1. Introduction

1.1 The Design

This is a ref-design for Smart Watch Based On GR5526 BLE SoC, Supported 2.5D Embedded GPU and Lvgl_8.31 GUI Framework. Customers can get higher fps and enhanced performance for smart watch through the Chip's ability.

1.2 GR5526

The Goodix GR5526 family is a single-mode, low-power Bluetooth 5.3 System-on-Chip (SoC).

It can be configured as a Broadcaster, an Observer, a Central, a Peripheral, and supports the combination of all the above roles, making it an ideal choice for Internet of Things (IoT), LE Audio, and smart wearable devices. Based on ARM® Cortex®-M4F CPU core, the GR5526 series integrates Bluetooth 5.3 Protocol Stack, a 2.4 GHz RF transceiver, on-chip 1 MBytes programmable Flash memory, 512KBytes RAM, and multiple peripherals. GR5526 delivers a feature-rich display and graphics solution by providing the option of graphics acceleration (GPU + Display Controller) and system-in-package (SiP) 8 MBytes pseudostatic RAM (PSRAM) to accommodate display while still leaving plenty of resource for wearable schemes.

2. Smart Watch

2.1 Ref Project

The Ref Project is located at projects/peripheral/graphics/gr5526_smart_watch, It's compiled with Keil µVision5 in default. it also can be compiled by gcc and IAR.

2.2 Set UP the Development Environment

To Set up the development environment, the following software is required:

  • Keil µVision5: Integrated Development Environment (IDE) used by the Ref-Design project
  • Device Family Pack (DFP) that supports ARM Cortex-M4 FPU Chip
  • J-Link: programming and debugging tool
  • Serial port assistant tool: log printout
  • GR5526 family chip programming algorithm file for Keil: you can find the .flm file in build/keil

2.3 Hardware Related

  • This Ref-Design is based on the GR5526 Starter Kit Board. you can find introduction to SK board here GR5526_SK
