1.8 Minimum Procedure for Turning on the LEDs

The minimum procedure for turning on the LEDs is as follows:
1. Verify jumper pin settings on the MSP-EXP432P401R LaunchPad development kit and the LP5569EVM board.
2. Connect the MSP-EXP432P401R LaunchPad to the LP5569EVM board.
3. If it is the first time to use the MSP432, install an XDS110 driver. See the MSP432P401R SimpleLink™
Microcontroller LaunchPad™ Development Kit (MSP‑EXP432P401R) User's Guide for more-detailed
information regarding the XDS110 driver.
4. Verify the XDS110 Class Application/User UART and XDS110 Class Auxiliary Data Port on the Microsoft®Windows®Device Manager.
5. Install and run the EVM software.
6. If the LaunchPad development kit is a new one or was used another purpose, the EVM software asks to update the firmware. Update the firmware through the top menu, File → Update Firmware. The EVM software restarts after updating the firmware.

2 EVM Software

EVM software is available for download from the Product Folder. The LP5569EVM is connected via USB to the computer and controlled with special EVM software (Windows 7 and 10 compatible). A
SimpleLink™ MSP432P401R LaunchPad™ Development Kit is used with the EVM to provide I2C
communication and external PWM, EN, and INT pin control with the LP5569 device via USB.

2.2 XDS110 Driver Installation

The EVM software uses XDS110, a back-channel UART-over-USB connection, so it should be installed properly.
Connect the PC and MSP-EXP432P401R LaunchPad development kit using a USB cable and open the Device Manager of Windows (Control Panel→Device Manager). Verify that XDS110 Class Application/User UART and XDS110 Class Auxiliary Data Port appear.
