Mapping PX.Y to Number

[comarius]

Hi,

I am new to Nordic chip sets, though I have firmware experience with STM and other boards. I have to wire
an accelerometer to a nRF development board, and fix some existent code. The SPI in the code is
defined like :

My chip is 52832,  s132.

    spi_config.miso_pin = SPI_MISO_PIN;
    spi_config.mosi_pin = SPI_MOSI_PIN;

and

#define SPI_MISO_PIN                  24        
#define SPI_MOSI_PIN                  16        
#define SPI_SCK_PIN                   18           
#define SPI_CS_PIN                    15

I really cannot find Then in RF52_DK_User_Guide_v1.3.1.pdf the 24,16,18,15 or any other pins  to P.X.Y  notation.

for example which PX.Y is 24 ?

I found in some google search code the expression:  Pport.pin =>   (((port) << 5) | ((pin) & 0x1F)) but still not good.

This could be a silly question.

All GPIO on the nrf52832 are on port 0. There is a macro something along the lines of nrf_gpio_pin_map(pin) that will select the correct port (if more than one exists a la the nrf52840).

Thank you.

Test on P0.27 pass.

    nrf_gpio_cfg_output(NRF_GPIO_PIN_MAP(0,27));
    nrf_gpio_pin_set(NRF_GPIO_PIN_MAP(0,27));
