Setting GPIO voltages

Hello,

I found in DA14683 data sheet that I can program voltage levels on GPIOs:

"

37 (AQFN) or 21 (WLCSP) general purpose I/Os with programmable voltage levels

"

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

Regards Jakub

  • 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.
