Implementations

impl GpioChip

pub fn new<P: AsRef<Path>>(path: P) -> Result<GpioChip>

Open the gpiochip with the provided path

Typically, the path will be something like "/dev/gpiochip0".

pub fn info(&self, gpio: u32) -> Result<LineInfo>

Acquire information about a gpio

pub fn request( &self, consumer: &str, flags: RequestFlags, gpio: u32, default: u8, ) -> Result<GpioHandle>

Request a GpioHandle for a single gpio

pub fn request_array( &self, consumer: &str, flags: RequestFlags, gpios: &[u32], default_values: &[u8], ) -> Result<GpioArrayHandle>

Request a GpioArrayHandle for multiple gpios, that should be get/set simultaneously

pub fn request_event( &self, consumer: &str, gpio: u32, handleflags: RequestFlags, eventflags: EventRequestFlags, ) -> Result<GpioEventHandle>

Request a GpioEventHandle for a single gpio
