[−][src]Struct linux_embedded_hal::CdevPin
Newtype around gpio_cdev::LineHandle that implements the embedded-hal traits
Implementations
impl CdevPin[src]
pub fn new(handle: LineHandle) -> Result<Self, Error>[src]
See gpio_cdev::Line::request for details.
Methods from Deref<Target = LineHandle>
pub fn get_value(&self) -> Result<u8, Error>[src]
Request the current state of this Line from the kernel
This call is expected to succeed for both input and output lines. It should be noted, however, that some drivers may not be able to give any useful information when the value is requested for an output line.
This value should be 0 or 1 which a "1" representing that the line is active. Usually this means that the line is at logic-level high but it could mean the opposite if the line has been marked as being ACTIVE_LOW.
pub fn set_value(&self, value: u8) -> Result<(), Error>[src]
Request that the line be driven to the specified value
The value should be 0 or 1 with 1 representing a request to make the line "active". Usually "active" means logic level high unless the line has been marked as ACTIVE_LOW.
Calling set_value on a line that is not an output will
likely result in an error (from the kernel).
pub fn line(&self) -> &Line[src]
Get the Line information associated with this handle.
