Struct Driver 

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

USB driver.

Implementations

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

pub fn new_with_sof( _usb: Peri<'d, T>, dp: Peri<'d, impl DpPin<T>>, dm: Peri<'d, impl DmPin<T>>, sof: Peri<'d, impl SofPin<T>>, _irq: impl Binding<T::Interrupt, InterruptHandler<T>> + 'd, ) -> Self

Create a new USB driver with start-of-frame (SOF) output.

pub fn new_with_sof_and_vbus( _usb: Peri<'d, T>, dp: Peri<'d, impl DpPin<T>>, dm: Peri<'d, impl DmPin<T>>, sof: Peri<'d, impl SofPin<T>>, vbus: ExtiInput<'d, Async>, _irq: impl Binding<T::Interrupt, InterruptHandler<T>> + 'd, ) -> Self

Create a new USB driver with start-of-frame (SOF) output and VBUS detection.

pub fn new( _usb: Peri<'d, T>, dp: Peri<'d, impl DpPin<T>>, dm: Peri<'d, impl DmPin<T>>, _irq: impl Binding<T::Interrupt, InterruptHandler<T>> + 'd, ) -> Self

Create a new USB driver.

pub fn new_with_vbus( _usb: Peri<'d, T>, dp: Peri<'d, impl DpPin<T>>, dm: Peri<'d, impl DmPin<T>>, vbus: ExtiInput<'d, Async>, _irq: impl Binding<T::Interrupt, InterruptHandler<T>> + 'd, ) -> Self

Create a new USB driver with VBUS detection through an EXTI input.

Wire VBUS to a GPIO: this USB peripheral only has USB_DP, USB_DM and USB_NOE pins and no VBUS input (RM0444 37.4.2), and its suspend event only means the host stopped traffic for 3 ms (RM0444 37.5.7), not that the cable was removed.

When vbus goes low, Bus::poll reports Event::PowerRemoved and the endpoints are disabled, so pending reads and writes return EndpointError::Disabled. When it goes high again, Event::PowerDetected is reported and the USB stack re-enumerates.
