How to configure only Port0 all pins as GPIO with nrf52832

[jeevan.k]

Hi Team,

I am new to nrf and using Nrf52832 and  SDK 14.2.0 for development I am facing a problem, I want to select only Port0 pins as GPIO pins. how to make it. I gone through nrf_gpio.h file I am not understanding much please suggest me.

With thanks

So why start with such an old SDK ?

Look at the examples which illustrate how to use the SDK facilities ...

Thanks for your valuable reply.

But I am not understanding how to make pins P0.00 to P0.07 as GPIO all at a time, I need to make some GPIOS as high and remaining as low in a loop, any code sample to achieve this it will be very helpful.

Thanks

Hi Jeevan.

To configure a pin as output you just need to use (Assuming your LED is on pin 7)

#define LED_PIN 7

nrf_gpio_cfg_output(LED_PIN);// Set LED PIN pin as output

To set the pin to High , use

nrf_gpio_pin_set(LED_PIN);

to set the pin to low, use

nrf_gpio_pin_clear(LED_PIN);

to toggle the pin use

nrf_gpio_pin_toggle(LED_PIN);

Note. You need to include "nrf_gpio.h"

Best regards,

Thanks for the reply

but i want to use this function nrf_gpio_port_dir_input_set(NRF_GPIO_Type * p_reg, uint32_t in_mask); which is in "nrf_gpio.h"

so that I can control all the pins at a time how make use of this???

Thanks

Hi.

You can use that function to set all the pins as input like this for example:

nrf_gpio_port_dir_input_set(~0);

Best regards,
