P0.26, P0.12, P0.13, P0.15, P0.17, P1.10, and P1.13 as switch pins.

P0.02 and P1.15 as LED pins.

above pins, I can map as per requirement

Yes, but P0.12 is used for button on DK, and P0.13/P0.15 is connected to LEDs. Make sure you either use them as specificed in pca10056.h together with BSP, or modify the board header to remove LEDs/BUTTONs or move to other pins.

P0.17 but I tried to connect button and read interrupt, I am not able to get interrupted on this pin.

Meanwhile, I have checked pca10056.h file and found that P0.17 is mapped to "#define BSP_QSPI_CSN_PIN 17"

means I can not use these pins correct?

On the DK, P0.17 is connected to the QSPI external memory chip, and is disconnected from the pin headers by default. You can use it, but you need to cut/solder the solder bridges in order to disconnect from memory and connect to pin headers.

Hi,

There is a change in pin usage.

The hardware team decided to use the below pin as switch configuration

P0.26, P0.12, P0.13, P0.15, P0.17, P1.10, and P1.13 as switch pins.

P0.02 and P1.15 as LED pins.

above pins, I can map as per requirement?

P0.17 but I tried to connect button and read interrupt, I am not able to get interrupted on this pin.

Thanks and Regards

Hi,

Okay, thank you for the feedback.

I will follow the steps and in case of any queries, I will get back to you.

Thanks and Regards

If you want to use LED1 pin for another purpose, I would recommend you to modify the pca10056.h file (or create a custom one for your board), where you either remove LED1, or set LED1 pin to an unused GPIO pin number.

Hi,

Okay, thank you so much for confirmation that I can remap the pins in main.c file without altering to pca10056.h file.

And Regarding this your view,

- Currently in my light bulb Zigbee code it is included and I have kept it without any changes because if the device connects to the Zigbee network LED3 turns ON and I want to keep that same. So without any changes can I use for my custom purpose.?

Thanks and Regards

Yes, sounds like you should be good then.

Hi Jørgen,

Thanks for the quick reply.

So that means if I remap any pins from "serialization application and connectivity board" as per my requirement in the main. c the file then there will be no problem also no need to alter the pac10056.h file.

- Okay, if I remove BSP library then I am good to go with it?.

- Okay,

Hi,

The SER_ defines are all related to Running a serialized application. Since you are using the Thread and Zigbee SDK, I assume you are not using this.

The LEDs/BUTTONs defines are used in BSP. If you want to use the GPIOs for other purposes, you should make sure you do not use the BSP library in your application.

You can follow the instructions in Using the SDK with other boards to create you own custom board file. Then you can remove any defines not used by your application. If any of the defines are used, you will get a compilation error.
