SOLVED - Pyboard lite does not generates random numbers

[ovelap]

Hi,
I want to blink with with one random LED from numbers od LEDs. LEDs are connected to pyboard. In micropython-lib there is dummy module random without funcionality. Exists another solution for it - generate random number in pyboard?

Thanks.

pyb.rng() is your friend: http://docs.micropython.org/en/latest/p ... y/pyb.html.

Thanks for your answer. But:

>>> import pyb
>>> pyb.rng()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'rng'
>>>

pyb.rng() is not accessible (last firmware 1.8.6).

not all pyboard support pyb.rng(), some device has not random number generator modual, such as STM32F401/F411.

I have found this:
https://github.com/rguillon/micropython ... dom/random

I think that it generates "pseudo random" numbers (I am not math guy....). It is good solution for my project. LEDs looks like blinking randomously .

Thank to everybody who answered to my question.
