本文介绍了一种调试工具。硬件上利用了商品化的低价设备，因为其电路极其简单，所以也完全可以自行制作。软件基于开放源码平台GNU的GDB调试程序，没有任何版权的问题，而且开放源码的特性使得功能的添加和修改完全自主可控，具有良好的可扩展性；另外其可移植性也比较好，理论上在任何

类UNIX平台上都能移植。此系统实际在linux和cygwin上都已能正常工作。-This paper presents a debugging tool. Use of commercial hardware, low-cost device, because the circuit is very simple, so it can produce their own. Platform based on open source software GNU' s GDB debugger, there is no copyright issue, but the features that make open source add and modify functions completely independent and controllable, with good scalability　also its portability is relatively good, Theory on the UNIX platform in any class can be transplanted. This system actually have on linux and cygwin to work.
