Software Porting from MKE02 to MKE04

[advangorp]

Hello I am porting my application from MKE02 to MKE04. The development  platform is KDS with Processor Expert. The problem  I met is with the KBI. What  I did on the MKE02 was defining  my key interrupts on the KBI and also on the same pins set BitIO’s so I can poll for double key presses etc. If I want to do the same strategy on the MKE04 I get the Processor Expert error “Selected value is in conflict with other configuration property”. This was not the case on the MKE02. What to do? (The Input is configured for KBI interrupt as well as input).

your support is very much appreciated, kind regards Ad

Hello Kerry, thank you very much for your answer,

I understand that I have to do a low-level pin read without PE. Do you have an example of how I can do that?

Kind regards, Ad

Hi Ad van Gorp

   Of course, we have a lot of low-level code about it, please download the code from these link:

https://www.nxp.com/webapp/Download?colCode=FRDM-KEXX-Driver-Library-Package&appType=license 

 SDK:

Welcome | MCUXpresso SDK Builder 

  Choose the board as KE04/02, then generate the code and download it.

Have a great day,
Kerry

Hello Kerry, could you please be more specific on how to read the input bits PTB0..PTB3 without using the Processor Expert? I tried to incorporate the driver code "FRDM-KEXX-Driver-Library-Package" you linked but did not succeed, Thanks, Ad

Hi Ad van Gorp

   If you are using the PE component, you can check that component help, there will have the according code for your reference.

   Actually, if you just want to to read the PTB0... PTB3 input data.

  You can read the register directly.

 

GPIOA_PIDR |= (1<<8) | (1<<9) | (1<<10) | (1<<11); // enable the input function

Then you can read GPIOA_PDIR data，and check bit8-bit11, it is the PTB0-PTB3 data.

Wish it helps you!

If you still have question about it, please kindly let me know.
Have a great day,
Kerry

Hi Kerry, exactly what I needed, thanks! Ad

Hello Kerry this is the bare bone KDS project file showing the conflict , thanks.

Hi Ad van Gorp,

  I have checked your attached project.

   I know what's going on.

  You can't select the same pin in the different module in the PE component, otherwise, it will report the conflict problems.

  1. You KBI0 choose the PTB0

2. BitIO module, you choose the PTB0 again

So, you meet the problems.

 If you want to use PTB0 as KBI0 pin, please don't configure other module eg BitIO to PTB0 again.

 If you want to get the PTB0 GPIO input status, you totally can use the register control code in the project directly, you don't need to configure the PE module.

Wish it helps you!

Have a great day,
Kerry

Hello Kerry, thank you for the fast response. Below the screenshots you asked for the first seen from the KBI component and the second one from the BitIO.

The problem is on pins PTB0,PTB1,PTB2 and PTB3 as I use the QFP 64-pin package the pin numbers are 34, 33, 32 and 31.

As asked for I created a new project with the MKE04z processor and imported the Processor Expert settings from the 

MKE02 project, this gave the error also.

Then I deleted all imported components and created a new KBI and BitIO component on the same input pin which did not solve the problem.

Please advise, Thank you, Ad

Hi Ad van Gorp,

   Could you please share the new created KDS project which have the problems?

   From your picture, your KBI selected pin is conflict with other component, I will help you to check the details.

Have a great day,
Kery

Hi Ad van Gorp,

  Please also share some screenshots about your problems.

  Which detail pin you used meet that problem?

  Maybe you also can try to create a new project for KE04, and refer to the KE02 to configure the PE component again, that may doesn't have problems.

Have a great day,
Kerry
