Struct WpePins 

pub struct WpePins {
    pub uart_rx: u8,
    pub uart_tx: u8,
    pub psram_ce_n: u8,
    pub psram_sclk: u8,
    pub psram_sio: [u8; 4],
}

Where the engine’s pins land on Caravel’s user GPIOs.

Fields

uart_rx: u8

uart_tx: u8

psram_ce_n: u8

psram_sclk: u8

psram_sio: [u8; 4]

Implementations

impl WpePins

pub fn used(&self) -> Vec<(u8, GpioMode)>

Every used pin with its mode.

pub fn check(&self) -> Result<(), WpeCaravelUnplaceable>

Refuse a housekeeping pin, a pin past the last GPIO, or a pin used twice.

pub fn gpio_modes(&self) -> Vec<(u8, GpioMode)>

The power-on mode of every user GPIO: the plan’s pins as they are used, every other one an input.

Trait Implementations

impl Clone for WpePins

fn clone(&self) -> WpePins

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WpePins

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

Formats the value using the given formatter.

impl PartialEq for WpePins

fn eq(&self, other: &WpePins) -> 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.
