When to use CMSIS peripheral driver?

[idof]

Hi,

Coming to plan my sw architecture and after going over the SDK examples I wonder when should I use the standard peripheral driver versus the CMSIS driver?

What's the considerations when choosing between them?

Are they both updated?

Which of these two is more robust?

Thank you

Hi idof 

CMSIS-Driver is ARM MDK Middleware.CMSIS-Driver is designed for multi semiconductor company products. NXP is one of the vendor

If user has requirement to port the code to other semiconductor device, using CMSIS driver would be easier.But please note, There are not many CMSIS demo released so far.
“ standard peripheral driver" are produced and mantained by NXP.

Hope this will help you.
