3.1. Guide to using CDK (like MDK Keil) under Windows

This document introduces the use of the CDK developed by T-HEAD Semiconductor under Windows to complete the related software development of BL702 series MCU.

Regarding T-HEAD CDK, this is an integrated development environment developed by T-HEAD. It has operations and settings that are very similar to the traditional MCU development environment, and aims to fully access cloud development resources without changing user development habits, combined with graphical debugging and analysis tools such as OSTracer and Profiling, to accelerate user product development.
