nrfx_gpiote_init undefined reference

[ifithegr8]

Hi,

I have shifted from Arduino to nrf. Arduino is straight forward and with very less dev time. I understand this is way more powerful and next level platform, but does it have to be so painful to work on this platform? 

From the past four hours, I have been struggling with the implementation of the interrupt. I am looking at the code in the example "pin_change_int". Everything makes sense and when i copy the logic to my own program I get following GPIOTE errors. 

I have tried copying sdk_config.h GPIOTE text and enabling it from CMSIS editor. 

I have tried importing nrf_gpiote.c file from modules\nrfx\drivers\src

I watched the video that shows how to import driver. GPIOTE driver does not exist in the given folder

nrf_drv_gpiote. exists in the legacy folder. If it's legacy what is new? 

errors are

undefined reference to `nrfx_gpiote_init'

undefined reference to `nrfx_gpiote_in_init'

undefined reference to `nrfx_gpiote_in_event_enable'

It looks like you have either forgotten to add #include nrfx_gpiote.h to your source file or you have not added the nrfx_gpiote files to your project. 

Check your sdk_config.h for nrfx_gpiote and make sure it is enabled. While you’re there you can also delete references to nrf_drv_gpiote.

It is enabled in sdk_config. What source file are you referring? the example uses nrf_drv_gpiote..h

[Patrick]

The simplest way is probably going to be to change the function calls in your original message to nrf_drv_gpiote_ rather than nrfx_gpiote_

[ifithegr8]

That is what I had previously. The errors are interesting

For people out there they need to do the following. 

1. Include file from nRF5_SDK\modules\nrfx\drivers\src\nrfx_gpiote.c

2. Copy `sdk_config.h` text

// </e> REMOVE ME OR ELSE CMSIS WILL NOT WORK

3. Remove one // </e> from bottom of text out of 2 otherwise CMISS wont work

4. Go armgcc folder and open makefile. in SRC files add $(SDK_ROOT)/modules/nrfx/drivers/src/nrfx_gpiote.c \

Too much to do for a simple task.
