Introduction
The HT32F1654 Starter Kit is based around the 32-bit ARM CortexTM-M3 high performance
microcontroller and is designed to assist users to get up and running with this device as quickly as
possible. It provides a complete solution from evaluation, programming to production.
This development platform is composed of a Target Board and Serial-Wire Debugger (e-Link32
Lite) and as such requires no external debugging equipment. It can use the Target Board external
power supply or be powered by the Debugger.
The Starter Kit provides a standard C language program development environment for Keil μVision
and IAR EWARM. With this basis, Holtek also provides a complete function library to avoid
complicated lower level function development in order to allow development designers to focus
on the needs of their application development. Using a simple USB cable connection, users only
have to connect their PC to the integrated hardware debug interface (Serial-Wire Debugger), to
automatically download the programs and immediately commence debug operations.
