Module capsules::rng

Provides a simple driver for userspace applications to request randomness.

The RNG accepts a user-defined callback and buffer to hold received randomness. A single command starts the RNG, the callback is called when the requested amount of randomness is received, or the buffer is filled.

Usage

let rng = static_init!(
        capsules::rng::SimpleRng<'static, sam4l::trng::Trng>,
        capsules::rng::SimpleRng::new(&sam4l::trng::TRNG, kernel::Grant::create()));
sam4l::trng::TRNG.set_client(rng);
