Struct DigitalOutput 

pub struct DigitalOutput {
    pub value: bool,
    /* private fields */
}

Controls a digital output on the Automation HAT.

Digital outputs provide 5V signals for controlling external devices. When an output is set high, it outputs 5V. Each output can have an associated LED that automatically indicates the output state.

Fields

value: bool

Current state of the output (true = high/on, false = low/off)

Implementations

impl DigitalOutput

pub fn new(line: Line, led: Option<LED>) -> Self

Creates a new digital output with automatic LED indication enabled.

Arguments

• line - GPIO line connected to the digital output
• led - Optional LED indicator for this output

Returns

A new DigitalOutput instance with automatic LED indication enabled

pub fn new_with_auto_light( line: Line, led: Option<LED>, auto_light: bool, ) -> Self

Creates a new digital output with configurable LED indication.

Arguments

• line - GPIO line connected to the digital output
• led - Optional LED indicator for this output
• auto_light - Whether the LED should automatically reflect the output state

Returns

A new DigitalOutput instance with the specified LED behavior

pub fn write(&mut self, on: bool) -> Result<(), String>

Sets the state of the digital output.

When on is true, the output is set high (5V). When on is false, the output is set low (0V). If auto_light is enabled and an LED is attached, this method will also update the LED to reflect the current output state.

Arguments

• on - The desired state of the output (true = high/on, false = low/off)

Returns

• Ok(()) - If the output was successfully set
• Err(String) - If setting the output or LED failed, with an error message
