Random number without softdevice

[tomole]

Hi,

I am working with nRF51 for my application. I do not use softdevices. I need to have a random variable in my code. I have read Reference Manual and I have found that random numbers can be made by RNG. Some registers are described in documentation for the RNG, but nothing more. I do not know how to use them in order to give a random value to my variable in main. Can anybody help me with that?

Hi,

There is a RNG example in the SDK:

<SDK_InstallFolder>\examples\peripheral\rng

If you dont want to use the SDK RNG driver, you can also find a bare-metal example on how to use the RNG peripheral here.
