CCS/RF430FRL152H: property issue

CCS/MSP-EXP430G2ET: print ADC value by using CCS (TRF7970ABP+MSP-EXP430G2ET -> RF430FRL152H)

Part Number: MSP-EXP430G2ET
Other Parts Discussed in Thread: MSP430G2553

Tool/software: Code Composer Studio

I want to connect MSP-EXP430G2ET and TRF7970ABP as a reader and read the ADC0 value of RF430FRL152H-Patch.
Because E2E community recommended a method called UART, I want to use it. Which of these codes do I need to read?

I downloaded anything, then imported.
And I ran it like this picture, and while it was being debugged, there was no output.
Is this normal?
I want the printed value. What should I do?

What function must be entered to output the ADC0 value of RF430FRL152H?!

And I'd like to print out the results of the ADC0 in the function(ex. multiply, add, and so on) that I made.
Is that possible?

    Hello,

    Yes UART is a communication protocol that you can use to send data to and from a sender and a receiver. In your case, you'd be interfacing an MSP430G2553 Launchpad to the PC using the back-channel UART circuit provided on the Launchpad. Please refer to the Launchpad's User's Guide for more information regarding the back-channel UART circuit.

    According to the user's guide, the back-channel UART is connected to USCI_A0 so you can use any UART example in the TI Resource Explorer  which utilizes the USCI_A0 peripheral. An example that would be good to start with is the msp430g2xx3_usci_uart_standard_transceiver.c example. With this example you can select the baud rate that you'd like and then use a terminal on the PC such as TeraTerm or PuTTY to connect to the UART COM port and begin sending characters to the PC.

    Once you have a handle on that, you can look at other UART examples which show how to initiate a UART transmission; which you can then modify and port over to your project in order to send the ADC data over UART to the PC.

    Best regards,

    Matt
