1. Abstract

This document describes how to configure a watch graphics user interface combining the DA1470x features with the use of LVGL graphics library. The LVGL open-source lightweight embedded graphics library can be used in any application from battery-powered single chip products with basic graphic needs, to high-end embedded systems that demand ultra-high performance, and sophisticated animations.

2. DA1470x Multi-Сore Wireless SoC Family

The DA1470x is a family of multi-core wireless microcontrollers, combining the latest Arm Cortex® M33™ application processor with floating-point unit, advanced power management functionality, a Display Controller and a Graphic Processing Unit (GPU) for advanced graphics processing, a cryptographic security engine, analog and digital peripherals, a dedicated sensor node controller, and a software configurable protocol engine with a radio that is compliant to the Bluetooth® 5.2 low energy standard. The DA1470x Bluetooth LE SmartBond® System-on Chip (SoC) is ideal for developing wearable applications, usually refer to devices such as smart watches and wristbands.
