    CYW20819 wiced_hal_gpio_init()

    ToKo_4602001

      According to SDK document,

      wiced_hal_gpio_init() must be invoked before accessing any GPIO driver services, typically at boot.

       

      But, on wiced_platform_init() in wiced_platform.c, wiced_hal_gpio_select_function() and wiced_hal_gpio_configure_pin() are used without wiced_hal_gpio_init().

       

      Or is wiced_hal_gpio_init() implicitly called in SDK binary code?

      When /where should I call wiced_hal_gpio_init() in my program?

       

      Thanks
