Hi,
As Zhou commented, you can download sample code (including .c and .project) from the following link:
KL25_SC: FRDM-KL25Z and TWRKL25Z48M Sample Code Package.
It is an .exe file, first you need to extract the content. It contains two folders,
1) klxx-sc-baremetal.
For baremetal projects including CW, IAR and Keil examples.Similar projects than "Precompiled Examples" on FRDM-KL25Z_QSP file can be found here.
2) klxx-sc-pex.
For Processor Expert examples.
I hope it helps.
