Module capsules::usb_user

[−] Expand description

USB system call interface

This capsule provides a system call interface to the USB controller.

Instantiation

The UsbSyscallDriver must be created by passing a reference to something that implements hil::usb::Client (that is, something that is connected to the USBC), as well as a Grant for managing application requests. For example:

// Configure the USB controller
let usb_client = static_init!(
    capsules::usbc_client::Client<'static, sam4l::usbc::Usbc<'static>>,
    capsules::usbc_client::Client::new(&sam4l::usbc::USBC));
sam4l::usbc::USBC.set_client(usb_client);

// Configure the USB userspace driver
let usb_driver = static_init!(
    capsules::usb_user::UsbSyscallDriver<'static,
        capsules::usbc_client::Client<'static, sam4l::usbc::Usbc<'static>>>,
    capsules::usb_user::UsbSyscallDriver::new(
        usb_client, kernel::Grant::create()));
