MSP430FR2533: CapTIvate Design Center Communication Interface

Part Number: MSP430FR2533
Other Parts Discussed in Thread: CAPTIVATE-PGMR

Hello, 

I'm designing a device using MSP430FR2533 and some CapTIvate buttons. I would like to use CapTIvate Design Center to monitor and tune buttons behaviour. I have few questions regarding the connection between the target MSP and the PC where Design Center runs:

  1. Which UART shall be used to communicate between target MCU and Desing Center ? The Design Center GUI allows selecting just "UART" but no way to specify UCA0 or UCA1. I could not find any documentation about it in the device datasheet or CapTIvate docs.
  2. I suppose that an external USB-UART cable shall be used to phisically connect the PC running Design Center and the target board. Is it correct ? How I specify in Design Center the related COM port where the MSP uart pins are connected ?
  3. This is a general question: what is the intended usage of I2C Communication Interface selectable in Design Center GUI ? how I connect a PC using I2C ? Probably there is something I'm missing about this aspect.

Thanks and best regards

Fabio Mannino

  • Hello Fabio,

    Are you using the CAPTIVATE-PGMR board to communicate with your MSP430FR2533 target device? Please refer to the Design Center GUI -> CapTIvate Design Center Quick start -> Communicating with the target and MSP-CAPT-FR2633 Development Kit -> Using the HID Bridge sections of the CapTIvate Technology Guide as these address the majority of your questions. The CAPTIVATE-PGMR includes an on-board HID Bridge to communicate with the CapTIvate Design Center using whichever communication peripherals are connected. These peripherals (UCA0/1, UART/I2C) are determined by your CapTIvate CCS project initialization. A HID device is required to use the CapTIvate Design Center.

  • Hello Ryan,

    I'm just designing the target board, I used the MSP-CAPT-FR2633 development kit in the past during a demo; now I want to design my own board so I investigated which hardware connections I should add to my board in order to communicate with a pc running Design Center. I don't have the kit right now.

    Is the whole kit required to use Design Center with a custom board ? or at least the CAPTIVATE-PGMR board ?

    Thanks,

    Fabio

  • Hi Fabio,

    The whole kit is not required but the CAPTIVATE-PGMR board is necessary for the HID bridge functionality, a similar FET board could be designed but the firmware is not provided publicly.

  • Hi Ryan, 

    I read the documentation you pointed me, I have few more questions.

    • Suppose I decide to use UART to communicate with programmer board, I will route the RX,TX pins of my target UART (one of my choice) and will connect them to BRIDGE UART RXD/TXD pins of CAPTIVATE-PGMR communication connector. Are SYNC (pin 3) and BRIDGE IRQ (pin 4) also required ? if so, where should they be connected to the target MCU ?
    • I suppose that pushing the "generate source code" button on Design Center everything will work on target mcu side, but I still miss where to specify the UART I use in my target.
    • I was trying to start a new test project for MSP430FR2533 but my Code Composer Studio (Version: 6.1.1.00022 ) has no FR2533 entry in Target list of New CCS Project dialog box. Shall I update to a newer CCS ?

    Thanks and best regards,

    Fabio

  • Hi Fabio,

    The SYNC and IRQ pins are not required. The baud rate can be changed inside of the source code definitions after it is generated by the Design Center GUI. And yes, please update to CCS v6.2 or 7.1 for FR2533 support.

    Regards,
    Ryan
