Randomise a base 32-bit number by a jitter factor.
The result is linearly distributed in the jitter range, which is expressed as fixed-point unsigned 1.15 values. For example, to produce a number in the range [0.75 * base, 1.25 * base], set min_factor to 0x6000 and max_factor to 0xA000.
Result is clamped to 0xFFFFFFFF if it overflows.
- Parameters:
-
base The base 32-bit value min_factor The minimum value for the random factor max_factor The maximum value for the random factor
| void randLIB_seed_random | ( | void | ) |
This library is made for getting random numbers for Timing needs in protocols.
**not safe to use for security or cryptographic operations.** Init seed for Pseudo Random.
Makes call(s) to the platform's arm_random_seed_get() to seed the pseudo-random generator.
- Returns:
- None
