Struct LiteXGPIOController

pub struct LiteXGPIOController<'client, R: LiteXSoCRegisterConfiguration> { /* private fields */ }

LiteX Tristate GPIO controller core

Implementations

impl<'client, R: LiteXSoCRegisterConfiguration> LiteXGPIOController<'client, R>

pub fn new( base: StaticRef<LiteXGPIORegisters<R>>, gpio_count: usize, ) -> LiteXGPIOController<'client, R>

pub fn initialize(&self)

Initialize the LiteXGPIOController

This will set all GPIOs to be inputs.

pub fn gpio_count(&self) -> usize

Returns the number of GPIOs managed by the LiteXGPIOController

pub fn get_gpio_pin<'controller>( &'controller self, index: usize, ) -> Option<LiteXGPIOPin<'controller, 'client, R>>

Create a LiteXGPIOPin instance

To avoid duplicate use of a GPIO, this will return None if an instance for the requested GPIO already exists. Call LiteXGPIOPin::destroy (or drop the LiteXGPIOPin) to be able to create a new instance for this GPIO.
