Trait synopsys_usb_otg::UsbPeripheral

pub unsafe trait UsbPeripheral: Send + Sync {
    const REGISTERS: *const ();
    const HIGH_SPEED: bool;
    const FIFO_DEPTH_WORDS: usize;
    const ENDPOINT_COUNT: usize;

    fn enable();
    fn ahb_frequency_hz(&self) -> u32;

    fn phy_type(&self) -> PhyType { ... }
    fn setup_internal_hs_phy(&self) { ... }
}

A trait for device-specific USB peripherals. Implement this to add support for a new hardware platform. Peripherals that have this trait must have the same register block as STM32 USB OTG peripherals.

Associated Constants

const REGISTERS: *const ()

Pointer to the register block

const HIGH_SPEED: bool

true for High Speed variants of the peripheral, false for Full Speed

const FIFO_DEPTH_WORDS: usize

FIFO size in 32-bit words

const ENDPOINT_COUNT: usize

Number of (bidirectional) endpoints

Required methods

fn enable()

Enables USB device on its peripheral bus

fn ahb_frequency_hz(&self) -> u32

AHB frequency in hertz

Provided methods

fn phy_type(&self) -> PhyType

Returns PHY type that should be used for USB peripheral

fn setup_internal_hs_phy(&self)

Performs initial setup of the internal high-speed PHY

This function should turn on LDO and PLL and wait for PHY clock to become stable.
