Struct SharedSpiLogicState 

pub struct SharedSpiLogicState {
    pub lcd_cs_low: bool,
    pub sd_cs_low: bool,
    pub gpio35: SharedGpio35Role,
}

Pure CoreS3 shared-SPI invariant model used by host tests and docs.

Fields

lcd_cs_low: bool

sd_cs_low: bool

gpio35: SharedGpio35Role

Implementations

impl SharedSpiLogicState

pub const SAFE_IDLE: Self

Safe CoreS3 shared-SPI idle state: both CS lines high and GPIO35 MISO-safe.

pub const fn begin_lcd(self) -> Self

Begin an LCD transaction: SD CS high, GPIO35 D/C output, LCD CS low.

pub const fn begin_sd(self) -> Self

Begin an SD transaction: LCD CS high, GPIO35 MISO-safe, SD CS low.

pub const fn safe_idle(self) -> Self

End or clean up either transaction into the BSP’s safe idle state.

pub const fn invariants_hold(self) -> bool

Whether the model satisfies CoreS3’s LCD/SD shared-bus invariants.
