dwm_gpio_cfg_input

Configures GPIO pin as input.

void dwm_gpio_cfg_input(uint8_t gpio_idx, uint8_t gpio_pull);

Parameters

• gpio_idx – ? 8-bit integer ? (see the section gpio_idx for allowed values)

• gpio_pull – ? 8-bit integer ? (0 no pull, 1 pull down, 3 pull up).

• output – Status code.

C code example

dwm_gpio_cfg_input(DWM_GPIO_IDX_13, DWM_GPIO_PIN_PULLUP);
dwm_gpio_cfg_input(DWM_GPIO_IDX_9, DWM_GPIO_PIN_NOPULL);
dwm_gpio_cfg_input(DWM_GPIO_IDX_31, DWM_GPIO_PIN_PULLDOWN);
