4.3 MSP-EXP430FR5969 Details

The TPS23882B1 accepts the MSP-EXP430FR5969 evaluation module when the application requires management of the TPS23882B1 devices with an external controller.

  1. Install MSP-EXP430FR5969 onto BOOST-PSEMTHR8-097 and ensure that the USB2ANY ribbon cable is NOT installed into J2.
  2. Connect the PC to the LaunchPad as shown in Figure 2-3.
  3. The source code was developed for the MSP430 LaunchPad Development Kit (MSP-EXP430GFR5969) using the Code Composer Studio™ (CCS) version 7.2.0 development environment. The target MSP430 can be programmed within this environment.
  4. Once CCS is installed, use the basic set of instructions listed in Section 4.3.1 to import, build, and run the project. CCS version 7.2.0 is used in the following examples. Note that a terminal program such as HyperTerminal or Teraterm is required to view the output from the EVM when it is running.
