Cheat sheet for nrf sdk:

sleep: k_msleep(ms)

To interact with the GPIO peripheral,USE API <zephyr/drivers/gpio.h>

Get the GPIO pin INIT and READY:

struct gpio_dt_spec led = GPIO_DT_SPEC_GET(DT_NODELABEL(led0), gpios); if (!device_is_ready(led.port)) { return; }

Configure GPIO PIN: gpio_pin_configure_dt(&led, GPIO_OUTPUT); SET PIN LOW: gpio_pin_configure_dt(&led, GPIO_OUTPUT | GPIO_ACTIVE_LOW);

OR gpio_pin_set_dt(&led, 1);

OR Toogle it: gpio_pin_toggle_dt(&led);

OR READ: uint8_t val = gpio_pin_get_dt(&led);

SET INT MODE: gpio_pin_interrupt_configure_dt(&button,GPIO_INT_EDGE_TO_ACTIVE);

Get the UART node ready:

const struct device *dev; dev = DEVICE_DT_GET(DT_NODELABEL(uart0));

if (!device_is_ready(dev)) { return; }

I2C:

set config: CONFIG_I2C=y call driver: #include <zephyr/drivers/i2c.h>
