Hi Mathias, I think (but I never implemented any device drivers so take this with a grain of salt) the most sensible solution would be to add a function to the `at86rf2xx` driver that returns a result from the RNG and then wrap it with `periph_hwrng` on all boards that come with this device.
Hope this was helpful, Martine 2016-02-21 19:29 GMT+01:00 Peter Kietzmann <peter.kietzm...@haw-hamburg.de>: > Hi Mathias, > > [1] is the interface that should be implemented by your driver.
