Function Documentation
◆ gpio_clear()
| void gpio_clear | ( | uint32_t | gpioport, |
| uint32_t | gpios | ||
| ) |
◆ gpio_disable()
| void gpio_disable | ( | uint32_t | gpioport, |
| uint32_t | gpios | ||
| ) |
Disable output pins.
Onlyc the ones where bits are set to "1" are touched, everything else remains in the old state.
- Parameters
-
[in] gpioport uint32_t: GPIO Port base address [in] gpios uint32_t

◆ gpio_enable()
| void gpio_enable | ( | uint32_t | gpioport, |
| uint32_t | gpios, | ||
| enum gpio_mode | mode | ||
| ) |
