1 Introduction
A31T21xRLN Shield Board Quick Guide introduces software environment and development
recommendations for the ABOV 32-bit Touch/LED-Driver MCU Starter Kit. This document also offers
an easy method to develop the Home Appliance Touch.
The Starter Kit Board in this document contains a CMSIS-DAP debugger ‘A-Link’, which allows the
MCU programming and debugging without additional devices.
By following the steps guided in this document, users can build a project and download firmware using
the Keil uVision 5, and learn how to debug the Starter Kit with the A-Link debugger.
In addition, we discuss how to operate the A31T21xRLN Shield Board with examples, step by step.
