap the position of the 0-Ω resistor to disconnect the path to the onboard antenna, and enable
the path to the uFL connector.
The LaunchPad™ enumerates COM ports in the Device Manager on the PC, as shown in
. Keep a
record of the Application/User UART port number, because it is needed later for the connection.
While using TI's XDS LaunchPad™, the RadioTool GUI should automatically detect the correct UART number
and set it on the GUI on the "COM Port" combo box.
