[in]	value	value of the pin, each pin corresponds to a bit, 1 means high, 0 means low
[in]	pin_mask	pin mask, each pin corresponds to one bit, 1 means the corresponding pin needs to be written, 0 means the corresponding pin does not need to be updated

◆ vsf_gpio_set()

◆ vsf_gpio_toggle()

void vsf_gpio_toggle	(	vsf_gpio_t *	gpio_ptr,
		vsf_gpio_pin_mask_t	pin_mask

[in]	pin_mask	pin mask, each pin corresponds to one bit, 1 means the corresponding pin needs to be written, 0 means the corresponding pin does not need to be updated

◆ vsf_gpio_config()

vsf_err_t vsf_gpio_config	(	vsf_io_cfg_t *	cfg,
		uint_fast8_t	count
	)

gpio batch configuration an implementation example:

static bool vsf_gpio_config( vsf_io_cfg_t *cfg_ptr, uint_fast8_t count ) { bool result = true; if (NULL == cfg_ptr || 0 == count) { return false; }

! io configure do { uint_fast8_t pin_index = cfg_ptr->pin_index; //!< get pin index number uint32_t function = cfg_ptr->function; //!< get pin function selection

! get pin feature and make sure pin-input is enabled by default ! this is an example to enable some feature to be default. uint_fast8_t feature = cfg_ptr->feature ^ IOCTRL_PIN_IE_MSK;

! set pin feature: this is the most optimal solution GSP_IOCTRL.PIN[pin_index].Value = feature;

! but if we are not lucky enough, we can only use the following way if (feature & VSF_IO_PULL_UP) { IOCTRL_ENABLE_PULL_UP(pin_index); } else { IOCTRL_DISABLE_PULL_UP } if (feature & VSF_IO_HIGH_DRV) { IOCTRL_ENABLE_HIGH_DRIVER_STRENGH(pin_index); } else { IOCTRL_DISABLE_HIGH_DRIVER_STRENGH(pin_index); } ...

! I know this is ugly, but some times, the two methods aforementioned ! can be combined. So you should fully use the 32 bit of the ! cfg_ptr->feature

! set pin function selection IOCTRL_FUNCTION_SELECT(pin_index, function);

    cfg_ptr++;                                //!< next one...
} while(--count);

return result;

}

!

Parameters

cfg	the pointer points to configuration array !
count	the count of configurations in the array !

Returns: configuration result
