Hi @neilporven
Thanks for your interest in the NXP kinetis product, I would like to provide service for you.
Your SDK1.3 is really very old and it is out of support now.
Please use the newest SDK which can be downloaded from this link:
https://mcuxpresso.nxp.com/
I have checked the newest SDK for KL43, it contains the slcd examples:
SDK_2.8.0_FRDM-KL43Z\boards\frdmkl43z\driver_examples\slcd


Already have the fsl_slcd drivers.
Wish it helps you!
If you still have questions about it, please kindly let me know.
Best Regards,
kerry
