Sharing pins with PE 3.0.1 and KDS 3.0.0

michaelgoudey — Wed, 11 Nov 2015 00:27:01 GMT

I'm trying to enable pin sharing in KDS v3.0.0 with associated PE version 3.0.1. My target device is MK22FN512. I was able to get this working with KDS v2.0.0 and its associated Processor Expert, but it doesn't seem to work in KDS3.

PEx_for_Kinetis_User_Manual.pdf has section 3.3.8 on pin sharing. There is no Expert mode any more, so the documentation is not up to date. I'm unable to see the pop-up Pin Sharing menu option under a peripheral pin.

Is this still possible with PE 3.0.1? I try setting ConnectPin Method to "generate code" and it doesn't help.

Regards,

Michael Goudey

Hello Michael,

I have reproduced the issue. The MK22FN512 should support different concept. There is PinSettings component supported and these conflict should be resolved by settings "Ignore Constraints and non-Critical Error" that is available in the Component Inspector of the component, see below:

But it seems that this settings does not work in all cases. I have created issue (PEXMCU-4060) to the responsible development team.

I've run into this issue as well. I've got a PPG and GPIO components sharing a pin on a K64. Ignoring constraints cleared the error from the PPG, but not from the GPIO_LDD.

Can we get an update on the status of the fix? What would you recommend I do to get past this now?

Hi,

Is there a fix or workaround available? For me the "Ignore Constrains and non-critical Errors" checkbox is grayed out. Same for the "Share Pin Enable" menue entry.

I am useing KDS 3.2.0 with PE for a MK22FN256 and I am not able to use pin sharing at all...
