dwm_gpio_value_get

Reads pin value.

void dwm_gpio_value_get(uint8_t gpio_idx, uint8_t *value);

Parameters

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

• output – Status code [, gpio_val].

• gpio_val – ‘0’ | ‘1’

C code example

uint8_t value;
dwm_gpio_value_get(DWM_GPIO_IDX_13, &value);
printf("%u\n”, value);
