1 Introduction
The SLN-TLHMI-IOT development kit implements NXP’s EdgeReady turnkey solution
for smart Human Machine Interface (HMI) projects. A high-performance member of the
i.MX RT1170 microcontroller (MCU) family enables this solution. It runs on a Real-Time
Operating System (RTOS) under dual-core architecture. One is Arm Cortex-M7 at 1
GHz clock rates and the other is Cortex-M4 at 400 MHz, with 2 MB on-chip SRAM. The
smart HMI solution provides OEMs with a fully integrated, self-contained, software, and
hardware turnkey solution. It includes cross-platform framework, pre-integrated machine
learning vision, voice algorithm, a 2D graphics accelerator supported by Light and
Versatile Graphics Library (LVGL). The SLN-TLHMI-IOT also includes required drivers for
all necessary peripherals, including memories, cameras, mics, speaker, display, and Wi-
Fi + Bluetooth Low Energy combo chipset. A runtime license to this software solution is
bundled with the i.MX RT117H-numbered devices in the i.MX RT1170 family. The solution
enables developers to implement multi-modal smart interactions with Machine Learning
(ML) vision (face and gesture recognition), far-field voice control, and 2D graphical user
interface on their products. This functionality can be enabled by using only a single
high-performance NXP crossover MCU, simplifying the overall system design. NXP’s
cross-platform dual-core framework architecture empowers designers with the flexibility
to customize their products, making i.MX RT117H a versatile fit for numerous smart
HMI applications. These applications include but are not limited to both consumer and
industrial applications.
