    Hi,

    there are some libraries for generate random integer?

    Now I have used srand() and rand() of Hiware.

    srand() setting start value.

    rand() generate random integer binded of start value.

    star value = ADC1 + ADC2

    ADC1= humidity sensor

    ADC2= temperature sensor

    This not very good algorithm :-[

    Other solution? Thanks

    I use ST325K6.

    Bye

    I posted this to another thread about random numbers but since you're looking:

    This code uses hardware on the stm32f103 to generate true random numbers without having to add any new hardware: http://www.gniibe.org/memo/development/gnuk/rng/pqrng

    You probably can't use this directly but should be pretty easy to modify for your needs.
