That tool is very easy to use, especially for the freshmen to start their development on embedded system.The useful tool I want to recommend to you is: CoIDE and a series of software developed by CooCox.
If you are a freshmen to the design of embedded system, you will find CoIDE very easy to use because the examples and components will help you to understand how to make a design by the CoIDE.
If you want to search for some information about the chips which CooCox software supported, then CoAssitant will help.
CoFlash can be use to download program to chips though CoLinkex, whitch is an open and free debugging probes design for ARM Cortex M3 and Cortex M0 MCUs.
The most important thing is, all of the software develop by CooCox is totally free. You don't need to pay any fee to CooCox. CoLinkex can be bought from 2CO or do it by yourself.
For more information, you can vist the website of coocox:http://www.coocox.org.
