Expand description

Generic abstraction over a GPIO chip to back all EndBASIC commands.

Required Methods§

Source

fn setup(&mut self, pin: Pin, mode: PinMode) -> Result<()>

Configures the pin as either input or output (per mode).

This lazily initialies the GPIO chip as well on the first pin setup.

It is OK to set up a pin multiple times without calling clear() in-between.

Source

fn clear(&mut self, pin: Pin) -> Result<()>

Resets a given pin to its default state.

Source

fn clear_all(&mut self) -> Result<()>

Resets all pins to their default state.

Source

fn read(&mut self, pin: Pin) -> Result<bool>

Reads the value of the given pin, which must have been previously setup as an input pin.

Source

fn write(&mut self, pin: Pin, v: bool) -> Result<()>

Writes v to the given pin, which must have been previously setup as an output pin.
