Struct Wiring 

pub struct Wiring {
    pub spi: PathBuf,
    pub spi_hz: u32,
    pub gpio_chip: PathBuf,
    pub reset_line: u32,
    pub busy_line: Option<u32>,
}

Where a radio module is wired on a Linux board.

Examples

use pamoja_radios::linux::{Wiring, DEFAULT_SPI_HZ};

// An SX1262 board on SPI0's second chip select, BUSY on GPIO24 and reset on GPIO25.
let wiring = Wiring::new("/dev/spidev0.1", "/dev/gpiochip0", 25).with_busy_line(24);
assert_eq!(wiring.busy_line, Some(24));
assert_eq!(wiring.spi_hz, DEFAULT_SPI_HZ);

Fields

spi: PathBuf

The SPI device file, one per chip select, such as /dev/spidev0.0.

spi_hz: u32

The SPI clock in hertz.

gpio_chip: PathBuf

The GPIO chip the lines are on, /dev/gpiochip0 for a Raspberry Pi’s header.

reset_line: u32

The line the module’s reset pin is on: its offset on the chip, which on a Raspberry Pi is the BCM GPIO number.

busy_line: Option<u32>

The line an SX126x’s BUSY pin is on. The SX127x has no BUSY pin.

Implementations

impl Wiring

pub fn new( spi: impl Into<PathBuf>, gpio_chip: impl Into<PathBuf>, reset_line: u32, ) -> Wiring

Describes a module on an SPI device with its reset pin on a GPIO line, clocked at DEFAULT_SPI_HZ and with no BUSY line.

Arguments

• spi - the SPI device file.
• gpio_chip - the GPIO chip the lines are on.
• reset_line - the line the reset pin is on.

Returns

The wiring.

pub fn with_busy_line(self, line: u32) -> Wiring

Returns the wiring with an SX126x’s BUSY pin on a line.

Arguments

• line - the line the BUSY pin is on.

Returns

The wiring.

pub fn with_spi_hz(self, hz: u32) -> Wiring

Returns the wiring with another SPI clock.

Arguments

• hz - the clock in hertz.

Returns

The wiring.

Trait Implementations

impl Clone for Wiring

fn clone(&self) -> Wiring

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Wiring

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Wiring

impl Hash for Wiring

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Wiring

fn eq(&self, other: &Wiring) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
