nRF52 pin configuration

Question

Hi all, I've searched through the devzone but unfortunately my issue is never mentioned. 
 The problem is: my nRF51 project is converted to a nRF52 project. Pins are all re-assigned etc. Now I'm programming but have an issue configuring the pin. Normally when assigning pins I've used for for example pin number 0.05: 
 nrf_gpio_pin_clear(5);
nrf_gpio_cfg_output(5); 
 
 Now with the nRF52 project, I'm trying to assign pin value 1.05: 
 nrf_gpio_pin_clear(32+5);
nrf_gpio_cfg_output(32+5); 
 Unfortunately I get this error:

Please help :)

Hello, 
 Please try to use the NRF_GPIO_PIN_MAP() macro when you configuring pins on PORT 1. 
 e.g., 
 nrf_gpio_pin_clear(NRF_GPIO_PIN_MAP(1,5));

 These symbols should only be defined in your Makefile.

Hi Vidar Berg , 
 
 Your answer has helped me. Removing the NRF52 definition in makefile was the trick. 
 
 Thanks a lot! 
 
 PS: I can't mark your answer as the solution.

Thanks for the update. Yes, -DNRF52 will override your 52840 symbols if set first.
