EVM430-FR6047: MSP-430FR6047

Part Number: EVM430-FR6047

Hi,

I am using EVM430-FR6047 and using Ultrasonic sensing Design centre application (USS) to interface the same.

I am able to connect the application with the EVM and able to measure the flow .

I checked in the code and found that the communication with the Application is currently through I2C . I want to change it to UART so I modified following line in

comm_config.h file

original line was :     #define COMM_SERIAL_INTERFACE (COMM_I2CSLAVE)

changed line is :      #define COMM_SERIAL_INTERFACE (COMM_UART)

With this change I have built the code and debugged with the EVM, but now the USS application is not getting connected to EVM . please note that the jumpers RXD , TXD are placed.

How the communication is established on UART?

Thanks in Advance

  • Hello Suhas,

    I remember this was possible with the early internal releases. I have not touched that for ages anymore. Changing the MSP430 side would not be enough; I believe you would need to touch the PC-side as well (Design center). I will check on that and let you know. In my applications I am using the UART-link to have a back door access independent of the visualization on Design Center via I2C.  Was there a particular reason why you wanted to change to UART (free up the I2C pins ???).

  • Hi Johann,

    Thanks for quick reply.

    Yes I want the I2C lines to be used for other purpose and want to send data on serial port which I can able to also see on terminal utility independent of Design Application.

    Request to send modified Design centre application.

    Thanks and Regards,

    Suhas

  • Hi Suhas,

    I strongly recommend to keep that specific port for design center communication. Even if you are able to redirect the lint via UART your setup is not mainstream anymore. You always have to modify.  Am still checking if a re-direction is possible on the PC-side. ..but am not in office for a couple of days.
