Kinetis SDK Code Portability

[umlengineer]

HI,

I have coded up a KL03 and I have run out of GPIOs so I am going to move to another microcontroller.  I would like to move within the Kinetis family and I am currently looking at the KL13.  I chose this one because it has similar size, if you choose the BGA, more GPIOs and similar deep sleep power performance.  I have coded up the KL03 using the SDK in KDS and I am wondering how portable that code is from one micro in the kinetis SDK to another.  I understand that without seeing my code its a little hard to guess, but I was wondering if someone could offer some guidance on the subject.  My hope is that I just have to download a version of the SDK for the KL13, change the pinmux.c file and any defines that point to hardware and be pretty close to a functional code base. 

Hopefully that is clear.

Thanks!

Hi Evan Griffith,

      Thank you for your interest in NXP kinetis product, I would like to provide service for you.

      You can download the KL13 SDK code from this link:

 https://mcuxpresso.nxp.com/en/select 

It is based on the KL43 board, then you just need to modify the according files, which can be found in folder:SDK_2.5.0_MKL13Z64xxx4\devices\MKL13Z644

Wish it helps you!

If you still have question about it, please kindly let me know.

Have a great day,
Kerry

Hi,

Thanks for the info, I have done that in the past to get SDKs and it has worked well.  I am really interested in how migratable code is from one microcontroller in the Kinetis SDK family to another. 

Thanks for your reply.

Hi Evan,

    Could you tell me what the IDE you want to use now? MCUxpresso IDE or others?

    Then I will tell you how to migrate, and the detail point.

Waiting for your reply!
Have a great day,
Kerry

Hi,

Currently it is coded in KDS AKA Kinetis Design Studio, but I will be migrating to MCUExpresso.  Depending on the process I will migrate the MCUExpresso and to the new MCU at the same time or I will do it at the same time. 

Thanks for all your help on this!

Hi Evan Griffh,

    I suggest you use the MCUXpresso IDE instead of the KDS.

   Then you can open the SDK for KL43, and modify the according KL43 source code to KL13.

1. startup file change to KL13, you can find it from folder:

SDK_2.5.0_MKL13Z64xxx4\devices\MKL13Z644\mcuxpresso

2. Change the project device folder files, which can be found in folder :

DK_2.5.0_MKL13Z64xxx4\devices\MKL13Z644

3. Change the drivers folder with :SDK_2.5.0_MKL13Z64xxx4\devices\MKL13Z644\drivers

4. Change the MCU to your KL13 chip:

Please try it on your side.

If you still have problems about it, please kindly let me know.

Have a great day,
Kerry
