Struct Driver

pub struct Driver<'d, T: Instance> { /* private fields */ }

USB driver.

Implementations

impl<'d, T: Instance> Driver<'d, T>

pub fn new_fs( _peri: Peri<'d, T>, _irq: impl Binding<T::Interrupt, InterruptHandler<T>> + 'd, dp: Peri<'d, impl DpPin<T>>, dm: Peri<'d, impl DmPin<T>>, ep_out_buffer: &'d mut [u8], config: Config, ) -> Self

Initializes USB OTG peripheral with internal Full-Speed PHY.

Arguments

• ep_out_buffer - An internal buffer used to temporarily store received packets. Must be large enough to fit all OUT endpoint max packet sizes. Endpoint allocation will fail if it is too small.

pub fn new_hs( _peri: Peri<'d, T>, _irq: impl Binding<T::Interrupt, InterruptHandler<T>> + 'd, _dp: Peri<'d, impl DpPin<T>>, _dm: Peri<'d, impl DmPin<T>>, ep_out_buffer: &'d mut [u8], config: Config, ) -> Self

Initializes USB OTG peripheral with internal High-Speed PHY.

Arguments

• ep_out_buffer - An internal buffer used to temporarily store received packets. Must be large enough to fit all OUT endpoint max packet sizes. Endpoint allocation will fail if it is too small.

pub fn new_fs_ulpi( _peri: Peri<'d, T>, _irq: impl Binding<T::Interrupt, InterruptHandler<T>> + 'd, ulpi_clk: Peri<'d, impl UlpiClkPin<T>>, ulpi_dir: Peri<'d, impl UlpiDirPin<T>>, ulpi_nxt: Peri<'d, impl UlpiNxtPin<T>>, ulpi_stp: Peri<'d, impl UlpiStpPin<T>>, ulpi_d0: Peri<'d, impl UlpiD0Pin<T>>, ulpi_d1: Peri<'d, impl UlpiD1Pin<T>>, ulpi_d2: Peri<'d, impl UlpiD2Pin<T>>, ulpi_d3: Peri<'d, impl UlpiD3Pin<T>>, ulpi_d4: Peri<'d, impl UlpiD4Pin<T>>, ulpi_d5: Peri<'d, impl UlpiD5Pin<T>>, ulpi_d6: Peri<'d, impl UlpiD6Pin<T>>, ulpi_d7: Peri<'d, impl UlpiD7Pin<T>>, ep_out_buffer: &'d mut [u8], config: Config, ) -> Self

Initializes USB OTG peripheral with external Full-speed PHY (usually, a High-speed PHY in Full-speed mode).

Arguments

• ep_out_buffer - An internal buffer used to temporarily store received packets. Must be large enough to fit all OUT endpoint max packet sizes. Endpoint allocation will fail if it is too small.

pub fn new_hs_ulpi( _peri: Peri<'d, T>, _irq: impl Binding<T::Interrupt, InterruptHandler<T>> + 'd, ulpi_clk: Peri<'d, impl UlpiClkPin<T>>, ulpi_dir: Peri<'d, impl UlpiDirPin<T>>, ulpi_nxt: Peri<'d, impl UlpiNxtPin<T>>, ulpi_stp: Peri<'d, impl UlpiStpPin<T>>, ulpi_d0: Peri<'d, impl UlpiD0Pin<T>>, ulpi_d1: Peri<'d, impl UlpiD1Pin<T>>, ulpi_d2: Peri<'d, impl UlpiD2Pin<T>>, ulpi_d3: Peri<'d, impl UlpiD3Pin<T>>, ulpi_d4: Peri<'d, impl UlpiD4Pin<T>>, ulpi_d5: Peri<'d, impl UlpiD5Pin<T>>, ulpi_d6: Peri<'d, impl UlpiD6Pin<T>>, ulpi_d7: Peri<'d, impl UlpiD7Pin<T>>, ep_out_buffer: &'d mut [u8], config: Config, ) -> Self

Initializes USB OTG peripheral with external High-Speed PHY.

Arguments

• ep_out_buffer - An internal buffer used to temporarily store received packets. Must be large enough to fit all OUT endpoint max packet sizes. Endpoint allocation will fail if it is too small.
