Setting GPIO voltages

Hi Jakub, 

Thanks for your question online. There is an API in hw_gpio.h driver for configuring the power source of an output pin. 

/**
 * \brief Configure power source for pin output
 *
 * \param [in] port GPIO port
 * \param [in] pin GPIO pin
 * \param [in] power GPIO power source
 *
 */
void hw_gpio_configure_pin_power(HW_GPIO_PORT port, HW_GPIO_PIN pin, HW_GPIO_POWER power);

/**
 * \brief GPIO power source
 *
 */
typedef enum {
        HW_GPIO_POWER_V33 = 0,          /**< V33 (3.3 V) power rail */
        HW_GPIO_POWER_VDD1V8P = 1,      /**< VDD1V8P (1.8 V) power rail */
} HW_GPIO_POWER;

My question is how to do it? Am I setting it "globally" or separately for each pin.

It should be separate for each pin! Please check the comments on hw_gpio_configure_pin_power() API.

Best regards,
