  • Page 2: Plug It In

    Welcome to the SLN-VIZNLC-IOT Getting Started Guide. This guide walks you through the process of getting up and running with your SLN-VIZNLC-IOT board. This guide takes you through the steps of unboxing your kit, running the out-of-box smart lock demo application, as well as downloading, modifying, and debugging the firmware source code for your kit.

  • Page 4: Register And Recognize A Face

    Let us get started with a demonstration of the out-of-box features of this application. To use the recognition feature of the SLN-VIZNLC-IOT, a face must be registered in the local face database of the kit. To begin registering a new face, press the Manual Registration button (SW4) on the kit.
  • Page 5 SLN-VIZNLC-IOT-GSG NXP Semiconductors SLN-VIZNLC-IOT Getting Started Guide Figure 6. Registering screen Figure 6 shows that while registration is taking place, the GUI displays: • A “Registering” message • Face alignment guidelines • A countdown timer bar The guidelines help you align your face correctly during registration, and the countdown timer bar indicates how much longer it takes until the registration process times out and fails.

    Successful” message. 2.5 Connect to serial CLI The Smart Lock software installed by default on the SLN-VIZNLC-IOT kit provides a convenient serial-based CLI. This CLI is used to retrieve useful runtime data and configure various application settings. Connecting to the serial-based CLI of the kit can be done using a serial terminal emulator program like PuTTY or Tera Term.

  • Page 11: Installing The Sdk

    It is available in custom downloads based on user selections of MCU, evaluation board, and optional software components. Before building the SLN-VIZNLC-IOT SDK example projects, the target SDKs (EVK-MIMXRT1060 and K32W061DK6) must be imported into MCUXpresso IDE. However, no need to import LPC845 as it is already preinstalled in the IDE.
