5.1 Setting Up the Hardware

To set up the hardware, do as follows:

  1. Fit the CC256XCQFN-EM on the EM BoosterPack Adapter (BOOST-CCEMADAPTER).
  2. Stack the BOOST-CCEMADAPTER onto the MSP432 LaunchPad (MSP-EXP432P401R).
    Note: The boards must be set to their default settings.

    For more information on the jumper positions and default settings for the BOOST-CCEMADAPTER, see the CC256XCQFNEM Quick Start Guide and the Dual-Mode Bluetooth CC2564C QFN EM User's Guide. For jumper positions and configurations for the MSP-EXP432P401R development kit, see the MSP432 LaunchPad Development Kit User's Guide.

    Ensure that the connectors of the LaunchPad and the BOOST-CCEMADAPTER are aligned.

  3. To use the CC3200AUDBOOST device for audio and voice applications (optional), do as follows:
    • Ensure that the directions of the PCM signals are properly set on the CC256XCQFN-EM to evaluate audio and voice sample applications. The directions of the PCM signals can be configured so that the PCM port on the CC2564C device is either PCM master or PCM slave, depending on the sample application. See Table 5-1 to ensure that the R18, R19, and R11 on the CC256XCQFN-EM are properly configured for complete evaluation of the audio and voice sample applications.
      Table 5-1 CC256XCQFN-EM PCM Direction for Audio and Voice Sample Applications

      Figure 5-1 shows the position of the R18, R19, and R11 resistors on the CC256XCQFN-EM board.

      For more details regarding the PCM role selection on the CC256XCQFN-EM board, refer to CC256xCQFN-EM User's Guide and Dual-Mode Bluetooth® CC2564CQFN-EM Evaluation Board.

    • Connect the CC3200AUDBOOST audio codec board to the BOOST-CCEMADAPTER and the MSP-EXP432P401R, as shown in Figure 5-2.
    Note:

    Because the BOOST-CCEMADAPTER and CC3200AUDBOOST BoosterPack pinouts conflict with each other, the CC3200AUDBOOST cannot be stacked on the MSP432 LaunchPad while the BOOST-CCEMADAPTER is being used. Minor prototyping and jumper wire connections are required to connect the CC3200AUDBOOST with the BOOST-CCEMADAPTER and the MSP-EXP432P401R.
