Implementations

impl TsNbus

pub fn new() -> Self

Creates a new instance.

pub fn set_data_pin( &mut self, index: usize, pin: GpioPin, ) -> Result<(), BusError>

Wires one of the 8 data lines (index 0..8) to a GPIO pin. Returns BusError::InvalidArgument when index >= 8.

pub fn set_control_pin(&mut self, which: NbusControlPin, pin: GpioPin)

Wires a control line to a GPIO pin.

fn validate_pins(&self) -> Result<(), BusError>

Verifies that every pin required by the bit-banging protocol is configured, so transactions fail loudly instead of silently no-op’ing.

fn set_data_direction(&self, output: bool)

Sets data direction.

fn write_byte(&self, val: u8)

Writes byte.

fn read_byte(&self) -> u8

Reads byte.

fn start_transaction(&self)

Starts transaction.

fn end_transaction(&self)

Performs the end transaction operation.

fn wait_rdy(&self) -> Result<(), BusError>

Performs the wait rdy operation.

fn reset_bus(&self)

Performs the reset bus operation.

pub fn bus_read(&self, address: u16) -> Result<u16, BusError>

Performs the bus read operation.

pub fn bus_write(&self, address: u16, value: u16) -> Result<(), BusError>

Performs the bus write operation.

pub fn add_child(&mut self, child: BusChild)

Performs the add child operation.

Trait Implementations

impl BusDriver for TsNbus

fn name(&self) -> &str

Performs the name operation.

fn compatible(&self) -> &[&str]

Performs the compatible operation.

fn probe(&self) -> bool

Requires explicit GPIO pin configuration; no auto-detect.

fn init(&mut self, _base: usize) -> Result<(), BusError>

Performs the init operation.

fn shutdown(&mut self) -> Result<(), BusError>

Performs the shutdown operation.

fn read_reg(&self, offset: usize) -> Result<u32, BusError>

Reads reg.

fn write_reg(&mut self, offset: usize, value: u32) -> Result<(), BusError>

Writes reg.

fn children(&self) -> Vec<BusChild>

Performs the children operation.

fn as_firewall(&self) -> Option<&dyn FirewallController>

Returns the optional [FirewallController] capability, if any.

fn suspend(&mut self) -> Result<(), BusError>

Performs the suspend operation.

fn resume(&mut self) -> Result<(), BusError>

Performs the resume operation.

fn error_count(&self) -> u64

Performs the error count operation.

fn handle_irq(&mut self) -> bool

Handles irq.
