3.3 Hardware Setup for Single Device

The LP5890EVM can be powered either by the MSP430F5529 LaunchPad with the USB power (when the current consumption is low) or an external power supply (the LP5890EVM and the MSP430F5529 LaunchPad are powered separately). Single LP5890EVM can be quickly set up and tested by following these steps:

  1. USB Power supply from the MSP430F5529 LaunchPad
    1. Download the code to the MSP430F5529 LaunchPad with TI Code Composer Studio software.
    2. Put the J6 jumper on "MCU5V" and the middle, and set the switch S1 towards "SOUTHOST" , which are marked with red boxes in Figure 3-2.
    3. Connect BoosterPack connectors (J1, J2) on the LP5890EVM with the MSP430F5529 LaunchPad, the connection method is shown in Figure 3-2.
    4. Power the MSP430F5529 LaunchPad through the USB cable.
  2. External Power supply
    1. Download the code to the MSP430F5529 LaunchPad with TI Code Composer Studio software.
    2. Put the J5 jumper on "TP1 5V" and "EX 5V". Then put the J6 jumper on "EX5V" and the middle. Set the switch S1 towards "SOUTHOST".
    3. Connect BoosterPack connectors (J1, J2) on the LP5890EVM with the MSP430F5529 LaunchPad, the connection method is shown in Figure 3-2.
    4. Power the MSP430F5529 LaunchPad through the USB cable.
    5. Connect TP1 and TP2 to 5V/GND power source.
    6. Power on 5V/GND power supply.
