Hi Rong,
Do you refere to the sample code provide in the K20, K60... web page? Unfortunately these examples have not been ported to KDS.
You can find a guide showing how to port a project form CW to KDS in the KDS installation path...
C:\Freescale\KDS_3.0.0\doc\KDS_Porting_Guide.pdf
However I think that the cleanest way to port a project is to create a new KDS project and copy/add all the source files/libraries/settings form the CW project.
You may also take a look to our new KSDK (Kinetis Software developmet Kit). It is a set of peripheral drivers provided as librares but including source code. It contains many The newest version is KSDK2.0.
Please take a look to the following post.
