How to prevent the crypto library from using the watchdog timer? #31

Closed bmanga closed 6 years ago

bmanga commented 6 years ago

CRYPTO/RNG.cpp uses the watchdog to generate entropy, however I need to use it for other purposes. I see that part is guarded by a macro, but setting RNG_WATCHDOG to 0 causes compilation errors. Is there a simple way to disable it?

Try commenting the line out completely rather than setting it to 0; i.e.:

//#define RNG_WATCHDOG 1

You may also need to comment out the "no hardware random number source" error/warning. You will need a separate noise source to replace the watchdog of course.

I hope this helps.

Hi, I am using in the same sketch LowPower library and this library. I have problems to use another source of noise. Could I get any simple example ? Thanks.
