Member Function Documentation
◆ rand()
| uint8_t RNG::rand | ( | ) |
Create a pseudo-random number between 0 and 255.
Simple 8-bit adaption of the Xorshift PRNG.
- Returns
- (uint8_t): The pseudo-random number.
◆ readADC()
|
staticprivate |
Read the LSB from ADC0.
- Precondition
- Requires init() to be called before.
- Returns
- (bit_t): The read LSB.
◆ seed()
| void RNG::seed | ( | ) |
