# embassy-usb-driver
|
|
|
|
|
|
|
|
|
|
This crate contains the driver traits for [`embassy-usb`]. HAL/BSP crates can implement these
|
|
|
|
|
traits to add support for using `embassy-usb` for a given chip/platform.
|
|
|
|
|
|
|
|
|
|
The traits are kept in a separate crate so that breaking changes in the higher-level [`embassy-usb`]
|
2023-11-25 21:31:03 +00:00
|
|
|
APIs don't cause a semver-major bump of this crate. This allows existing HALs/BSPs to be used
|

|
|
|
with the newer `embassy-usb` without needing updates.
|
|
|
|
|
|
|
|
|
|
If you're writing an application using USB, you should depend on the main [`embassy-usb`] crate
|
|
|
|
|
instead of this one.
