help to use terminal window during serial communication (UART)

Other Parts Discussed in Thread: MSP430F5419A

I got MSP-FET430U5X100 which includes USB programmer and 100 pin target board. I'm using MSP430F5419A micro-controller and Code-composer studio v5.3. I'm learning serial communication via UART.  When i connect my target board through USB programmer it is connected in COM port no. 26 . i downloaded and debugged example code of UART into microcontroller.

When the program is in running in debug mode, i can't use the port COM 26 in the terminal window software(Teraterm) to connect to the target board because it's already used.

* How to view the characters sent through UART in terminal window?

* Do i have to connect UART pins to computer seperately? or it's already there in MSP-FET430U5X100 (connection is through USB cable to JTAG header)?

    Karthikeyan,

    Some versions of the firmware on the USB FET Programming tool use a virtual com port on the PC for communication.  Your development environment uses this com port to communicate with the FET tool to program the MSP430.

    If you want a debug UART out of the MSP430, you will need to configure on the USCI modules on the MSP430F5419A, then manually create a connection to a com port on your PC (or to the serial side of a USB to serial adapter).  Then you can send and receive serial data to the MSP430.

    Alternatively, you can use some of our other development tools (such as a Launchpad) that have a "backchannel UART" built into the emulation side.

    Thank you Mr.Mike. Is there any way i can simulate the output. IAR workbench has peripheral simulator. Can that help to simulate the code and check the output without using harware?
