Hi Mathias,

I think the way to go here is to implement the `drivers/include/periph/hwrng.h` interface. For this I think it makes sense to add a function that reads the random data from the radio to the at86rf2xx driver and call this function from the hwrng driver.

Cheers,
Hauke

Hy!

I would like to use the hardware RNG from my samr1-xpro board. It should be 
available by reading out a certain register, according to the AT86RF233 
documentation.
My problem is, that I don't how to do that (I am pretty new to this stuff). Is 
there some documentation available for this kind of task, or could you point me 
in the right
direction?

cheers
Mathias
