Plug It In
Run your favorite terminal application to view the serial output from the MCU's UART (the recommended settings are: 115200 baud rate 8 data bits, no parity, 1 stop bit)
Open the device manager and look under the "Ports" group to define the port number of the FRDM-KEA's virtual COM port.
Follow these steps if you are unsure on how to use the terminal application to display information sent from your NXP development platform's virtual serial port.
Tera Term open source terminal emulation application:
- Download Tera Term from SourceForge and run the installer.
Select the serial option once you launch Tera Term.
A COM port will be automatically populated in the list if the FRDM-KEAZ128 board is plugged.
Configure the serial port settings (using the COM port number identified earlier) by going to Setup > Serial Port and change the settings to 115200 baud rate, 8 data bits, no parity and 1
Verify the open connection by checking the title bar in the Tera Term application:
PuTTY application terminal emulation application:
- Download PuTTY and run the installer.
- Launch PuTTY by either double-clicking on the *.exe file you downloaded or from the Start menu, depending on the type of download you selected.
- Configure the serial port settings by selecting the Serial radio button and enter the selected COM port number and change the settings to 115200 baud rate.
Click Open to open the serial connection.
Verify the open terminal window once enter the correct COM port and plug the FRDM-KEAZ128 board
NOTE: If the configuration is not correct, PuTTY will alert you.

2.2 Try Demos
Your FRDM-KEAZ128 KEA Freedom Evaluation Board comes pre-loaded with two demos:
DEMO 1 = LED blinking with interactivity using the onboard potentiometer.
The LED will blink faster and then switch colors when the potentiometer is turned.
DEMO 2 = LED brightness and dim
by pressing the user button, which uses the ADC and potentiometer
